The spinal accessory nerve is the eleventh cranial nerve, branching from the trigeminal nerve and the spinal cord, between the first and fourth cervical vertebrae. The spinal accessory nerve divides into a number of branches which innervate important structures. These include the cervical lymph glands, the larynx, the pharynx, and the sternomastoid and trapezius muscles.
