  {Spinal  accessory  nerves},  the  eleventh  pair  of  cranial 
  nerves  in  the  higher  vertebrates.  They  originate  from  the

  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.
