    Sjjinal Nerves (Fig. 37).—There are thirty-one nerves given off from each side of the spinal cord, each nerve forming with its fellow on the opposite side a pair similar to the arrangement of the cranial nerves. They also re- semble those nerves in appearance. Each pair of nerves are composed of fibers arising from the anterior and poste- rior columns of the cord, and consequently contain motor and sensory fibers. At a short distance from the spinal cord the nerves divide into anterior and posterior branch- es, the anterior branches supply- ing the trunk and extremities, dia- phragm, and cer- tain organs. The posterior or small- er branches sup- ply principally the muscles and skin of the back. The brain and spinal cord are each protected by a closed sac, sur- rounding them, after the manner of the pericardium which envelops the heart, and the pleura covering the lungs. The portion of the nervous system just described presides over the func- tions of animal life—the intellect, general sensation, the special senses, and motion. Sympathetic System.—Organic life, or that which relates to secretion and excretion, the proper distribution -The sympathetic or ganglionic nervous system.
