The<unk>  peroneal nerve<unk> ; external popliteal nerve; peroneal nerve), about one-half the size of the tibial nerve, is derived from the dorsal branches of the fourth and fifth lumbar and the first and second sacral nerves.
It descends obliquely along the lateral side of the popliteal fossa to the head of the<unk>  close to the medial margin of the Biceps femoris muscle.
It lies between the tendon of the Biceps femoris and lateral head of the Gastrocnemius muscle, winds around the neck of the<unk>  between the Peronæus longus and the bone, and divides beneath the muscle into the superficial peroneal nerve (superficial<unk>  nerve) and deep peroneal nerve (deep<unk>  nerve).
