best YouTube video thyroid gland anatomy physiology study

Here are some great YouTube videos to study the thyroid gland, depending on what angle you want to approach it from:

1. Thyroid Overview - Endocrinology (Prof. Zach Murphy)

Watch on YouTube
  • Best for: Physiology & big-picture overview
  • Covers structure, hormones (T3/T4), feedback loops, and clinical relevance
  • Clear lecture style, good for medical/nursing students

2. Thyroid Gland Anatomy - Armando Hasudungan

Watch on YouTube
  • Best for: Detailed anatomy
  • Covers embryology, blood supply, nerve supply, and relations
  • Armando's hand-drawn illustrations are excellent for visual learners

3. Thyroid and Parathyroid Glands (Anatomy + Histology)

Watch on YouTube
  • Best for: Gross + microscopic anatomy combined
  • Includes histological features of follicular cells, parafollicular cells
  • Good if you need both macro and micro in one sitting

4. Thyroid Gland Anatomy (Short Overview)

Watch on YouTube
  • Best for: Quick revision
  • Short and focused if you just need a refresher
My recommendation: Start with Armando Hasudungan's video for anatomy, then follow it up with Zach Murphy's physiology overview - together they cover the thyroid comprehensively for exams. If you need histology too, add the third video to your playlist.
Would you like me to also pull up textbook content on any specific aspect (anatomy, hormones, disorders, etc.)?

I have rich, textbook-sourced data from Gray's Anatomy for Students and Cummings Otolaryngology. Here is the quiz:

Muscles of Mastication - 10 Question Quiz

Q1. Which four muscles are classically considered the primary muscles of mastication?
Show Answer
Masseter, Temporalis, Medial pterygoid, and Lateral pterygoid. All are innervated by the mandibular nerve (V3).
- Gray's Anatomy for Students, Table 8.11
Q2. The masseter muscle originates from the zygomatic arch. Where does it insert, and what is its primary function?
Show Answer
It inserts on the lateral surface of the ramus of the mandible. Its primary function is elevation (and protrusion) of the mandible.
- Gray's Anatomy for Students, Table 8.11
Q3. The temporalis muscle is unique among jaw-closers because it can both elevate AND retract the mandible. What is its insertion, and which part is responsible for retraction?
Show Answer
It inserts on the coronoid process of the mandible and anterior margin of the ramus. The posterior fibers are responsible for retraction; the anterior/middle fibers elevate.
- Cummings Otolaryngology, Table 92.1
Q4. All four primary muscles of mastication share the same nerve supply. Name the nerve and its parent trunk.
Show Answer
They are all innervated by the mandibular nerve (V3), the third division of the trigeminal nerve (CN V). Specific branches include the masseteric nerve, deep temporal nerves, and nerves to the medial and lateral pterygoids.
- Gray's Anatomy for Students, Table 8.11
Q5. The lateral pterygoid has two heads with different functions. What does each head do?
Show Answer
  • Superior head - elevation and protrusion of the mandible
  • Inferior head - depression and lateral displacement of the mandible
The inferior head is the main driver of jaw opening (along with gravity), while the superior head works with the other closers.
- Cummings Otolaryngology, Ch. 86
Q6. Which muscle inserts on the medial surface of the angle of the mandible, and what movements does it produce?
Show Answer
The medial pterygoid. It produces elevation, protrusion, and lateral (side-to-side) movements of the mandible. Along with the masseter, it forms a muscular sling around the mandibular angle.
- Cummings Otolaryngology, Table 92.1
Q7. Which three muscles are responsible for depression (opening) of the mandible, and what nerve innervates the mylohyoid?
Show Answer
The jaw-opening muscles are the digastric (anterior belly), mylohyoid, and geniohyoid. The mylohyoid is innervated by the nerve to mylohyoid, a branch of the inferior alveolar nerve (V3).
- Cummings Otolaryngology, Table 92.1
Q8. A patient presents with inability to protrude the jaw and difficulty chewing side-to-side. Damage to which muscle is most likely responsible?
Show Answer
The lateral pterygoid. It is the primary muscle for protrusion and lateral (grinding) movements. Bilateral damage prevents protrusion; unilateral damage causes the jaw to deviate toward the side of the lesion on opening.
- Cummings Otolaryngology, Ch. 86
Q9. What is the blood supply to all four primary muscles of mastication?
Show Answer
Branches of the maxillary artery (a terminal branch of the external carotid artery).
- K.J. Lee's Essential Otolaryngology
Q10. During normal jaw opening, what happens at the temporomandibular joint beyond simple rotation - and which muscle drives this movement?
Show Answer
During opening, the mandibular head translates (protrudes) forward onto the articular tubercle in addition to rotating. This forward translation is driven primarily by the lateral pterygoid (inferior head), assisted by gravity and the digastric/mylohyoid muscles.
- Gray's Anatomy for Students, p. 1116
Score Guide: 9-10 correct = Excellent | 7-8 = Good | 5-6 = Review pterygoids and functions | <5 = Re-read the chapter

