- 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.
Correct answer: Sends postganglionic parasympathetic fibers to auriculotemporal 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.
Correct answer: Masseteric and auriculotemporal nerve- 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.
Correct answer: Buccinator144. The structure that is closely related to the posterior end of the mylohyoid ridge is_______________?
- 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…
Correct answer: Lingual nerve- 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…
Correct answer: Mental nerve- 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.
Correct answer: 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…
Correct answer: Muscles which open the eyelid are supplied by the branch of trigeminal nerve- 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…
Correct answer: Sigmoid sinus- 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.
Correct answer: Posterior auricular artery- 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.
Correct answer: Middle meningeal artery- A. Intracavernous
- B. Intrapetrous
- C. Inracerebral
- D. Extra cranial
Explanation: The ophthalmic artery arises from the internal carotid after it has passed through the cavernous sinus, from its intracranial or cerebral…
Correct answer: Inracerebral- A. Main source of oxygenated blood to palatine tonsil
- B. Is a branch of internal carotid artery
- C. Supplies branches to both upper and lower lips
- D. Conveys post ganglionic sympathetic nerve fibres to the submandibular gland
Explanation: The facial artery is a branch of the external carotid artery, not the internal carotid artery.
Correct answer: Is a branch of internal carotid artery- A. Inferior petrosal sinus
- B. Pterygoid venous plexus
- C. Veins in orbit
- D. Sigmoid and straight sinus
Explanation: The cavernous sinus communicates with the inferior petrosal sinus, orbital veins and the pterygoid plexus through emissary veins.
Correct answer: Sigmoid and straight sinus- A. Middle cerebral artery
- B. External carotid artery
- C. Internal carotid artery
- D. Ophthamic artery
Explanation: The posterior communicating artery arises from the internal carotid artery and runs posteriorly to join the posterior cerebral artery.
Correct answer: Internal carotid artery- A. Above the line joining tragus to the nasal fold
- B. Area drained by angular facial vein
- C. Spheno - ethmoidal recess
- D. All of the above
Explanation: The dangerous area of the face is clinically important because the facial vein communicates through the angular and ophthalmic veins with…
Correct answer: Area drained by angular facial vein- A. Intra cavernous
- B. Intra petrous
- C. Intra cerebral
- D. Extra cranial
Explanation: The ophthalmic artery arises from the intracranial, or cerebral/supraclinoid, part of the internal carotid artery after it emerges from…
Correct answer: Intra cerebral- A. Ascending pharyngeal
- B. Middle meningeal
- C. Artery of pterygoid canal
- D. All of the above
Explanation: The auditory tube receives arterial branches from the ascending pharyngeal artery, middle meningeal artery and artery of the pterygoid…
Correct answer: All of the above- A. Stage - I
- B. Stage - II
- C. Stage - III
- D. Stage - IV
Explanation: The first stage of swallowing transfers the bolus from the mouth into the oropharynx and is under voluntary control.
Correct answer: Stage - I- A. Cavernous sinus
- B. Superior petrosal
- C. Transverse sinus
- D. All of the above
Explanation: The cavernous, superior petrosal and transverse sinuses are all paired dural venous sinuses, with right and left members.
