40 MCQ Quiz - Joints of the Upper Limb

Based on Gray's Anatomy for Students & verified anatomical sources

SHOULDER GIRDLE JOINTS (Q1-8)

Q1. The sternoclavicular joint is classified as which type of synovial joint?

A) Hinge joint
B) Pivot joint
C) Saddle joint
D) Ball and socket joint

✅ Answer: C - Saddle joint The sternoclavicular joint is a saddle (sellar) joint. It is the only true bony articulation between the upper limb and the axial skeleton.

Q2. Which ligament is the strongest and most important stabilizer of the sternoclavicular joint, preventing upward displacement of the clavicle?

A) Anterior sternoclavicular ligament
B) Posterior sternoclavicular ligament
C) Costoclavicular ligament
D) Interclavicular ligament

✅ Answer: C - Costoclavicular ligament The costoclavicular ligament (rhomboid ligament) runs between the first rib/costal cartilage and the inferior surface of the medial clavicle. It is the primary restraint against upward and lateral displacement.

Q3. The sternoclavicular joint contains an articular disc. What is its function?

A) Limits movement to rotation only
B) Improves congruence and allows a wider range of movement
C) Prevents all posterior displacement
D) Fuses the joint after age 30

✅ Answer: B - Improves congruence and allows a wider range of movement The fibrocartilaginous disc compensates for the incongruence between the saddle-shaped articular surfaces and effectively divides the joint cavity into two compartments.

Q4. The acromioclavicular (AC) joint is reinforced superiorly by the acromioclavicular ligament. Which additional ligaments, collectively called the coracoclavicular ligaments, provide the strongest suspensory support?

A) Coracohumeral and coracoacromial
B) Trapezoid and conoid ligaments
C) Costoclavicular and conoid ligaments
D) Coracoacromial and trapezoid ligaments

✅ Answer: B - Trapezoid and conoid ligaments The coracoclavicular ligament has two parts: the lateral trapezoid ligament and the medial conoid ligament. Together they suspend the scapula (and upper limb) from the clavicle and are critical in AC joint injuries.

Q5. In a Grade III acromioclavicular joint dislocation, which structure is disrupted?

A) Acromioclavicular ligament only
B) Coracoclavicular ligaments only
C) Both acromioclavicular and coracoclavicular ligaments
D) Glenohumeral joint capsule

✅ Answer: C - Both acromioclavicular and coracoclavicular ligaments Grades I-II involve partial/complete AC ligament injury. Grade III involves complete disruption of both the AC ligament AND the coracoclavicular (trapezoid + conoid) ligaments, causing visible "step deformity."

Q6. The glenohumeral joint has the greatest range of motion of any joint in the body. This mobility comes at the cost of:

A) Increased cartilage thickness
B) Reduced stability
C) Larger articular surface on the glenoid
D) Thicker joint capsule

✅ Answer: B - Reduced stability The glenoid cavity is shallow and covers only about 1/3 of the humeral head. This allows the greatest range of motion in the body but makes it the most commonly dislocated joint.

Q7. Which structure deepens the glenoid cavity and anchors the glenohumeral ligaments?

A) Subacromial bursa
B) Articular disc
C) Glenoid labrum
D) Coracoacromial ligament

✅ Answer: C - Glenoid labrum The fibrocartilaginous glenoid labrum deepens the glenoid cavity by approximately 50%, increases articular contact area, and serves as the primary attachment point for the glenohumeral ligaments and long head of biceps.

Q8. Which direction is the glenohumeral joint most commonly dislocated, and why?

A) Posterior - the posterior capsule is weakest
B) Anterior - the anteroinferior capsule/labrum is the weakest area
C) Superior - the rotator cuff cannot resist upward forces
D) Inferior - gravity pulls the arm down

✅ Answer: B - Anterior (anteroinferior) Approximately 95% of shoulder dislocations are anterior. The anteroinferior capsule and labrum are the weakest areas, vulnerable when the arm is abducted and externally rotated (e.g., throwing). Avulsion of the anteroinferior labrum = Bankart lesion.

GLENOHUMERAL JOINT - LIGAMENTS & CAPSULE (Q9-14)

Q9. The coracohumeral ligament strengthens which aspect of the glenohumeral joint capsule?

A) Inferior
B) Anterior
C) Superior
D) Posterior

✅ Answer: C - Superior The coracohumeral ligament runs from the lateral coracoid process to the greater tuberosity of the humerus, reinforcing the superior capsule and helping prevent inferior subluxation when the arm is at the side.

Q10. The three glenohumeral ligaments (superior, middle, inferior) are thickenings of which structure?

A) The rotator cuff tendons
B) The anterior joint capsule
C) The coracohumeral ligament
D) The posterior capsule

✅ Answer: B - The anterior joint capsule The superior, middle, and inferior glenohumeral ligaments (GHLs) are fibrous thickenings of the anterior capsule. The inferior glenohumeral ligament is the most important stabilizer against anterior dislocation.

Q11. The rotator cuff consists of four muscles. Which one does NOT attach to the greater tuberosity of the humerus?

