Medial Plantar Nerve

Medial Plantar Nerve

Insertion

The medial plantar nerve enters the sole of the foot deep to the abductor hallucis muscle as well as move onward in the groove in between the abductor hallucis and flexor digitorum brevis, supplying sections to each of these muscles.

Branches

The medial plantar nerve gives a digital branch (proper plantar digital nerve) to the medial side of the big toe and after that splits into three nerves (common plantar digital nerves) on the plantar side of the flexor digitorum brevis, which continue forward to supply proper plantar digital branches to surrounding sides of toes I to IV. The nerve to the first lumbrical emerges via the first common plantar digital nerve.

Function

  • It stimulates skin on the majority of the anterior two-thirds of the sole as well as surrounding sides of the medial three as well as one-half toes that includes the great toe.
  • Along with this big region of plantar skin, the nerve also stimulates four intrinsic muscles the abductor hallucis, flexor digitorum brevis, flexor hallucis brevis, and also first lumbrical.
