Anterior medial malleolar artery

The anterior medial malleolar artery (medial anterior malleolar artery, internal malleolar artery) arises about 5 cm. above the ankle-joint and passes behind the tendons of the Extensor hallucis longus and Tibialis anterior, to the medial side of the ankle, upon which it ramifies, anastomosing with branches of the posterior tibial and medial plantar arteries and with the medial calcaneal from the posterior tibial.
