     Spinal accessory nerves, the eleventh pair of cranial

     Spinal cord, the great nervous cord extending backward from
        the brain along the dorsal side of the spinal column of a
        vertebrate animal, and usually terminating in a threadlike
        appendage called the filum terminale; the spinal, or
        vertebral, marrow; the myelon. The nervous tissue consists
        of nerve fibers and nerve cells, the latter being confined
        to the so-called gray matter of the central portions of
        the cord, while the peripheral white matter is composed of
        nerve fibers only. The center of the cord is traversed by
        a slender canal connecting with the ventricles of the
        brain.