I have rich textbook content from Scott-Brown's Otorhinolaryngology, Cummings Otolaryngology, Gray's Anatomy, and Rosen's Emergency Medicine. Here is the quiz:

Temporomandibular Joint (TMJ) - 10 Question Quiz

Q1. What type of joint is the TMJ, and which two bony structures articulate to form it?
Show Answer
The TMJ is a synovial joint. It is formed by the mandibular (glenoid) fossa of the temporal bone articulating with the mandibular condyle.
- Scott-Brown's Otorhinolaryngology Head & Neck Surgery, Ch. 41
Q2. The TMJ has four unusual features that distinguish it from most other synovial joints. Name them.
Show Answer
  1. The joint space is divided into upper and lower cavities by an intra-articular disc.
  2. Articular surfaces are covered by fibrous tissue (not hyaline cartilage), reflecting intramembranous development.
  3. A secondary condylar cartilage is present in the condyle head until adolescence.
  4. Movements of the joint are influenced by the teeth.
- Scott-Brown's Otorhinolaryngology Head & Neck Surgery, Ch. 41
Q3. The TMJ disc divides the joint into two compartments, each permitting a different type of movement. What movement occurs in each compartment?
Show Answer
  • Upper compartment - gliding (translatory) movement
  • Lower compartment - hinge (rotatory) movement
- Scott-Brown's Otorhinolaryngology Head & Neck Surgery, Ch. 41
Q4. Describe the structure of the retrodiscal tissue (bilaminar zone) and the functional significance of each lamina.
Show Answer
The retrodiscal tissue has a bilaminar structure:
  • Superior lamina - loose, highly vascular, contains elastin fibres; attaches to the squamotympanic fissure. Its elastic recoil may help the disc return to position on jaw closing.
  • Inferior lamina - relatively avascular, less extensible (few elastin fibres); attaches to the posterior margin of the condyle.
The retrodiscal tissue volume increases 4-5x via venous engorgement as the jaw opens.
- Scott-Brown's Otorhinolaryngology Head & Neck Surgery, Ch. 41
Q5. Which muscle inserts onto the pterygoid fovea of the mandibular condyle, and what is the pterygoid fovea?
Show Answer
The lateral pterygoid muscle inserts here. The pterygoid fovea is a small depression on the anterior surface of the neck of the condyle, which also receives fibres attaching to the articular disc and TMJ capsule.
- Gray's Anatomy for Students, Table 8.11; Scott-Brown's, Ch. 41
Q6. Name the three ligaments associated with the TMJ. Which one is the principal ligament that limits mandibular movement?
Show Answer
The three ligaments are:
  1. Lateral (temporomandibular) ligament - the principal ligament; limits posterior displacement and rotation of the condyle
  2. Sphenomandibular ligament - accessory; from spine of sphenoid to lingula of mandible
  3. Stylomandibular ligament - accessory; from styloid process to angle/posterior border of mandible
- Gray's Anatomy for Students, Fig. 8.142
Q7. A patient presents unable to close their mouth after a wide yawn, with jaw protruding and deviation away from one side, drooling, and garbled speech. What is the diagnosis, and toward which side does the jaw deviate?
Show Answer
This is anterior dislocation of the TMJ. In unilateral dislocation, the jaw deviates away from the affected joint (toward the unaffected side). Bilateral dislocation causes symmetric protrusion without lateral deviation.
- Rosen's Emergency Medicine, Ch. on Facial Trauma
Q8. Describe the technique for manual reduction of a dislocated TMJ. What precaution must be taken regarding finger placement?
Show Answer
The patient is seated upright. The operator stands in front. Thumbs or index fingers are placed in the buccal sulcus (not on the crowns of the teeth) on either side. The angle of the jaw is pressed downward while the chin is rotated upward and backward. Adequate analgesia and sedation are required. If fingers must rest near tooth crowns, they should be wrapped in gauze - when reduction occurs, masticatory muscle spasm snaps the jaw shut forcefully.
- Rosen's Emergency Medicine, Ch. on Facial Trauma
Q9. What are the absolute indications for TMJ surgery? What imaging modality is most appropriate for evaluating the disc and soft tissue structures of the TMJ?
Show Answer
Absolute indications: treatment of neoplasms, growth abnormalities, and ankylosis of the joint.
For soft tissue and disc evaluation, MRI is the modality of choice (CT is preferred for bony fractures). Surgery is otherwise considered only when pain/dysfunction is refractory to non-surgical therapy (NSAIDs, physical therapy, occlusal splints, counselling) and imaging confirms pathology.
- Cummings Otolaryngology, Ch. 92
Q10. What is TMJ arthrocentesis, what does the procedure involve, and what is its reported success rate?
Show Answer
Arthrocentesis is the simplest, least invasive TMJ surgical procedure. It is performed under IV sedation and local anaesthesia. Two 18-gauge needles are inserted into the superior joint space - one for irrigation inflow, one for outflow - using Ringer's lactate for lavage. Blocking the outflow port allows distension for lysis of adhesions. It achieves a 70-90% success rate in reducing TMJ pain and improving mandibular range of motion.
- Cummings Otolaryngology, Ch. 92

