Answer 1

Answer: (C)

Hypoglossal nerve

The hypoglossal nerve is the twelfth cranial nerve and innervates muscles of the tongue. The hypoglossal nerve arises from the hypoglossal nucleus of the caudal brain stem, emerging from the ventromedial medulla oblongata from a number of smaller rootlets in the preolivary sulcus, separating the olive and the pyramid.
