The superficial fibular nerve (superficial peroneal nerve) innervates the Peronei longus and brevis and the skin over the greater part of the dorsum of the foot (with the exception of the first web space, which is innervated by the deep peroneal nerve).
It passes forward between the Peronæi and the Extensor digitorum longus, pierces the deep fascia at the lower third of the leg, and divides into a medial and an intermediate dorsal cutaneous nerve.
In its course between the muscles, the nerve gives off muscular branches to peroneus longus and peroneus brevis, and cutaneous filaments to the integument of the lower part of the leg.