A) Supraspinatus
B) Infraspinatus
C) Teres minor
D) Subscapularis

✅ Answer: D - Subscapularis Supraspinatus, infraspinatus, and teres minor all insert on the greater tuberosity. Subscapularis inserts on the lesser tuberosity. It is the only rotator cuff muscle that internally rotates the humerus.

Q12. The subacromial (subdeltoid) bursa is clinically important because it lies between which two structures?

A) Coracoid process and the capsule
B) Deltoid/acromion above and the supraspinatus tendon below
C) The biceps tendon and the glenoid labrum
D) The scapula and the posterior capsule

✅ Answer: B - Deltoid/acromion above and the supraspinatus tendon below The subacromial bursa reduces friction between the rotator cuff (especially supraspinatus) and the acromion/deltoid during arm elevation. Impingement syndrome involves compression and inflammation of this bursa and/or the supraspinatus tendon.

Q13. A Hill-Sachs lesion associated with anterior shoulder dislocation is a compression fracture of which part of the humeral head?

A) Anteroinferior
B) Posterosuperior
C) Medial articular surface
D) Greater tuberosity

✅ Answer: B - Posterosuperior When the humeral head dislocates anteriorly, it impacts against the anteroinferior glenoid rim. The posterosuperior humeral head gets "dented" = Hill-Sachs lesion. The glenoid rim lesion = Bankart lesion.

Q14. The long head of biceps brachii tendon runs within the glenohumeral joint. Where does it attach?

A) Coracoid process
B) Supraglenoid tubercle
C) Glenoid labrum only
D) Infraglenoid tubercle

✅ Answer: B - Supraglenoid tubercle The long head of biceps attaches to the supraglenoid tubercle (and blends with the superior glenoid labrum). It passes through the joint cavity within a synovial sheath before entering the bicipital groove of the humerus.

ELBOW JOINT (Q15-22)

Q15. The elbow joint complex involves three separate articulations sharing a common synovial cavity. Which of the following is NOT one of them?

A) Humeroulnar joint (trochlear notch on trochlea)
B) Humeroradial joint (radial head on capitulum)
C) Proximal radioulnar joint
D) Distal radioulnar joint

✅ Answer: D - Distal radioulnar joint The three articulations sharing the elbow synovial cavity are: humeroulnar, humeroradial, and proximal radioulnar joints. The distal radioulnar joint is a separate joint at the wrist.

Q16. The anular ligament of the radius encircles the radial head and attaches to which structure?

A) Lateral epicondyle of humerus anteriorly and posteriorly
B) Anterior and posterior margins of the radial notch of the ulna
C) The coronoid process of ulna and the radial tuberosity
D) The capitulum of the humerus

✅ Answer: B - Anterior and posterior margins of the radial notch of the ulna The anular ligament forms a collar around the radial head, attaching to both margins of the radial notch of the ulna. It holds the radial head against the ulna during pronation/supination without impeding rotation.

Q17. "Pulled elbow" (nursemaid's elbow/radial head subluxation) occurs when the radial head slips out of the anular ligament. This is most common in which age group?

A) Adults over 50 years
B) Teenagers during sports
C) Children under 5 years
D) Newborns

✅ Answer: C - Children under 5 years In young children, the radial head is not yet fully developed and the anular ligament is lax, allowing subluxation with a sharp longitudinal pull on the child's forearm. Treatment is simple supination + compression of the elbow joint.

Q18. The medial (ulnar) collateral ligament of the elbow has three bands. Which band is the strongest and most important for elbow stability?

A) Posterior band
B) Transverse band (Cooper's ligament)
C) Anterior band
D) Oblique band

✅ Answer: C - Anterior band The anterior band of the medial (ulnar) collateral ligament is the strongest component and the primary stabilizer against valgus stress at the elbow. It is commonly injured in overhead throwing athletes ("Tommy John" injury).

Q19. A supracondylar fracture of the humerus is most dangerous because of risk to which structure?

A) Ulnar nerve
B) Radial nerve
C) Brachial artery and median nerve
D) Musculocutaneous nerve

✅ Answer: C - Brachial artery and median nerve The brachial artery and median nerve pass directly anterior to the elbow joint. In a supracondylar fracture, the proximal fragment displaces anteriorly and can lacerate or compress both, leading to Volkmann's ischemic contracture if untreated.

Q20. The carrying angle of the elbow is the valgus angle between the arm and forearm when the elbow is fully extended. The normal carrying angle in females is approximately:

A) 0-5°
B) 5-10°
C) 10-15°
D) 15-25°

✅ Answer: C - 10-15° (females); males ~5-10° The carrying angle is slightly larger in females (10-15°) than males (5-10°). An increased angle = cubitus valgus; decreased/reversed = cubitus varus (gunstock deformity, often from malunited supracondylar fracture).

Q21. Which nerve is at greatest risk during a fracture of the medial epicondyle of the humerus?

A) Median nerve
B) Radial nerve
C) Ulnar nerve
D) Musculocutaneous nerve

✅ Answer: C - Ulnar nerve The ulnar nerve passes directly posterior to the medial epicondyle in the cubital tunnel. Fractures, dislocations, or chronic compression here cause "funny bone" sensation and ulnar nerve palsy (claw hand affecting 4th and 5th digits).

Q22. The elbow joint is primarily innervated by which two nerves?

