What are the two basic functional elements of a spinal nerve?

spinal nerve
Starting from the spinal cord trace a motor pathway to the adductor muscle of the thigh Include the spinal cord root spinal nerve nerve plexus and specific peripheral nerve involved in the pathway?
starting in the spinal cord, trace a motor pathway to the adductor muscles of the thigh. Include the spinal cord root, spinal nerve, nerve plexus, and specific peripheral nerve involved in the pathway
What is the spinal accessory nerve?
spinal accessory nerve (a nerve that helps control speech, swallowing, and certain movements of the head and neck)
What cranial nerve is used when rotating the head?
The spinal accessory nerve, or cranial nerve XI (eleven), is a purely motor nerve which innervates the trapezius and sternocleidomastoid muscles. The sternocleidomastoid muscles are used to turn the head. The Accessory nerve also provides somatic motor fibers to muscles of the soft palate, pharynx, and larynx (spinal and medullary fibers respectively.)
