Ask a question


The peroneal nerve is one of the two end portions of the sciatic nerve. In simpler terms, the peroneal nerve is located in the leg. Starting above the popliteal fossa, the nerve branches into two terminal branches - the deep peroneal and superficial peroneal nerves - as well as four collateral nerves that are the articular knee muscle, cutaneous peroneal, sural peroneal, and upper anterior tibial muscle nerves.
