Questions 1-30: Head and Neck Anatomy
1. The parotid gland is innervated by which cranial nerve for secretomotor function?
A) Cranial Nerve V (Trigeminal)
B) Cranial Nerve VII (Facial)
C) Cranial Nerve IX (Glossopharyngeal)
D) Cranial Nerve X (Vagus)
Answer: C (The parotid gland receives parasympathetic secretomotor innervation from the
glossopharyngeal nerve (CN IX) via the otic ganglion. The facial nerve (CN VII) innervates the
submandibular and sublingual glands.)
2. Which of the following foramina transmits the maxillary division of the trigeminal nerve
(V2)?
1
SUCCESS!
,Page 2 of 134
A) Foramen rotundum
B) Foramen ovale
C) Foramen spinosum
D) Superior orbital fissure
Answer: A (The foramen rotundum transmits the maxillary nerve (V2). The foramen ovale
transmits the mandibular nerve (V3). The foramen spinosum transmits the middle meningeal
artery.)
3. The infraorbital nerve is a branch of which nerve?
A) Ophthalmic nerve (V1)
B) Maxillary nerve (V2)
C) Mandibular nerve (V3)
D) Facial nerve (VII)
Answer: B (The infraorbital nerve is a terminal branch of the maxillary nerve (V2), exiting
through the infraorbital foramen to provide sensation to the lower eyelid, nose, and upper lip.)
4. Which muscle is primarily responsible for protrusion of the mandible?
2
SUCCESS!
,Page 3 of 134
A) Masseter
B) Temporalis
C) Medial pterygoid
D) Lateral pterygoid
Answer: D (The lateral pterygoid muscle protrudes the mandible by pulling the condyle and
articular disc forward. The masseter and medial pterygoid elevate the mandible.)
5. The pterygomandibular raphe serves as an attachment for which muscles?
A) Buccinator and superior pharyngeal constrictor
B) Masseter and temporalis
C) Lateral and medial pterygoid
D) Digastric and mylohyoid
Answer: A (The pterygomandibular raphe provides attachment for the buccinator muscle
anteriorly and the superior pharyngeal constrictor posteriorly.)
6. Which of the following structures passes through the parotid gland?
A) Facial nerve (CN VII)
3
SUCCESS!
, Page 4 of 134
B) Hypoglossal nerve (CN XII)
C) Glossopharyngeal nerve (CN IX)
D) Vagus nerve (CN X)
Answer: A (The facial nerve (CN VII) passes through the parotid gland, dividing into its five
terminal branches. The retromandibular vein and external carotid artery also pass through the
gland.)
7. The mandibular division of the trigeminal nerve (V3) exits the skull through which
foramen?
A) Foramen rotundum
B) Foramen ovale
C) Foramen spinosum
D) Jugular foramen
Answer: B (The mandibular nerve (V3) exits through the foramen ovale. The foramen rotundum
transmits V2, and the foramen spinosum transmits the middle meningeal artery.)
8. Which of the following is a branch of the maxillary artery that supplies the teeth and
supporting structures of the maxilla?
4
