Leg Arteries

The main artery that supplies the lower limb (thigh and leg) is the common femoral artery, which arises from the external iliac artery. In the upper part of the thigh, it gives off an important branch; the deep femoral artery. Then, it runs down along the length of the thigh as the superficial femoral artery. Just before it reaches the knee, it changes its name for popliteal artery, giving off the sural and superior genicular arteries. Right below the knee, the popliteal artery divides into the anterior and posterior tibial arteries.

Running along the anterior side of the lower leg, the anterior tibial artery projects the following branches: posterior tibial recurrent, anterior tibial recurrent, anterior medial malleolar, anterior lateral malleolar, and dorsalis pedis, which supplies the dorsal surface of the foot. The posterior tibial artery runs down along the posterior aspect of the lower leg, giving off the these branches: fibular, medial plantar, and lateral plantar arteries.
