Detailed explanation-1: -The hypoglossal nerve enables tongue movement. It controls the hyoglossus, intrinsic, genioglossus and styloglossus muscles. These muscles help you speak, swallow and move substances around in your mouth.
Detailed explanation-2: -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.
Detailed explanation-3: -The glossopharyngeal nerve is the ninth set of 12 cranial nerves (CN IX). It provides motor, parasympathetic and sensory information to your mouth and throat. Among its many functions, the nerve helps raise part of your throat, enabling swallowing.
Detailed explanation-4: -The hypoglossal nerve (CN XII) provides motor innervation to all of the intrinsic and extrinsic muscles of the tongue except for the palatoglossus muscle, which is innervated by the vagus nerve (CN X).
