The intermediate dorsal cutaneous nerve (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.

Famous quotes containing the words nerve and/or intermediate:
“The American people is out to get the kaiser. We are bending every nerve and every energy towards that end; anybody who gets in the way of the great machine the energy and devotion of a hundred million patriots is building towards the stainless purpose of saving civilization from the Huns will be mashed like a fly. Im surprised that a collegebred man like you hasnt more sense. Dont monkey with the buzzsaw.”
—John Dos Passos (18961970)
“Complete courage and absolute cowardice are extremes that very few men fall into. The vast middle space contains all the intermediate kinds and degrees of courage; and these differ as much from one another as mens faces or their humors do.”
—François, Duc De La Rochefoucauld (16131680)
