- C. Occulomotor nerve
- D. Glossopharyngeal nerveExplore Anatomy Models
Explanation: General sensation from the nasal cavity is carried mainly by branches of the trigeminal nerve, especially the ophthalmic and maxillary…
Correct answer: Trigeminal nerve- A. Ascending pharyngeal
- B. Ascending palatine
- C. Middle meningeal artery
- D. Artery of pterygoid canal
Explanation: The pharyngotympanic tube receives branches from the ascending pharyngeal, middle meningeal and artery of the pterygoid canal.
Correct answer: Ascending palatine- A. Taste
- B. Lacrimation
- C. Saliva
- D. Sweating
Explanation: The geniculate ganglion contains sensory cell bodies for taste carried by the nervus intermedius, chiefly from the anterior two-thirds of…
Correct answer: Taste- A. Greater petrosal nerve
- B. Lesser petrosal nerve
- C. Sphenopalatine nerve
- D. Nasocilliary nerveExplore Anatomy Models
Explanation: Preganglionic parasympathetic fibres for lacrimation travel in the greater petrosal nerve to the pterygopalatine ganglion, then reach the…
Correct answer: Greater petrosal nerve- A. Cavernous branch
- B. Inferior hypophyseal
- C. Meningeal artery
- D. Ophthalmic artery
Explanation: The ophthalmic artery arises from the supraclinoid part of the internal carotid artery after it leaves the cavernous sinus.
Correct answer: Ophthalmic artery- A. Facial Nerve
- B. Chorda Tympani
- C. Mylohyoid Nerve
- D. Lingual Nerve
Explanation: Secretomotor fibres reach the submandibular gland through the facial nerve, chorda tympani and lingual nerve, with relay in the…

- B. Superior orbital fissure
- C. Inferior orbital fissure
- D. Foramen ovale
Explanation: The oculomotor nerve enters the orbit through the superior orbital fissure, along with cranial nerves IV, V1 and VI.
Correct answer: Superior orbital fissure- A. Carries parasympathertic fibres
- B. Causes constriction of pupils
- C. Supplies inferior oblique muscle
- D. Passes through inferior orbital fissureMedical Literature & Resources
Explanation: The oculomotor nerve carries parasympathetic fibres, constricts the pupil through the sphincter pupillae, and supplies the inferior…
Correct answer: Passes through inferior orbital fissureMedical Literature & Resources- A. Stellate ganglion
- B. Spinal cord
- C. Parasympathertic ganglion
- D. Celiac ganglion
Explanation: Horner syndrome follows interruption of the cervical sympathetic pathway, commonly involving the stellate ganglion or lower cervical…
Correct answer: Stellate ganglion- A. Deep petrosal nerve
- B. Lesser superficial petrosal nerve
- C. External petrosal nerve
- D. Greater superficial petrosal nerve
Explanation: The greater petrosal nerve is a branch of the facial nerve carrying preganglionic parasympathetic fibres to the pterygopalatine ganglion.
Correct answer: Greater superficial petrosal nerve- A. Carries secretomotor fibrers to submandibular gland
- B. Joints lingual nerve in infratemporal fossa
- C. Is a branch of facial nerve
- D. Contains postganglionic parasympathetic fibers
Explanation: Chorda tympani is a branch of the facial nerve that joins the lingual nerve and carries preganglionic parasympathetic fibres to the…
Correct answer: Contains postganglionic parasympathetic fibers- A. Facial nerve
- B. Mandibular nerve
- C. Glosso Pharyngeal nerve
- D. Maxillary nerve
Explanation: The pterygopalatine ganglion is functionally associated with the facial nerve because it receives its preganglionic parasympathetic fibres…
Correct answer: Facial nerve- A. Branches of cervical plexus
- B. Vagus nerve
- C. Glossopharyngeal nerve
- D. Mandibular nerve
Explanation: Most infrahyoid muscles receive motor fibres through the ansa cervicalis, a loop formed by cervical spinal nerves C1 to C3.

Correct answer: Buccale nerve- A. Maxillary
- B. Mandibular
- C. Opthalmic
- D. Facial
Explanation: The tip of the nose receives sensory supply from the external nasal branch of the anterior ethmoidal nerve, a branch of ophthalmic…
