Introduction:

The spinal nerves are important because the spinal cord sends and receive signals from the body through the spinal nerves. The spinal nerve is composed of large number of nerve fibers or axons and resembles a cord-like appearance. The nervous tissue of the spinal cord is composed of organized cells that involve the body movements and send the signals to different parts of the body. The spinal cord tracts are stimulatory nerve pathways that pass the information through action potentials.
