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
