Posterior Tibial Artery

Arising from the popliteal artery, the posterior tibial artery is the larger of the two tibial arteries. It passes between the tendinous arch of the soleous muscle, between the superficial and deep flexor muscles. Then, the posterior tibial artery runs behind the malleolus together with the tibial nerve, and, finally, covered by the abductor hallucis, it reaches the sole of the foot. Supplying the muscles and bones of the leg and foot with oxygenated blood, the posterior tibial artery gives off three branches: the peroneal (or fibular) artery, the medial plantar artery, and the lateral plantar artery.
