Introduction:

The spinal nerves are important because the spinal cord sends and receives signals from the body through the spinal nerves. The spinal nerve is composed of large number of nerve fibers or axons and resembles a cordlike appearance. The nerve plexuses are network or branch of intersecting nerves composed of nerve fibers (afferent and efferent). They are originated from the anterior ramus of spinal nerves and blood vessels.
