      nerves in the higher vertebrates. they originate from the

      they emerge in company with the pneumogastrics.

      vertebrae which forms the axis of the vertebrate skeleton;

   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.
