The sensory supply of the palate is through all of the following, EXCEPT:

A. Facial Nerve
B. Hypoglossal Nerve
C. Glossopharyngeal Nerve
D. Maxillary division of Trigeminal Nerve

Answer is B. Hypoglossal Nerve

General sensory nerves of the palate:

1. Middle and Posterior (lesser) Palatine nerves, which are branches of Maxillary nerve through the Pterygopalatine ganglion.
2. From the Glossopharyngeal nerve

Special sensory (Gustatory) nerves:  

• Carrying taste sensations from the oral surface. Are contained in the Lesser Palatine nerves. The fibres travel through the Greater Petrosal nerve to the geniculate ganglion of the Facial nerve and from there to the nucleus of the solitary tract.

Hypoglossal Nerve: It supplies motor fibres to all of the muscles of the tongue, except the palatoglossus muscle which is innervated by the vagus nerve (cranial nerve X) or, according to some classifications, by fibers from the glossopharyngeal nerve (cranial nerve IX) that "hitchhike" within the vagus. Hence, it is the only one which is purely motor.