Dural Venous Sinuses - 15 Question Quiz

Q1. What are dural venous sinuses, and what is unique about their walls compared to peripheral veins?
Show Answer
Dural venous sinuses are venous channels of the dura mater that drain blood from the brain into the internal jugular veins. Their rigid walls are formed by the cranial periosteum and dura mater (not a muscular wall like peripheral veins). Their interior is lined with endothelium, and they are valveless.
- Color Atlas of Human Anatomy Vol. 2, p. 134
Q2. Name all the dural venous sinuses. (List at least 10.)
Show Answer
  1. Superior sagittal sinus
  2. Inferior sagittal sinus
  3. Straight sinus
  4. Occipital sinus
  5. Confluence of sinuses (torcular Herophili)
  6. Transverse sinus (right and left)
  7. Sigmoid sinus (right and left)
  8. Cavernous sinus (right and left)
  9. Intercavernous sinus
  10. Sphenoparietal sinus (right and left)
  11. Superior petrosal sinus (right and left)
  12. Inferior petrosal sinus (right and left)
  13. Basilar plexus
  14. Marginal sinus
- Gray's Anatomy for Students, Table 8.3
Q3. Where is the superior sagittal sinus located, and what does it receive?
Show Answer
It runs along the superior border of the falx cerebri, ending at the confluence of sinuses. It receives superior cerebral veins, diploic veins, emissary veins, and cerebrospinal fluid (via arachnoid granulations).
- Gray's Anatomy for Students, Table 8.3
Q4. The straight sinus lies at the junction of two dural folds. Name them, and list what it receives.
Show Answer
The straight sinus lies at the junction of the falx cerebri and the tentorium cerebelli. It receives the inferior sagittal sinus, the great cerebral vein (of Galen), posterior cerebral veins, superior cerebellar veins, and veins from the falx cerebri.
- Gray's Anatomy for Students, Table 8.3
Q5. What is the confluence of sinuses (torcular Herophili)? Where is it located, and which sinuses meet there?
Show Answer
The confluence of sinuses is a dilated venous space at the internal occipital protuberance. It receives the superior sagittal, straight, and occipital sinuses, and gives rise to the right and left transverse sinuses.
- Gray's Anatomy for Students, Table 8.3; Color Atlas of Human Anatomy, p. 134
Q6. Describe the course of the sigmoid sinus from origin to termination.
Show Answer
The sigmoid sinus is a continuation of the transverse sinus. It travels in an S-shaped course along the posterior inferior border of the petrous part of the temporal bone (grooving the parietal, temporal, and occipital bones) and terminates at the jugular foramen, where it becomes the internal jugular vein.
- Color Atlas of Human Anatomy Vol. 2, p. 134
Q7. The cavernous sinus has a very important anatomical relationship with several structures that pass through or within its walls. List all the structures and specify which pass through the sinus itself vs. in its lateral wall.
Show Answer
Passing through the sinus:
  • Internal carotid artery
  • Abducent nerve (CN VI)
In the lateral wall (medial to lateral order):
  • Oculomotor nerve (CN III)
  • Trochlear nerve (CN IV)
  • Ophthalmic branch of trigeminal (V1)
  • Maxillary branch of trigeminal (V2)
- Color Atlas of Human Anatomy, p. 134; Harrison's Principles of Internal Medicine 22E
Q8. Name four tributaries that drain into the cavernous sinus.
Show Answer
  1. Superior and inferior ophthalmic veins (connecting to the facial/angular vein)
  2. Sphenoparietal sinus
  3. Superficial cerebral veins
  4. Emissary veins from the pterygoid plexus
  5. Intercavernous sinuses (connecting the two cavernous sinuses across the sella turcica)
- Gray's Anatomy for Students, Table 8.3; Color Atlas of Human Anatomy, p. 134
Q9. What is the clinical significance of the connection between the cavernous sinus and the facial vein? Give a clinical example.
