 FIBERS OF THE SPINAL CORD. Lateral aspect of the cord. 



a, Anterior median fissure; ac, cells of the anterior horn; an, anterior root 

 of spinal nerve ; c, axis-cylinder process ; co, collateral fibers ; e, fibers 

 connecting higher brain centers with cerebellum ; fi, sensory fibers 

 of fillet to the brain; g, gn, go, ganglion of posterior root; gr, gray 

 matter ; ir, fibers of the posterior sensory tract ; /, fibers to cerebellum ; 

 777, cells in the anterior horn or column of gray matter ; n, spinal nerves ; 

 o, cells in the posterior horn or column of gray matter; nc, nucleus 

 gracilis and nucleus cuneatus; nr, nucleus ruber; r, a fiber of pos- 

 terior root ; rb, ganglion cells of medulla ; s, tract of fillet to the brain ; 

 sp, fibers of superior peduncle of the cerebellum; t f , fiber of crossed 

 pyramidal tract ; is, point of decussation ; v, division of fiber x into 

 its cephalic and caudal extensions ; w, a collateral of the longitudinal