A) Median and ulnar nerves
B) Radial and musculocutaneous nerves
C) Radial and median nerves
D) Ulnar and musculocutaneous nerves

✅ Answer: B - Radial and musculocutaneous nerves The elbow joint is predominantly innervated by branches of the radial and musculocutaneous nerves, with possible contributions from the ulnar and median nerves.

RADIOULNAR JOINTS & FOREARM (Q23-26)

Q23. Pronation and supination of the forearm occur at which two joints acting together as a single functional unit?

A) Humeroulnar + humeroradial joints
B) Proximal + distal radioulnar joints
C) Radiocarpal + midcarpal joints
D) Proximal radioulnar + radiocarpal joints

✅ Answer: B - Proximal + distal radioulnar joints The proximal and distal radioulnar joints function together as a single pivot ("forearm joint"). The radius rotates around the ulna: in pronation the radius crosses over the ulna; in supination they lie parallel.

Q24. The distal radioulnar joint (DRUJ) is stabilized primarily by which structure?

A) Anular ligament
B) Triangular fibrocartilage complex (TFCC)
C) Palmar radiocarpal ligament
D) Interosseous membrane alone

✅ Answer: B - Triangular fibrocartilage complex (TFCC) The TFCC is the primary stabilizer of the DRUJ. It consists of the articular disc (triangular fibrocartilage), meniscus homologue, and associated ligaments. TFCC tears cause ulnar-sided wrist pain and DRUJ instability.

Q25. The interosseous membrane of the forearm primarily transmits forces from the hand in which direction?

A) From radius to ulna (proximally)
B) From ulna to radius (distally)
C) Equally in both directions
D) Only during supination

✅ Answer: A - From radius to ulna (proximally) About 80% of axial load through the forearm is transmitted through the radius (via the radiocarpal joint). The interosseous membrane transfers this force from the radius to the ulna, distributing load more evenly up the forearm.

Q26. A fall on an outstretched hand (FOOSH) can cause a Colles' fracture. This involves fracture of the distal radius with which displacement?

A) Volar (palmar) displacement - "garden spade" deformity
B) Dorsal displacement + radial deviation - "dinner fork" deformity
C) Ulnar deviation + volar displacement
D) Proximal displacement only

✅ Answer: B - Dorsal displacement + radial deviation - "dinner fork" deformity Colles' fracture: distal radius fracture within 2 cm of the wrist with dorsal displacement and angulation + radial shortening/deviation = classic "dinner fork" deformity. Most common fracture in adults over 50.

WRIST & CARPAL JOINTS (Q27-32)

Q27. The radiocarpal (wrist) joint is formed between the distal radius + articular disc above, and which carpal bones below?

A) Scaphoid, lunate, capitate
B) Scaphoid, lunate, triquetrum
C) Lunate, triquetrum, pisiform
D) Scaphoid, trapezium, trapezoid

✅ Answer: B - Scaphoid, lunate, triquetrum The proximal row of carpals (scaphoid, lunate, triquetrum) forms the convex surface that articulates with the concave surface of the distal radius and articular disc (TFCC) at the radiocarpal joint. The pisiform is a sesamoid bone and does not contribute.

Q28. At the wrist joint, the range of adduction (ulnar deviation) is greater or lesser than abduction (radial deviation)?

A) Lesser - because the radial styloid extends more distally
B) Greater - because the radial styloid extends more distally
C) Equal in both directions
D) Abduction is greater because of the TFCC

✅ Answer: B - Greater (ulnar deviation > radial deviation) The radial styloid process extends more distally than the ulnar styloid process. This bony block limits radial deviation (abduction), meaning the hand can adduct (ulnar deviate) to a greater degree than it can abduct (radially deviate).

Q29. The most commonly fractured carpal bone following a fall on an outstretched hand is:

A) Lunate
B) Triquetrum
C) Scaphoid
D) Capitate

✅ Answer: C - Scaphoid The scaphoid is the most commonly fractured carpal bone. The blood supply enters distally, so fractures of the proximal pole risk avascular necrosis (AVN) if untreated. A key clinical sign is tenderness in the anatomical snuffbox.

Q30. The midcarpal joint lies between the proximal and distal rows of carpal bones. Which movement does it primarily contribute to?

A) Pronation and supination
B) Extension more than flexion
C) Circumduction only
D) Adduction only

✅ Answer: B - Extension more than flexion The midcarpal joint contributes significantly to wrist extension (roughly 50% of total extension occurs here). The radiocarpal joint contributes more to flexion and radial/ulnar deviation.

Q31. The carpometacarpal (CMC) joint of the thumb is classified as a:

A) Hinge joint
B) Condylar joint
C) Saddle joint
D) Pivot joint

✅ Answer: C - Saddle joint The first CMC joint (between metacarpal I and trapezium) is a saddle joint. This gives the thumb its unique range of motion: flexion, extension, abduction, adduction, rotation, and circumduction - essential for opposition.

Q32. The metacarpophalangeal (MCP) joints are classified as which type of synovial joint?

A) Hinge joints allowing only flexion/extension
B) Condylar joints allowing flexion, extension, abduction, adduction, and circumduction
C) Saddle joints
D) Plane joints

✅ Answer: B - Condylar joints MCP joints are condylar (ellipsoid) joints. They allow flexion, extension, abduction, adduction, and circumduction, but only limited rotation. They are reinforced by palmar ligaments and collateral ligaments (taut in flexion, lax in extension).

