    2. Arises in upper spinal cord (not Medulla)
    3. Passes up through foramen magnum
      1. Runs along side vagal nerve (CN 10) briefly
      2. Descends through jugular foramen
    4. Runs backward near Jugular Vein
    5. Descends to upper sternocleidomastoid
    6. Proceeds to posterior triangle of neck to trapezius
  5. Exam
    1. Trapezius testing
      1. Patient raises Shoulders against resistance
    2. Sternocleidomastoid Testing
      1. Patient starts with head turned to the side
      2. Attempt to turn head back against resistance

Accessory nerve structure (C0000905)

Definition (NCI) The 11th cranial nerve, which sends motor impulses to the muscles of the upper thorax, back, shoulders, and pharynx.
Definition (NCI_CDISC) The eleventh cranial nerve.
Definition (MSH) The 11th cranial nerve which originates from NEURONS in the MEDULLA and in the CERVICAL SPINAL CORD. It has a cranial root, which joins the VAGUS NERVE (10th cranial) and sends motor fibers to the muscles of the LARYNX, and a spinal root, which sends motor fibers to the TRAPEZIUS and the sternocleidomastoid muscles.
