Medial plantar nerve

  • The medial plantar nerve (latin: nervus plantaris medialis) is one of the terminal branches of the tibial  nerve.

    The medial plantar nerve runs below the adductor hallucis muscle, then between it and the flexor digitorum brevis. In the end, the medial plantar nerve splits into three common digital plantar nerves and seven proper digital plantar nerves.

    The medial plantar nerve innervates the medial muscle group of the foot (except the adductor hallucis) and muscles of the middle group of the foot: the flexor digitorum brevis and the lumbricals. The terminal branches of the medial plantar nerve innervate the skin of the plantar side of the foot and the skin of first to third toe, and the medial surface of the fourth toe.