FINGER JOINTS & CLINICAL (Q33-40)

Q33. The collateral ligaments of the MCP joints are taut in flexion and lax in extension. What is the clinical implication of this?

A) Splint the MCP joints in extension to prevent stiffness
B) Splint the MCP joints in flexion to prevent collateral ligament shortening and stiffness
C) MCP joints should never be immobilized
D) Extension splinting prevents swan neck deformity

✅ Answer: B - Splint MCP joints in flexion Because collateral ligaments are lax in extension, immobilizing the MCP in extension allows the ligaments to shorten, causing stiffness. MCP joints should be splinted in 70-90° flexion to keep collateral ligaments taut and prevent contracture.

Q34. The interphalangeal (IP) joints of the fingers are classified as:

A) Condylar joints
B) Saddle joints
C) Hinge joints
D) Ball and socket joints

✅ Answer: C - Hinge joints Both the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints are pure hinge joints, allowing only flexion and extension. They are stabilized by strong collateral ligaments and a volar (palmar) plate.

Q35. The volar plate (palmar ligament) of the PIP joint prevents which deformity when it is disrupted?

A) Mallet finger
B) Swan neck deformity
C) Boutonnière deformity
D) Dupuytren's contracture

✅ Answer: B - Swan neck deformity The volar plate prevents PIP hyperextension. If disrupted (volar plate injury or rheumatoid disease), the PIP joint hyperextends = swan neck deformity (PIP hyperextension + DIP flexion). Boutonnière = PIP flexion + DIP hyperextension (central slip disruption).

Q36. Which carpal bone articulates with the distal end of the ulna via the articular disc (TFCC) rather than directly?

A) Lunate
B) Triquetrum
C) Pisiform
D) The ulna does not contribute to any carpal joint

✅ Answer: D (refined: the ulna does NOT directly contact any carpal bone) The distal ulna is separated from the carpals (triquetrum and lunate) by the articular disc (TFCC). The TFCC "bridges" the gap, so the ulna has no direct bony articulation with the carpal bones at the wrist joint.

Q37. The pisiform bone articulates with which carpal bone, making it a sesamoid-type bone?

A) Hamate
B) Triquetrum
C) Lunate
D) Capitate

✅ Answer: B - Triquetrum The pisiform articulates only with the triquetrum (pisotriquetral joint). It is a sesamoid bone embedded in the flexor carpi ulnaris tendon. The ulnar nerve and artery pass just lateral to it in Guyon's canal.

Q38. In rheumatoid arthritis, the wrist typically deviates in which direction due to ligamentous laxity and tendon imbalance?

A) Radial deviation of the wrist; radial deviation of the fingers
B) Ulnar deviation of the wrist; ulnar deviation of the fingers
C) Ulnar deviation of the wrist; radial deviation of the fingers
D) Radial deviation of the wrist; ulnar deviation of the fingers

✅ Answer: C - Ulnar deviation of the wrist; radial deviation of the fingers Classic "zigzag" deformity of rheumatoid arthritis: the wrist deviates ulnarly while the MCP joints and fingers deviate radially. This creates a characteristic zigzag or "Z-deformity" of the hand.

Q39. Which ligament of the wrist is most commonly implicated in scapholunate dissociation?

A) Palmar radiocarpal ligament
B) Scapholunate interosseous ligament
C) Ulnocarpal ligament
D) Radial collateral ligament of the wrist

✅ Answer: B - Scapholunate interosseous ligament Scapholunate dissociation results from disruption of the scapholunate interosseous ligament. On X-ray, a gap > 3mm between scaphoid and lunate = Terry-Thomas sign. The scaphoid tilts into flexion (DISI deformity on lateral X-ray).

Q40. A boxer's fracture involves fracture of the neck of which metacarpal, and which direction does the metacarpal head angulate?

A) 2nd metacarpal neck; dorsally
B) 5th metacarpal neck; volarly (palmarly)
C) 5th metacarpal neck; dorsally
D) 4th metacarpal neck; volarly

✅ Answer: B - 5th metacarpal neck; volarly (palmarly) A boxer's fracture is a fracture of the neck of the 5th (occasionally 4th) metacarpal, typically from punching with a closed fist. The metacarpal head angulates volarly (palmarly) due to the pull of the intrinsic muscles. The 5th MCP joint appears flattened on examination.

38 MCQ Revision Test - Muscles, Blood Supply & Nerve Supply of the Leg

Source: Gray's Anatomy for Students, Chapter 6 Try to answer each question before reading the answer!

SECTION A - POSTERIOR COMPARTMENT: SUPERFICIAL GROUP (Q1-8)

Q1. How many compartments does the leg have, and how many muscles are in the posterior compartment in total?

A) 2 compartments; 6 muscles
B) 3 compartments; 7 muscles
C) 3 compartments; 8 muscles
D) 4 compartments; 9 muscles

✅ Answer: B - 3 compartments; 7 muscles The leg has 3 compartments: anterior (4 muscles), lateral (2 muscles), and posterior (7 muscles - 3 superficial + 4 deep). All posterior compartment muscles are innervated by the tibial nerve.

