Sciatic Nerve

The sciatic nerve branches from the lumbar nerves. It is the largest and longest nerve in the body. The sciatic nerves descend into the buttocks and into the thighs, where they divide into the tibial and common peroneal nerves. The many branches of these nerves supply nerve impulses to and from the muscles and skin in the hip joints and thighs, the lower legs, feet and most of the skin below the knee.
