Anterior Tibial Artery

The anterior tibial artery is one of the two arteries into which the popliteal artery divides, the other being the posterior tibial artery. It arises from behind the upper leg (tibia), near the back of the knee, and perforates the interosseous membrane at the lower border of the popliteus muscle and emerges in the front of the leg; then the anterior tibial artery runs with the deep peroneal nerve, embedded in the extensor muscles to the dorsom of the foot, where it continues as the dorsal artery of the foot. The anterior tibial artery supplies oxygen-rich blood to several muscles of the leg and foot as it gives off six branches: posterior tibial recurrent artery, anterior tibial recurrent artery, anterior medial malleolar artery, anterior artery malleolar artery, dorsalis pedis artery, circumflex fibular artery.
