The Accessory Nerve: Anatomy, Function, and Treatment

The accessory nerve provides motor function (movement) to two muscles essential to neck and shoulder movement, the sternocleidomastoid (SCM) and the trapezius, as well as to the larynx (voice box) and other structures in the throat.It’s the 11th of the …

The Accessory Nerve
The accessory nerve (Figs. 792, 793, 794) consists of two parts: a cranial and a spinal. The Cranial Part (ramus internus; accessory portion) is the smaller of the two.Its fibers arise from the cells of the nucleus ambiguus and emerge as four or five delicate rootlets from the side of the medulla oblongata, below the roots of the vagus.

Spinal Accessory Nerve Entrapment Syndrome

Spinal accessory nerve can be secondary to neuromas at the base of the skull, fractures of the occipital condyle, or result of surgical complications. However it is very commonly with trauma to the neck, and in some cases can be the result after whiplash injuries.

Cranial Nerve Anatomy and Function

Pathway The visual stimulus is relayed contralaterally in CN II to the occipital cortex via the thalamus. The response to this stimulation is initiated via the motor cortex which ultimately stimulates the ipsilateral facial nerve (CN VII) to cause eyelid closure.

classification Among investigators there is disagreement regarding the terminology used to describe the type of information carried by the accessory nerve. As the trapezius and sternocleidomastoid muscles are derived from the pharyngeal arches, some investigators believe the spinal accessory nerve that innervates them must carry specific special visceral efferent (SVE) information.
