Medial plantar artery

The medial plantar artery (Latin: arteria plantaris medialis) is the smaller terminal branch of the posterior tibial artery, the other being the lateral plantar artery. The medial plantar artery with its branches supplies muscles of the big toe, as well as skin on the sole of the foot on the medial side.

The artery arises between the medial malleolus and the heel. At first, the medial plantar artery runs deep to the abductor hallucis muscle, later passing between it and the flexor digitorum brevis muscle, reaching the medial border of the hallux (big toe). On its course, the medial plantar artery gives off muscular branches and superficial digital branches.