Show Answer
The cavernous sinus communicates with the facial/angular vein via the superior ophthalmic vein. This creates a route for infection to spread from the "danger triangle of the face" (upper lip, nose) to the cavernous sinus - a valveless pathway. A furuncle or infected pimple in this region can lead to septic cavernous sinus thrombosis, a life-threatening condition.
- Color Atlas of Human Anatomy, p. 134
Q10. A patient develops fever, headache, proptosis, chemosis, and painful ophthalmoplegia with ptosis. What is the diagnosis, and which cranial nerves are involved?
Show Answer
Septic cavernous sinus thrombosis. Cranial nerves affected are:
  • CN III (oculomotor) - ptosis, ophthalmoplegia
  • CN IV (trochlear) - loss of superior oblique function
  • CN VI (abducens) - lateral gaze palsy (often the earliest nerve affected due to its position inside the sinus)
  • CN V1 and V2 (ophthalmic and maxillary) - hyperesthesia, decreased corneal reflex
Signs also include dilated tortuous retinal veins and papilledema from raised venous pressure.
- Harrison's Principles of Internal Medicine 22E
Q11. Thrombosis of the transverse sinus presents with a characteristic symptom triad. What is it, and what associated condition can cause it?
Show Answer
Transverse sinus thrombosis classically presents with headache, earache (otalgia), and sixth nerve (CN VI) palsy, with retroorbital or facial pain - known as Gradenigo's syndrome. It is strongly associated with otitis media (infection spreading from the mastoid/middle ear to the adjacent sigmoid-transverse sinus system).
- Harrison's Principles of Internal Medicine 22E
Q12. What is the marginal sinus, and what does it connect?
Show Answer
The marginal sinus encircles the foramen magnum and connects the dural venous sinuses with the vertebral venous plexuses. It links the occipital/confluence system above with the extracranial epidural venous network of the spine below.
- Color Atlas of Human Anatomy Vol. 2, p. 134
Q13. What is the preferred imaging modality for diagnosing dural venous sinus thrombosis, and what is the key diagnostic finding on MRI?
Show Answer
The diagnosis is suggested by an absent flow void within the affected sinus on standard MRI. Confirmation is by contrast-enhanced MR venography (MRV), CT venography, or the venous phase of cerebral angiography. MRV is the modality of choice.
- Harrison's Principles of Internal Medicine 22E
Q14. What is the first-line treatment for aseptic dural venous sinus thrombosis, and what is the concern with using it when hemorrhagic infarction is present?
Show Answer
First-line treatment is anticoagulation with unfractionated or low-molecular-weight heparin, followed by warfarin or a newer anticoagulant. The concern is that small intracerebral hemorrhage from septic thrombophlebitis is NOT an absolute contraindication to heparin - anticoagulation is still recommended when there is progressive neurological deterioration despite antibiotics. Mortality remains high (10-20% have large hemorrhagic venous infarctions).
- Harrison's 22E; Adams & Victor's Principles of Neurology 12th Ed.
Q15. Deep cerebral vein thrombosis (occlusion of the vein of Galen and internal cerebral veins) produces a distinctive clinical picture. Describe it and name the structure most affected on imaging.
Show Answer
Deep cerebral vein thrombosis produces bithalamic infarction, manifesting as inattention, spatial neglect, amnesia, akinetic mutism, and apathy. Coma and pupillary changes may occur in severe cases. On MRI, a large bilobular region of signal change encompassing both thalami is the hallmark finding - much of which may represent reversible edema. Confirmation requires MR venography.
- Adams & Victor's Principles of Neurology, 12th Ed.
