Main nerves of the lower limb - posterior (English)

The main nerve branch of the sacral plexus is the sciatic nerve. This is the longest nerve in your body supplying the entire skin of the leg, and muscles of the posterior thigh, leg and foot. At its terminal end, the sciatic nerve divides into the tibial nerve and common fibular nerve, which go on to supply the posterior and anterolateral compartments of the leg, respectively.