Q2. The gastrocnemius muscle originates from two heads. Where exactly does the medial head arise?

A) The medial surface of the tibial shaft
B) A roughening on the posterior distal femur, just behind the adductor tubercle and above the medial condyle
C) The posterior surface of the medial femoral condyle directly
D) The posterior capsule of the knee joint

✅ Answer: B - Posterior distal femur, behind the adductor tubercle, above the medial condyle articular surface The medial head is proximal to the medial condyle articular surface. The lateral head originates from a distinct facet on the upper lateral surface of the lateral femoral condyle.

Q3. The gastrocnemius and soleus muscles join to form the calcaneal (Achilles) tendon. Which additional muscle also contributes its tendon to this structure?

A) Popliteus
B) Plantaris
C) Tibialis posterior
D) Flexor digitorum longus

✅ Answer: B - Plantaris Plantaris has a small proximal muscle belly and a very long thin tendon that descends between gastrocnemius and soleus and fuses with the medial side of the calcaneal tendon near the calcaneus.

Q4. The soleus muscle is a powerful plantarflexor but cannot flex the knee. Why?

A) It is innervated by a different nerve than gastrocnemius
B) It originates from the tibia and fibula, not the femur - so it does not cross the knee joint
C) Its insertion on the calcaneus is too distal
D) It is too deep to generate enough force

✅ Answer: B - It originates from the tibia and fibula, not the femur Soleus originates from the posterior head of the fibula, the soleal line of the tibia, and the tendinous arch between them. Because it does not cross the knee joint, it cannot flex it. Gastrocnemius and plantaris both originate from the femur and therefore can flex the knee.

Q5. The soleus muscle is considered particularly important for venous return from the lower limb. Why?

A) It compresses the posterior tibial vein during contraction, acting as a "peripheral heart"
B) It drains directly into the great saphenous vein
C) It lies superficial to the popliteal vein
D) It contains the largest venous sinuses in the body

✅ Answer: A - It acts as a "peripheral heart" by compressing the deep veins during contraction The soleus muscle contains large venous sinuses. Contraction during walking compresses these sinuses and pumps blood proximally - this is the "soleal pump" or "peripheral heart," critical for preventing DVT.

Q6. Which nerve innervates ALL three muscles of the superficial posterior compartment?

A) Common fibular nerve
B) Superficial fibular nerve
C) Sural nerve
D) Tibial nerve

✅ Answer: D - Tibial nerve Gastrocnemius, plantaris, and soleus are all innervated by the tibial nerve. The branches to these muscles originate high in the leg, between the two heads of gastrocnemius, in the distal popliteal fossa region.

Q7. The plantaris muscle has a very long thin tendon. What is the clinical significance of this muscle?

A) It is the primary plantarflexor
B) It is absent in about 7-10% of people and its tendon is commonly harvested for tendon grafts
C) It is the sole nerve supply to the calcaneus
D) Its rupture causes Achilles tendon avulsion

✅ Answer: B - It is absent in ~7-10% of people and its tendon is used for tendon grafts Plantaris is a vestigial muscle with minimal functional importance. It is absent in a significant minority of the population, and its long tendon is sometimes harvested for reconstructive tendon surgery (e.g. hand surgery, Achilles reconstruction).

Q8. The Thompson test is used to assess the integrity of the Achilles tendon. What does a positive test indicate?

A) The soleus is torn
B) The gastrocnemius medial head has avulsed from the femur
C) The Achilles tendon is completely ruptured
D) The plantaris tendon is torn

✅ Answer: C - Complete rupture of the Achilles (calcaneal) tendon In the Thompson test, the patient kneels or lies prone and the calf is squeezed. Normally, plantarflexion occurs (negative). If the Achilles tendon is completely ruptured, squeezing the calf produces NO foot movement = positive Thompson test.

SECTION B - POSTERIOR COMPARTMENT: DEEP GROUP (Q9-16)

Q9. How many muscles are in the deep posterior compartment of the leg?

A) 3
B) 4
C) 5
D) 6

✅ Answer: B - 4 The deep posterior compartment contains 4 muscles: popliteus, tibialis posterior, flexor digitorum longus (FDL), and flexor hallucis longus (FHL). All are innervated by the tibial nerve.

Q10. Which deep posterior compartment muscle is responsible for "unlocking" the fully extended knee joint?

A) Plantaris
B) Tibialis posterior
C) Popliteus
D) Flexor hallucis longus

✅ Answer: C - Popliteus The fully extended knee is "locked" in a close-packed position by lateral rotation of the femur on the tibia. Popliteus medially rotates the femur on the fixed tibia (or laterally rotates the tibia on the femur) to unlock the knee and allow flexion.

Q11. The tibialis posterior is the deepest muscle in the posterior compartment. What is its primary function?

A) Plantarflexion only
B) Inversion and plantarflexion of the foot; dynamic support of the medial longitudinal arch
C) Eversion and dorsiflexion
D) Flexion of all toes

✅ Answer: B - Inversion, plantarflexion, and support of the medial arch Tibialis posterior is the primary invertor of the foot. It also plantarflexes and is a key dynamic supporter of the medial longitudinal arch. Its tendon passes behind the medial malleolus (tarsal tunnel). Dysfunction causes adult-acquired flatfoot.

