Nerve: Superficial fibular nerve

Latin	n. peronæus superficialis or n. fibularis superficialis

From	Common peroneal nerve

The Superficial Fibular/Peroneal Nerve (musculocutaneous nerve of the leg) innervates the Peronei longus and brevis and the skin over the greater part of the dorsum of the foot.

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 the Peronæi longus and brevis, and cutaneous filaments to the integument of the lower part of the leg.

[edit] Medial dorsal cutaneous nerve

The medial dorsal cutaneous nerve (n. cutaneus dorsalis medialis; internal dorsal cutaneous branch) passes in front of the ankle-joint, and divides into two dorsal digital branches, one of which supplies the medial side of the great toe, the other, the adjacent side of the second and third toes.

It also supplies the integument of the medial side of the foot and ankle, and communicates with the saphenous nerve, and with the deep peroneal nerve.

[edit] Intermediate dorsal cutaneous nerve

The intermediate dorsal cutaneous nerve (n. cutaneus dorsalis intermedius; external dorsal cutaneous branch), the smaller, passes along the lateral part of the dorsum of the foot, and divides into dorsal digital branches, which supply the contiguous sides of the third and fourth, and of the fourth and fifth toes.

It also supplies the skin of the lateral side of the foot and ankle, and communicates with the sural nerve.

The branches of the superficial peroneal nerve supply the skin of the dorsal surfaces of all the toes excepting the lateral side of the little toe, and the adjoining sides of the great and second toes, the former being supplied by the lateral dorsal cutaneous nerve from the sural nerve, and the latter by the medial branch of the deep peroneal nerve.

Frequently some of the lateral branches of the superficial peroneal are absent, and their places are then taken by branches of the sural nerve.
