Detailed explanation-1: -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. It is classified as the eleventh of twelve pairs of cranial nerves because part of it was formerly believed to originate in the brain.
Detailed explanation-2: -The accessory nerve is a cranial nerve that controls the movement of certain neck muscles. It is coiled in appearance. It is divided into spinal and cranial divisions, but its cranial part is often disregarded.
Detailed explanation-3: -The cranial accessory nerve has a similar function to the vagus nerve. It carries motor innervation to the pharyngeal constrictors, larynx, and muscles of the soft palate (except tensor veli palatini).
