- 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)
Explanation: Levator veli palatini is supplied through the pharyngeal plexus, mainly by vagal fibres.
Correct answer: The levator velti palatine ( levator palatini)- A. Symphathetic and lesser petrosal nerve
- B. Symphatetic and greater superficial petrosal nerve
- C. Chorda tympani
- D. Jacobson's nerve
Explanation: The nerve of the pterygoid canal is formed by the greater petrosal nerve carrying parasympathetic fibres and the deep petrosal nerve…
Correct answer: Symphatetic and greater superficial petrosal nerve- A. Lesser palatine nerve
- B. Greater palatine nerve
- C. Glossopharyngeal nerve
- D. Facial nerve
Explanation: The glossopharyngeal nerve provides the main sensory supply to the palatine tonsil and its mucosa.
Correct answer: Glossopharyngeal nerve- A. Greater petrosal nerve
- B. Lesser petrosal nerve
- C. Chorda tympani
- D. Auriculotemporal nerve
Explanation: Preganglionic parasympathetic fibres destined for the otic ganglion travel in the lesser petrosal nerve.
Correct answer: Lesser petrosal nerve- A. V nerve
- B. VII nerve
- C. IX nerve
- D. XII nerve
Explanation: The glossopharyngeal nerve is the afferent limb of the gag reflex, carrying sensation from the pharynx to the brainstem.
Correct answer: IX nerve- A. IX & VII cranial Nerves
- B. V & IX cranial Nerves
- C. V & X cranial Nerves
- D. IX & X cranial Nerves
Explanation: Parasympathetic secretomotor fibres to the salivary glands arise from cranial nerves VII and IX: facial nerve fibres supply submandibular…
Correct answer: IX & VII cranial Nerves- A. Facial nerve
- B. Vagus nerve
- C. Mylohyoid nerve
- D. Inferior alveolar nerve
Explanation: The posterior belly of the digastric is derived from the second pharyngeal arch and is therefore supplied by the facial nerve.
Correct answer: Facial nerve- A. Mixed nerve
- B. Sensory nerve
- C. Motor nerve
- D. Parasympathertic nerve
Explanation: The facial nerve is mixed because it carries branchial motor fibres, taste fibres from the anterior two-thirds of the tongue, and…
Correct answer: Mixed nerve- A. III cranial nerve
- B. V cranial nerve
- C. VII cranial nerve
- D. XI cranial nerve
Explanation: Stapedius is a muscle of facial expression derivatives and receives motor innervation from the facial nerve, cranial nerve VII.
Correct answer: VII cranial nerve- A. Mastication; trigeminal ( V cranial )
- B. mastication; facial ( VII cranial )
- C. Facial expression; trigeminal ( V cranial )
- D. Facial expression; facial ( VII cranial)
Explanation: Smiling and frowning are movements of facial expression, produced by muscles supplied by the facial nerve, cranial nerve VII.
Correct answer: Facial expression; facial ( VII cranial)- A. There is paralysis of facial muscles
- B. There is paralysis of muscles of mastication
- C. Paralysis of vocal cords
- D. A and B
Explanation: Damage to the right facial nerve causes weakness or paralysis of the ipsilateral muscles of facial expression, including difficulty…
Correct answer: There is paralysis of facial muscles- A. Digastric
- B. Stylohyoid
- C. Posterior auricular
- D. All of the above
Explanation: The facial nerve gives extracranial branches to the posterior auricular, stylohyoid, and posterior belly of digastric muscles before…
Correct answer: All of the above- A. Preganglionic sympathetic fibres
- B. Preganglionic parasympathetic fibres
- C. Postganglionic sympathetic fibres
- D. Postganglionic parasympathetic fibres
Explanation: Chorda tympani carries preganglionic parasympathetic fibres from the facial nerve to the submandibular ganglion, as well as taste fibres.
Correct answer: Preganglionic parasympathetic fibres- A. Facial nerve
- B. Mandibular nerve
- C. Maxillary nerve
- D. Auriculo temporal nerve
Explanation: Buccinator is a muscle of facial expression, so its motor supply comes from branches of the facial nerve.
Correct answer: Facial nerve- A. Stapedius
- B. Occipitofrontalis
- C. Anterior belly of digastric
- D. Buccinator
Explanation: The anterior belly of digastric is supplied by the mylohyoid nerve, a branch of the inferior alveolar nerve from V3.
Correct answer: Anterior belly of digastric- A. Mylohyoid nerve
- B. Branch of facial nerve
- C. Branch of cervical plexus
- D. Hypoglossal nerve
Explanation: The anterior belly of digastric is supplied by the mylohyoid nerve, which branches from the inferior alveolar nerve of the mandibular…
Correct answer: Mylohyoid nerve- A. Nasal mucosa
- B. Sublingual gland
- C. Ciliary ganglion
- D. B & C
Explanation: The pterygopalatine ganglion carries secretomotor fibres to the nasal mucosa and lacrimal gland, but it is not related to the sublingual…
