lateral plantar nerve

(redirected from nervus plantaris lateralis)

lat·er·al plan·tar nerve

[TA]
one of two terminal branches of the tibial nerve; it courses along the lateral side of the sole, dividing into superficial and deep branches; it supplies the skin of the lateral aspect of the sole and the lateral one-and-a-half toes; it innervates the intrinsic muscles of the plantar part of the foot with the exception of the abductor hallucis and the flexor digitorum brevis; its distribution in the foot is similar to that of the ulnar nerve in the hand.
Synonym(s): nervus plantaris lateralis [TA]

lateral plantar nerve

one of the two terminal branches of the tibial nerve that innervates all but three intrinsic muscles in the sole of the foot and a strip of skin on the lateral side of the anterior two thirds of the sole and the adjacent plantar surfaces of the fifth toe and lateral half of the fourth.

lateral plantar nerve

terminal division of sciatic nerve, subserving plantar sensation; its first branch forms Baxter's nerve; see Table 1; its deep branch innervates adductor hallucis, lateral three lumbricals, medial two plantar interossei and medial three dorsal interossei
