MICROANATOMY

Detailed explanation-1: -The hypoglossal nerve innervates the muscles of the tongue and is involved in tongue movements during speech, food manipulation, and swallowing.

Detailed explanation-2: -The hypoglossal nerve provides motor control of the extrinsic muscles of the tongue: genioglossus, hyoglossus, styloglossus, and the intrinsic muscles of the tongue. These represent all muscles of the tongue except the palatoglossus muscle. The hypoglossal nerve is of a general somatic efferent (GSE) type.

Detailed explanation-3: -The Hypoglossal nerve is the 12th cranial nerves that originate from the medulla obligate of the brain stem. It innervates all the extrinsic and intrinsic muscles of the tongue, except for the palatoglossus which is innervated by the vagus nerve. It is a nerve with a solely motor function.
