• A. Facial nerve
• B. Trigeminal nerve
• C. Mandibular nerve
• D. Glossopharyngeal nerve

Explanation: The posterior one-third of the tongue receives general sensory and taste fibers from the glossopharyngeal nerve.

• A. Glossopharyngeal nerve
• B. Stylohyoid ligament
• C. Lingual artery
• D. Hypoglossal nerve

Explanation: The hypoglossal nerve crosses the superficial or lateral surface of hyoglossus, not its medial surface.

• A. Separated from the epiglottis by gloss epiglottic folds
• B. Contains foramen caecum which is present on the dorsum of frenulum
• C. Contains 6 - 10 circumvallate papilla located posterior to sulcus terminals
• D. Embryologically derives from 1st branchial arch only

Explanation: The tongue is separated from the epiglottis by the median and two lateral glossoepiglottic folds, forming the valleculae between them.

• A. Hyoglossus
• B. Genioglossus
• C. Palatoglossus
• D. Styloglossus

Explanation: Genioglossus is called the safety muscle because its activity prevents the tongue from falling backward and obstructing the airway.

• A. Ascending palatine artery
• B. Ascending pharyngeal artery
• C. Lingual artery
• D. Facial artery

Explanation: The lingual artery, a branch of the external carotid artery, is the principal arterial supply of the tongue.

• A. XII cranial nerve
• B. IX cranial nerve
• C. X cranial nerve
• D. VII cranial nerve

Explanation: General sensation from the posterior one-third of the tongue is carried by the glossopharyngeal nerve, cranial nerve IX.

• A. VII
• B. V
• C. X
• D. IX

Explanation: The glossopharyngeal nerve, cranial nerve IX, carries both general sensation and taste from the posterior one-third of the tongue.

• A. Protrusion of tongue
• B. Posteriorly retracts the tongue
• C. Depression of tongue
• D. Elevation of tongue

Explanation: Styloglossus pulls the tongue backward and upward, so its principal actions are retraction and elevation.

• A. Submental nodes
• B. Supra clavicular node
• C. Sub mandibular nodes
• D. Superior deep cervical nodes

Explanation: Lymph from the tip of the tongue initially drains to the submental lymph nodes.

• A. Genioglossus
• B. Intrinsic muscles of tongue
• C. Styloglossus
• D. Palatoglossus

Explanation: Genioglossus projects the tongue forward because its muscle fibres arise from the mandible and insert into the tongue.

• A. Pectineus
• B. Rectus femoris
• C. Adductor magnus
• D. Biceps femoris

Explanation: Rectus femoris is a single quadriceps muscle supplied by the femoral nerve, whereas pectineus, adductor magnus and biceps femoris contain…

• A. Fourth
• B. Seventh
• C. Third
• D. Ninth

Explanation: Cranial nerves III, VII and IX carry preganglionic parasympathetic fibres to cranial autonomic ganglia.

• A. Purely motor
• B. Purely sensory
• C. Mixed nerve
• D. A peripheral nerve

Explanation: The hypoglossal nerve is a somatic motor cranial nerve supplying the tongue muscles, apart from palatoglossus.

• A. Three
• B. Four
• C. Five
• D. Six

Explanation: The trigeminal nerve has four main nuclei: motor, principal sensory, spinal trigeminal, and mesencephalic nuclei.

• A. III, IV, V, VII
• B. III, VII , VIII, IX
• C. III, VII, IX, X
• D. VII, IX, X, XI

Explanation: The cranial parasympathetic outflow travels with cranial nerves III, VII, IX and X.

• A. Nucleus tractus solitarius
• B. Nucleus ambigous
• C. Dorsal nucleus of vagus
• D. Long tract of trigeminal nerve

Explanation: Visceral sensory and taste fibres carried by cranial nerves VII, IX and X terminate mainly in the nucleus of the solitary tract.

• A. Motor nucleus
• B. Nucleus ambigous
• C. Nucleus of tractus solitarius
• D. Lacrimatory nucleus

Explanation: Special visceral afferent taste fibres of the facial nerve terminate centrally in the rostral nucleus of the solitary tract.

• A. Internal carotid artery
• B. Basilar artery
• C. Vertebral artery
• D. Labyrinthine artery

Explanation: The anterior spinal artery usually arises from the union of branches from both vertebral arteries near the level of the foramen magnum.

• A. Internal carotid
• B. External carotid
• C. Maxillary artery
• D. Facial artery

Explanation: The hypophysis receives superior and inferior hypophyseal arteries, which arise from the internal carotid artery and its branches.

• A. Purkinje
• B. Stellate
• C. Cajal
• D. Pyramidal

Explanation: Purkinje cells are the characteristic neurons of the cerebellar cortex, not the cerebral cortex.
