The plantar arteries. Deep view.
|Latin||arcus plantaris profundus|
|lateral plantar artery, deep plantar artery|
|plantar metatarsal arteries|
|plantar venous arch|
The plantar arch is a circulatory anastomosis formed from:
The plantar arch supplies the underside, or sole, of the foot.
The arch is formed when the lateral plantar artery turns medially to the interval between the bases of the first and second metatarsal bones, where it unites with the deep plantar branch of the dorsalis pedis artery, thus completing the plantar arch (or deep plantar arch).
The spring ligament, long plantar ligament, short plantar ligament, and plantar aponeurosis also support the plantar arch. The tibialis anterior and posterior tendons also help to pull the arch up.
