Explanation: Postganglionic parasympathetic fibres from the otic ganglion travel with the auriculotemporal nerve to reach the parotid gland.

• A. Lingual nerve
• B. Auriculotemporal nerve
• C. Chorda tympani

Explanation: Before entering the mandibular foramen, the inferior alveolar nerve descends between the pterygoid muscles, lying lateral to the medial…

• A. Frontal
• B. Lacrimal
• C. Nasociliary
• D. Medial ethmoid

Explanation: The three direct divisions of the ophthalmic nerve are the frontal, lacrimal and nasociliary nerves.

• A. Lingual nerve
• B. Inferior alveolar nerve
• C. Deep temporal nerve

Explanation: The posterior division of V3 gives the auriculotemporal, lingual and inferior alveolar nerves.

• A. Anterior belly of digastric, mylohyoid , tensor tympani , tensor palati
• B. Posterior belly of digastric, mylohyoid
• C. Stapes, malleus, incus
• D. Anterior belly of digastric, stapes

Explanation: V3 supplies the muscles derived from the first pharyngeal arch, including the anterior digastric, mylohyoid, tensor tympani and tensor…

• A. Is in relation to maxillary nerve
• B. Receives preganglionic parasympathetic fibers, through the greater superficial petrosal nerve
• C. Sends postganglionic parasympathetic fibers to auriculotemporal nerve
• D. Is related to the tensor tympani

Explanation: The otic ganglion receives preganglionic fibres through the lesser petrosal nerve, not the greater petrosal nerve.

• A. Masseteric and auriculotemporal nerve
• B. Superficial temporal nerve
• C. Facial nerve peripheral branch
• D. Posterior auricular nerve

Explanation: The main sensory supply of the temporomandibular joint comes from the auriculotemporal and masseteric nerves, both branches of V3.

• A. Medial pterygoid
• B. Masseter
• C. Buccinator
• D. Anterior belly of digastric

Explanation: The medial pterygoid, masseter and anterior digastric receive motor fibres from the mandibular nerve.

• A. Lingual nerve
• B. Inferior alveolar nerve
• C. Mylohyoid nerve
• D. None of the above

Explanation: The lingual nerve is closely related to the posterior part of the mylohyoid ridge and then passes medially near the mandibular third molar…

• A. Buccal branch of the facial nerve
• B. Buccal branch of the mandibular nerve
• C. Mandibular branch of the facial nerve
• D. Mental nerve

Explanation: The mental nerve, the terminal branch of the inferior alveolar nerve, emerges through the mental foramen and supplies sensation to the…

• A. III
• B. IV
• C. V
• D. VII

Explanation: The levator palpebrae superioris raises the upper eyelid and is supplied by the oculomotor nerve, cranial nerve III.

• A. Muscles which close the eyelid are supplied by the facial nerve
• B. Muscles which open the eyelid are supplied by the branch of trigeminal nerve
• C. Sensory supply is by the 5th cranial nerve
• D. Blood supply is by the lacrimal and ophthalmic arteries

Explanation: The upper eyelid is opened mainly by levator palpebrae superioris through cranial nerve III, with sympathetic supply to the superior…

• A. Straight sinus
• B. Cavernous sinus
• C. Sigmoid sinus
• D. Ethmoidal sinus

Explanation: The transverse sinus runs posterolaterally from the confluence of sinuses and becomes the sigmoid sinus at the transverse-sigmoid…

• A. Buccal artery
• B. Mental artery
• C. Posterior auricular artery
• D. Infra orbital artery

Explanation: Facial blood supply is reinforced by buccal, mental and infraorbital arteries, which anastomose extensively in the face.

• A. Middle meningeal artery
• B. Facial artery
• C. Temporal artery
• D. Anterior cerebral artery

Explanation: The middle meningeal artery runs deep to the pterion, where a fracture can tear it and produce an extradural, or epidural, hematoma.

• A. Intracavernous
• B. Intrapetrous
• C. Inracerebral
