Examination. The accessory nerve is tested by evaluating the function of the trapezius and sternocleidomastoid muscles. The trapezius muscle is tested by asking the patient to shrug their shoulders with and without resistance.
What is the main function of CN XI?
This nerve supplies the sternocleidomastoid and trapezius muscles, which have the following functions: Rotation of head away from the side of the contracting sternocleidomastoid muscle. Tilting of the head toward the contracting sternocleidomastoid muscle. Flexion of the neck by both sternocleidomastoid muscles.
How do you fix accessory nerves?

What happens if accessory nerve is damaged?
Injury to the spinal accessory nerve not only results in debilitating trapezius dysfunction, but can also result in chronic pain and debilitation with prolonged shoulder girdle dysfunction.
What does the accessory nerve control?
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.
What does the accessory nerve pass through?
The primary function of the accessory nerves (XI) is motor, to the muscles of the neck and upper back. These nerves originate in the motor nuclei of the spinal cord and medulla. They pass through the jugular foramina, between the occipital and temporal bones.

Does neuropathy affect taste?
Neuropathies can be described by the type of nerve affected. Some types mainly affect one or two types of nerves, but most affect all three: Motor nerves: These nerves control voluntary muscle movement. Sensory nerves: These nerves carry information from the senses — vision, hearing, smell, taste, touch — to the brain.