Q12. Which mnemonic helps remember the order of structures passing through the tarsal tunnel (medial to the medial malleolus)?

A) Tom Dick Harry
B) Tom Dick And Nervous Harry
C) Never Forget To Dorsiflex
D) Sally Has Four Digits

✅ Answer: B - Tom Dick And Nervous Harry From anterior to posterior in the tarsal tunnel:

Tibialis posterior
Digitorum longus (FDL)
Artery (posterior tibial a. + vein)
Nerve (tibial nerve)
Hallucis longus (FHL)

Q13. The flexor hallucis longus (FHL) originates from the posterior fibula and inserts on which structure?

A) The base of the proximal phalanx of the great toe
B) The plantar surface of the base of the distal phalanx of the great toe
C) The medial cuneiform
D) The base of metatarsal I

✅ Answer: B - Plantar surface of the base of the distal phalanx of the great toe FHL flexes the great toe at both the MTP and IP joints, and assists plantarflexion of the foot. It is innervated by the tibial nerve (S2, S3). Its tendon passes through the tarsal tunnel as the most posterior structure.

Q14. Flexor digitorum longus (FDL) divides into how many tendons in the sole, and what does it insert into?

A) 2 tendons; middle phalanges of toes II-III
B) 4 tendons; distal phalanges of the lateral four toes (II-V)
C) 5 tendons; proximal phalanges of all five toes
D) 4 tendons; middle phalanges of toes II-V

✅ Answer: B - 4 tendons; distal phalanges of toes II-V (lateral four toes) FDL flexes the distal phalanges of the lateral four toes and assists plantarflexion. In the sole, it crosses with FHL (Master knot of Henry) before dividing into 4 tendons.

Q15. Where do the tibial nerve branches to the deep posterior compartment muscles originate?

A) In the popliteal fossa, above the knee
B) Deep to the soleus muscle in the upper half of the leg
C) In the tarsal tunnel, just above the medial malleolus
D) From the sural nerve

✅ Answer: B - Deep to the soleus muscle in the upper half of the leg Branches to the superficial group arise high between the gastrocnemius heads. Branches to the deep group (tibialis posterior, FHL, FDL) originate from the tibial nerve deep to soleus in the upper half of the leg.

Q16. Tibial nerve compression in the tarsal tunnel (tarsal tunnel syndrome) causes symptoms in which distribution?

A) Dorsum of the foot and 1st web space
B) Lateral border of the foot only
C) Sole of the foot and toes (medial and lateral plantar nerve distributions)
D) Posterior calf and heel

✅ Answer: C - Sole of the foot and toes (medial + lateral plantar nerve territories) The tibial nerve divides in the tarsal tunnel into medial and lateral plantar nerves, which supply the sole. Compression causes burning/tingling in the sole and toes (Tinel's sign positive over the tarsal tunnel).

SECTION C - LATERAL COMPARTMENT (Q17-22)

Q17. How many muscles are in the lateral compartment of the leg, and what is their primary action?

A) 2 muscles; inversion of the foot
B) 3 muscles; eversion and plantarflexion
C) 2 muscles; eversion of the foot
D) 2 muscles; dorsiflexion and eversion

✅ Answer: C - 2 muscles; eversion of the foot Fibularis longus and fibularis brevis are the only two muscles in the lateral compartment. Both evert the foot (turn the sole outward) and both are innervated by the superficial fibular nerve.

Q18. Where does the fibularis brevis insert?

A) Medial cuneiform and base of metatarsal I
B) Plantar surface of the base of metatarsal I and medial cuneiform
C) Base (styloid process) of metatarsal V
D) Cuboid bone

✅ Answer: C - Base (styloid process) of metatarsal V Fibularis brevis inserts on the lateral side of the base of metatarsal V. A sudden forceful inversion injury can avulse this insertion - an avulsion fracture at the base of the 5th metatarsal is very commonly seen on foot X-rays.

Q19. The fibularis longus has a long tendon that crosses under the foot obliquely. Where does it finally insert?

A) Lateral surface of the cuboid
B) Medial cuneiform and base of metatarsal I
C) Base of metatarsal V
D) Navicular tuberosity

✅ Answer: B - Medial cuneiform and base of metatarsal I This is a key exam fact. Despite originating laterally, fibularis longus passes under the foot in a groove on the cuboid and crosses to the medial side, inserting on the medial cuneiform and base of metatarsal I. This makes it an important supporter of the transverse arch of the foot.

Q20. Which nerve innervates both muscles of the lateral compartment?

A) Deep fibular nerve
B) Common fibular nerve directly
C) Superficial fibular nerve
D) Sural nerve

✅ Answer: C - Superficial fibular nerve The superficial fibular nerve is one of the two terminal branches of the common fibular nerve (at the neck of the fibula). It innervates fibularis longus and brevis, then pierces the deep fascia in the lower leg to supply cutaneous sensation over the dorsum of the foot (except the 1st web space).

Q21. The common fibular nerve wraps around which bony landmark and is most vulnerable here?

