Runs down the neck past important blood vessels ( carotid artery and jugular vein). It is purely motor nerve. What does the hypoglossal nerve pass through? It is a nerve with a solely motor function. The nerve arises from the hypoglossal nucleus in the medulla as a number of small rootlets, passes through the hypoglossal canal and down through the neck, and eventually passes up again over the tongue muscles it supplies into the tongue. The hypoglossal nerve passes through the genioglossus muscle and into the body of the tongue, where it breaks up into its terminal branches and innervates both the intrinsic and the extrinsic muscles of the tongue. It innervates all the extrinsic and intrinsic muscles of the tongue, except for the palatoglossus Structure. The hypoglossal nerve is purely motor nerve, which innervates extrinsic tongue muscles and geniohyoid muscle.
