Anatomy Of Sciatic Nerve
The sciatic nerve , also called the ischiadic nerve , is a large nerve in humans and other vertebrate animals which is the largest branch of the sacral plexus and runs alongside the hip joint and down the lower limb . It is the longest and widest single nerve in the human body , going from the top of the leg to the foot on the posterior aspect. The sciatic nerve has no cutaneous branches for the thigh. This nerve provides the connection to the nervous system for the skin of the lateral leg and the whole foot, the muscles of the back of the thigh, and those of the leg and foot. It is derived from spinal nerves L4 to S3 . It contains fibers from both the anterior and posterior divisions of the lumbosacral plexus.