A) Posterior to the medial malleolus
B) Anterior to the lateral malleolus
C) The neck of the fibula
D) The proximal tibiofibular joint

✅ Answer: C - The neck of the fibula The common fibular nerve is the most commonly injured nerve in the lower limb. It passes around the lateral aspect of the fibular neck just beneath the skin, making it vulnerable to fractures, tight plaster casts, prolonged leg crossing, and direct blows.

Q22. A patient with a common fibular nerve injury at the fibular neck would present with which combination of deficits?

A) Loss of plantarflexion and inversion only
B) Foot drop (loss of dorsiflexion + toe extension) + loss of eversion + sensory loss over the dorsum of the foot and lateral leg
C) Loss of inversion only
D) Loss of toe flexion and plantar sensation

✅ Answer: B - Foot drop + loss of eversion + sensory loss over dorsum of foot and lateral leg The common fibular nerve supplies both the anterior compartment (via deep fibular n.) and lateral compartment (via superficial fibular n.). Injury causes:

Loss of dorsiflexion (anterior compartment) = foot drop
Loss of eversion (lateral compartment)
Sensory loss over the lateral leg and dorsum of the foot

SECTION D - ANTERIOR COMPARTMENT (Q23-29)

Q23. Which four muscles are found in the anterior compartment of the leg?

A) Tibialis anterior, FDL, FHL, EHL
B) Tibialis anterior, EHL, EDL, fibularis tertius
C) Tibialis anterior, EHL, EDL, tibialis posterior
D) EHL, EDL, fibularis longus, tibialis anterior

✅ Answer: B - Tibialis anterior, extensor hallucis longus (EHL), extensor digitorum longus (EDL), fibularis tertius All four muscles dorsiflex the foot. Tibialis anterior also inverts; fibularis tertius also everts. All are innervated by the deep fibular nerve (L4, L5).

Q24. Tibialis anterior is innervated by the deep fibular nerve at spinal root levels L4, L5. Where does it insert?

A) Lateral surface of the cuboid
B) Medial and inferior surfaces of the medial cuneiform and adjacent base of metatarsal I
C) Navicular tuberosity
D) Dorsal surface of the base of the proximal phalanx of the great toe

✅ Answer: B - Medial and inferior surfaces of the medial cuneiform and adjacent base of metatarsal I Tibialis anterior is the largest and most medial muscle in the anterior compartment. Its insertion makes it an invertor AND dorsiflexor. It is also a dynamic supporter of the medial arch of the foot.

Q25. The extensor hallucis longus (EHL) inserts on which structure?

A) Proximal phalanx of the great toe (dorsal surface)
B) Middle phalanx of the great toe
C) Dorsal surface of the base of the distal phalanx of the great toe
D) Head of metatarsal I

✅ Answer: C - Dorsal surface of the base of the distal phalanx of the great toe EHL extends the great toe (at both MTP and IP joints) and dorsiflexes the foot. It is innervated by the deep fibular nerve (L5, S1). Its tendon is easily visible on the dorsum of the foot when the great toe is extended.

Q26. Extensor digitorum longus (EDL) inserts via extensor (dorsal digital) expansions onto which structures?

A) Bases of proximal phalanges of toes II-V only
B) Bases of middle and distal phalanges of the lateral four toes (II-V)
C) Distal phalanges of all five toes
D) Bases of middle phalanges of toes I-IV

✅ Answer: B - Bases of the middle and distal phalanges of toes II-V EDL extends the lateral four toes via extensor (dorsal digital) expansions (analogous to the extensor expansion in the hand). It also dorsiflexes the foot.

Q27. Fibularis tertius is considered a part of which muscle, which it separates from distally?

A) Fibularis longus
B) Extensor hallucis longus
C) Extensor digitorum longus
D) Tibialis anterior

✅ Answer: C - Extensor digitorum longus Fibularis tertius is a partially separate distal part of EDL. It inserts on the dorsomedial surface of the base of metatarsal V and is the only muscle in the anterior compartment that everts the foot (as well as dorsiflexing).

Q28. The deep fibular nerve originates in which compartment of the leg?

A) Posterior compartment, from the tibial nerve
B) Lateral compartment, as one of the two terminal branches of the common fibular nerve
C) Anterior compartment, directly from the sciatic nerve
D) Directly from the lumbosacral plexus

✅ Answer: B - Lateral compartment, as a terminal branch of the common fibular nerve The common fibular nerve divides at the fibular neck into: (1) deep fibular nerve - passes through the intermuscular septum into the anterior compartment; and (2) superficial fibular nerve - stays in the lateral compartment. The deep fibular nerve then travels with the anterior tibial artery.

Q29. In the foot, the deep fibular nerve supplies cutaneous sensation to which specific area?

A) Entire dorsum of the foot
B) Lateral border of the foot
C) The first web space (between great toe and 2nd toe)
D) Sole of the foot

✅ Answer: C - The first web space (between the great toe and 2nd toe) The deep fibular nerve continues onto the dorsum of the foot where it supplies the extensor digitorum brevis, contributes to the first two dorsal interossei, and gives cutaneous supply only to the 1st web space. The rest of the dorsum is supplied by the superficial fibular nerve.

SECTION E - BLOOD SUPPLY OF THE LEG (Q30-38)

Q30. The popliteal artery terminates by dividing into two named arteries. Where does this division occur?

