The anterior tibial artery is an artery of the leg. It carries blood to the anterior compartment of the leg and dorsal surface of the foot, from the popliteal artery.
The anterior tibial artery is one of the terminal branches of the popliteal artery. It arises below the popliteal fossa , in the posterior (flexor) compartment of the leg . However, the majority of its course is located in the anterior (extensor) compartment of the leg.
The anterior tibial artery supplies blood to the front of the lower leg and becomes the dorsalis pedis artery at the ankle, as well as branching off into other vessels that serve the lower leg. The anterior tibial artery itself first branches off from the popliteal artery found behind the knee.
Posterior tibial artery – continues inferiorly, along the surface of the deep posterior leg muscles (such as tibialis posterior). It enters the sole of the foot via the tarsal tunnel, accompanying the tibial nerve.
The anterior tibial artery is a branch of the popliteal artery. It arises at the lower border of the popliteus muscle in the posterior leg. After its origin, the anterior tibial artery passes through a gap in the interosseous membrane to enter the anterior compartment of the leg.
The posterior tibial artery is a branch of the popliteal artery that supplies the posterior compartment of the leg and the sole of the foot. It is located in the posterior compartment of the leg, coursing from the inferior margin of the popliteus muscle up to the medial malleolus.
Anterior tibial artery The popliteal artery divides and gives off an anterior tibial branch that supplies the anterior compartment of the leg i.e. tibialis anterior, the extensor hallucis longus and extensor digitorum longus muscles.
The anterior tibial artery passes anterior to the popliteus muscles and passes between the tibia and fibula through the interosseous membrane. Once through the interosseous membrane, the anterior tibial artery travels between the tibialis anterior and extensor digitorum longus muscles.
The anterior tibial artery courses inferiorly along the interosseous membrane and lateral to the tibialis anterior muscle. It then passes in front of the ankle joint and continues as the dorsalis pedis artery onto the dorsum of the foot.
The tibial arteries include the anterior tibial artery and the tibioperoneal trunk, which bifurcates into the peroneal and posterior tibial arteries. Division of the soleus muscle longitudinally helps expose the origin of the tibial arteries.
