Plantar Nerve - Lateral Plantar Nerve

Lateral Plantar Nerve

The lateral plantar nerve supplies quadratus plantae, flexor digiti minimi, adductor hallucis, the interossei, three lumbricals and abductor digiti minimi. Cutaneous innervation is to the lateral sole and lateral one and one half toes (like the ulnar nerve).

Famous quotes containing the word nerve:

    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. I’m surprised that a collegebred man like you hasn’t more sense. Don’t monkey with the buzzsaw.
    John Dos Passos (1896–1970)