A) At the level of the knee joint
B) Under the tendinous arch of the soleus, where it enters the deep posterior compartment
C) At the upper border of popliteus
D) Behind the medial malleolus

✅ Answer: B - Under the tendinous arch of the soleus, entering the deep posterior compartment The popliteal artery passes between gastrocnemius and popliteus, then passes under the soleal arch, entering the deep posterior compartment where it immediately divides into the anterior tibial artery and posterior tibial artery.

Q31. How does the anterior tibial artery enter the anterior compartment of the leg?

A) It passes superficial to the extensor retinaculum
B) It passes through an aperture (opening) in the upper part of the interosseous membrane
C) It winds around the neck of the fibula
D) It passes through the soleus muscle

✅ Answer: B - Through an aperture in the upper part of the interosseous membrane The anterior tibial artery is the only artery that actively crosses from the posterior to the anterior compartment by passing through the aperture in the superior interosseous membrane. It then descends on the interosseous membrane with the deep fibular nerve.

Q32. The anterior tibial artery continues distally onto the dorsum of the foot under which name?

A) Plantar arch
B) Medial plantar artery
C) Dorsalis pedis artery
D) Lateral tarsal artery

✅ Answer: C - Dorsalis pedis artery As the anterior tibial artery passes anterior to the distal end of the tibia and the ankle joint, it becomes the dorsalis pedis artery. This artery is palpated in the 1st interosseous space lateral to the EHL tendon - an important clinical pulse check.

Q33. The posterior tibial artery is a direct continuation of the popliteal artery. It supplies which compartments?

A) Anterior and lateral compartments only
B) Posterior and lateral compartments of the leg, then continues into the sole
C) Posterior compartment only
D) All three compartments equally

✅ Answer: B - Posterior and lateral compartments, then the sole of the foot The posterior tibial artery descends through the deep posterior compartment, gives off the fibular (peroneal) artery, sends branches to the lateral compartment via the fibular artery, passes through the tarsal tunnel behind the medial malleolus, and enters the sole where it divides into medial and lateral plantar arteries.

Q34. The fibular (peroneal) artery is the largest branch of the posterior tibial artery. It descends along which structure?

A) The medial border of the tibia
B) The lateral side of the posterior compartment, adjacent to the medial crest on the posterior surface of the fibula
C) The posterior surface of the popliteus
D) The interosseous membrane anteriorly

✅ Answer: B - Lateral side of the posterior compartment, along the medial crest of the fibula The fibular artery parallels the posterior tibial artery but on the lateral side. It travels between tibialis posterior and FHL, along the medial crest on the posterior fibula. It supplies adjacent muscles, the fibula itself (periosteal branches), and sends perforating branches to the lateral compartment.

Q35. A perforating branch of the fibular artery passes through the inferior interosseous membrane to anastomose with which artery?

A) Dorsalis pedis artery
B) A branch of the anterior tibial artery
C) The circumflex fibular artery
D) The medial plantar artery

✅ Answer: B - A branch of the anterior tibial artery Distally in the leg, the fibular artery sends a perforating branch anteriorly through the inferior aperture of the interosseous membrane. This branch anastomoses with the anterior tibial artery, creating an important collateral connection between the compartments.

Q36. Where is the posterior tibial artery palpated clinically?

A) Over the fibular head
B) In the first interosseous space lateral to EHL
C) Posterior to the medial malleolus
D) In the popliteal fossa

✅ Answer: C - Posterior to the medial malleolus The posterior tibial pulse is felt halfway between the medial malleolus and the Achilles tendon (in the tarsal tunnel). It is one of the two key pedal pulses checked in peripheral vascular disease (the other being dorsalis pedis).

Q37. The sural nerve is a cutaneous nerve. Which nerve roots contribute to it, and from where does it originate?

A) L4-L5; from the deep fibular nerve
B) L5-S1; from the superficial fibular nerve
C) S1-S2; from the tibial nerve, with a communicating branch from the common fibular nerve
D) L2-L3; from the femoral nerve

✅ Answer: C - S1-S2; from the tibial nerve (medial sural cutaneous), joined by a branch from the common fibular nerve The sural nerve originates between the two gastrocnemius heads from the tibial nerve (medial sural cutaneous nerve). In the middle of the leg, it is joined by the sural communicating branch of the common fibular nerve. It pierces the deep fascia and supplies the lower posterolateral leg, lateral malleolus, and lateral foot/little toe.

Q38. In a patient with poorly controlled diabetes, which two pedal pulses are routinely assessed as part of the vascular examination of the foot, and which arteries produce them?

A) Anterior tibial pulse + posterior tibial pulse
B) Dorsalis pedis pulse (anterior tibial a.) + posterior tibial pulse (posterior tibial a.)
C) Fibular pulse + posterior tibial pulse
D) Popliteal pulse + dorsalis pedis pulse

✅ Answer: B - Dorsalis pedis (continuation of anterior tibial a.) + posterior tibial artery pulse Both pedal pulses must be assessed in diabetic foot examination and peripheral vascular disease screening. The dorsalis pedis is felt in the first interosseous space lateral to the EHL tendon. The posterior tibial pulse is felt posterior to the medial malleolus. Absence of either indicates significant peripheral arterial disease.
