Detailed explanation-1: -The muscles innervated directly by the XI nerve are the trapezius and the sternocleidomastoid, in addition to the laryngeal musculature (in collaboration with the vagus nerve), such as the palatal, pharyngeal, laryngeal muscles.
Detailed explanation-2: -The accessory nerve, also known as the eleventh cranial nerve, cranial nerve XI, or simply CN XI, is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles.
Detailed explanation-3: -Optic nerve (CN II) Cranial nerve 2 is a special somatic afferent nerve which innervates the retina of the eye and brings visual information to the brain. Neural fibers originate from the photoreceptors of the retina. They converge at the optic disc, forming the optic nerve.
