- 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

- 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: Branches of cervical plexus- A. Nerve, Artery and vein
- B. Artery , Nerve and vein
- C. Vein, Artery and Nerve
- D. Nerve, Artery
Explanation: From medial to lateral, the lingual artery is followed by the lingual nerve and then the lingual vein.
Correct answer: Artery , Nerve and vein48. The nerve that emerges from the two superficial heads of lateral pterygoid muscle is______________?
- A. Buccale nerve
- B. Massetric nerve
- C. Nerve to pterygoid muscle
- D. Inferior alveolar nerve
Explanation: The buccal nerve passes between the superficial and deep heads of the lateral pterygoid before supplying sensation to the cheek.
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…
Correct answer: Opthalmic- A. Superior ganglion
- B. Middle ganglion
- C. Stellate ganglion
- D. Second thoracic ganglion
Explanation: The superior cervical sympathetic ganglion is the largest ganglion of the cervical sympathetic chain, extending roughly from the level of…
Correct answer: Superior ganglion51. All of the following are features of an injury to the cerival sympathetic trunk EXCEPT_____________?
- A. Anhydrosis
- B. Enophthalmos
- C. Mydriasis
- D. Ptosis
Explanation: Damage to the cervical sympathetic trunk produces Horner syndrome, including anhidrosis, apparent enophthalmos and ptosis, with miosis…
Correct answer: Mydriasis- A. Genioglossus
- B. Palatoglossus
- C. Superior longitudinal muscle
- D. Inferior longitudinal muscle
Explanation: The hypoglossal nerve supplies all intrinsic and most extrinsic tongue muscles, but palatoglossus is supplied by the vagus nerve through…
Correct answer: Palatoglossus- A. Sternomastoid
- B. Trapezius
- C. Splenius capitis
- D. Soft palate
Explanation: The cranial root of the accessory nerve joins the vagus and contributes motor fibres to the muscles of the soft palate, pharynx and…
Correct answer: Soft palate- A. Recurrent laryngeal nerve
- B. Internal laryngeal nerve
- C. External laryngeal nerve
- D. Hypoglossal nerve
Explanation: The external laryngeal nerve, a branch of the superior laryngeal nerve, supplies the cricothyroid muscle and helps tense the vocal cords.
Correct answer: External laryngeal nerve- A. The levator velti palatine ( levator palatini)
- B. The psterior belly of digastric
- C. Mylohyoid
- D. The tensor veli palatine ( tensor palatini)
