What is "posterior tibial artery"?

The posterior tibial artery is a major artery located in the lower leg that arises from the popliteal artery behind the knee. It runs down the back of the leg and divides into various branches that supply oxygenated blood to the posterior compartment of the leg, as well as the muscles, bones, and skin of the calf and foot. This artery plays a crucial role in delivering nutrients and oxygen to the tissues of the lower leg and foot, ensuring their proper function and health. It is an essential component of the circulatory system that supports mobility and overall well-being in the lower extremities.
