Detailed explanation-1: -The hypoglossal nerve, also known as the twelfth cranial nerve, cranial nerve XII, or simply CN XII, is a cranial nerve that innervates all the extrinsic and intrinsic muscles of the tongue except for the palatoglossus, which is innervated by the vagus nerve.
Detailed explanation-2: -Specifically, the spinal accessory nerve provides somatic motor innervation to the sternocleidomastoid and trapezius muscles, while the hypoglossal nerve provides somatic motor innervation to almost all the muscles of the tongue.
