It must not be suspected that the portions of the pos- terior columns named contain all the fibers of a posterior root. Many fibers, immediately after entering the cord, gain the gray matter, while others bend in their course, to pass through the posterior columns. Therefore there lie in the upper sections of the cord relatively few of those fibers in the posterior columns which entered lower down. Ex
. The anatomy of the central nervous system of man and of vertebrates in general. Neuroanatomy; Central Nervous System. PEEIPHEEAL-NEEVE KOOTS, SPINAL GANGLIA, SPINAL COED. 349 upper extremities. It must not be suspected that the portions of the pos- terior columns named contain all the fibers of a posterior root. Many fibers, immediately after entering the cord, gain the gray matter, while others bend in their course, to pass through the posterior columns. Therefore there lie in the upper sections of the cord relatively few of those fibers in the posterior columns which entered lower down. Experimentally this has been proved by following up the cord from a divided dorsal root, when the degenerating portion of the cord grows smaller and smaller as ©ne ascends. At the same time the degenerated field approaches more nearl}^ the median line. In the highest part of the cord the funiculus cuneatus contains fibers which do not come direct from the dorsal roots. Their origin is uncertain. A part of the posterior-root fibers extends to the vicinity of Clarke's column of cells and there arborizes (Fig. 227). From this column of cells.
