I now have comprehensive information from Gray's Anatomy for Students to provide a thorough answer. Let me compile the complete list.

Joints of the Upper Limb

Overview by Region

1. Shoulder Girdle Joints

1.1 Sternoclavicular Joint

Feature	Detail
Type	Synovial — saddle joint (with an articular disc inside, dividing it into two compartments)
Articulation	Proximal end of clavicle ↔ clavicular notch of manubrium sterni + 1st costal cartilage
Movements	Elevation, depression, protraction, retraction, rotation of clavicle
Key ligaments	Anterior/posterior sternoclavicular, interclavicular, costoclavicular ligaments

Despite its saddle shape, the articular disc makes it functionally versatile — the only synovial joint between the upper limb and the axial skeleton.

1.2 Acromioclavicular Joint

Feature	Detail
Type	Synovial — plane (gliding) joint
Articulation	Acromial end of clavicle ↔ medial facet of acromion of scapula
Movements	Anteroposterior, vertical gliding + some axial rotation
Key ligaments	Acromioclavicular ligament (superior); coracoclavicular ligament (trapezoid + conoid — the main weight-bearing support)

2. Shoulder Joint

2.1 Glenohumeral Joint

Feature	Detail
Type	Synovial — ball-and-socket joint (multiaxial)
Articulation	Head of humerus ↔ glenoid cavity of scapula (deepened by fibrocartilaginous glenoid labrum)
Movements	Flexion, extension, abduction, adduction, medial & lateral rotation, circumduction
Stability	Rotator cuff (SITS: supraspinatus, infraspinatus, teres minor, subscapularis) + long head of biceps brachii + coracoacromial arch
Key ligaments	Glenohumeral ligaments (superior, middle, inferior), coracohumeral, transverse humeral

3. Elbow Joint (Complex — three articulations in a single synovial cavity)

3.1 Humeroulnar Joint

Feature	Detail
Type	Synovial — hinge joint
Articulation	Trochlear notch of ulna ↔ trochlea of humerus
Movements	Flexion and extension

3.2 Humeroradial (Radiohumeral) Joint

Feature	Detail
Type	Synovial — hinge joint (also participates in pivot)
Articulation	Head of radius ↔ capitulum of humerus
Movements	Flexion/extension + pronation/supination

3.3 Proximal Radioulnar Joint

Feature	Detail
Type	Synovial — pivot joint
Articulation	Head of radius ↔ radial notch of ulna (held by annular ligament)
Movements	Pronation and supination

All three share a common synovial cavity with articular surfaces covered in hyaline cartilage. Ligaments: medial (ulnar) collateral and lateral (radial) collateral.

4. Forearm

4.1 Distal Radioulnar Joint

Feature	Detail
Type	Synovial — pivot joint
Articulation	Head of ulna ↔ ulnar notch of radius
Movements	Pronation and supination (with proximal radioulnar joint)
Note	Separated from wrist joint by the articular disc (triangular fibrocartilage complex, TFCC)

4.2 Interosseous Membrane (Radioulnar Syndesmosis)

Feature	Detail
Type	Fibrous joint (syndesmosis)
Role	Binds radius and ulna along their shafts; transmits force; provides attachment for muscles

5. Wrist

5.1 Radiocarpal (Wrist) Joint

Feature	Detail
Type	Synovial — ellipsoid (condyloid) joint
Articulation	Distal radius + articular disc ↔ scaphoid, lunate, triquetrum (convex oval surface)
Movements	Flexion, extension, abduction (radial deviation), adduction (ulnar deviation)
Key ligaments	Palmar & dorsal radiocarpal, palmar ulnocarpal, radial & ulnar collateral ligaments

6. Carpal Region

6.1 Intercarpal Joints (Midcarpal Joint)

Feature	Detail
Type	Synovial — plane (gliding) joints (sharing a common cavity)
Articulation	Between the 8 carpal bones (proximal row ↔ distal row + between individual bones within rows)
Movements	Limited gliding; contributes to flexion, extension, abduction, adduction — especially extension

7. Hand

7.1 Carpometacarpal (CMC) Joints

Joint	Type	Movements
CMC of thumb (metacarpal I ↔ trapezium)	Synovial — saddle joint	Flexion, extension, abduction, adduction, rotation, circumduction — wide mobility
CMC of fingers (metacarpals II–V ↔ distal carpal bones)	Synovial — plane (gliding) joints	Limited gliding; increases from 2nd → 5th digit

7.2 Metacarpophalangeal (MCP) Joints

Feature	Detail
Type	Synovial — condylar (ellipsoid) joints
Articulation	Head of metacarpal ↔ base of proximal phalanx
Movements	Flexion, extension, abduction, adduction, circumduction, limited rotation
Ligaments	Palmar ligament + medial and lateral collateral ligaments; deep transverse metacarpal ligaments link fingers II–V together

7.3 Interphalangeal (IP) Joints

Feature	Detail
Type	Synovial — hinge joints
Subtypes	Proximal interphalangeal (PIP) + Distal interphalangeal (DIP) joints for fingers; Interphalangeal joint of thumb
Movements	Flexion and extension only
Ligaments	Palmar ligament + collateral ligaments
