The popliteal artery divides into two arteries known as what?

The popliteal artery is a crucial vessel located at the back of the knee. It serves as a continuation of the femoral artery and plays a significant role in supplying blood to the lower leg. When the popliteal artery reaches the lower border of the popliteus muscle, it bifurcates into two main arteries: the anterior tibial artery and the posterior tibial artery.

The anterior tibial artery primarily supplies blood to the anterior compartment of the leg, which contains muscles responsible for extending the foot and toes. Meanwhile, the posterior tibial artery supplies the posterior compartment, which is involved in actions such as plantarflexion of the foot. This division is essential for ensuring that the lower leg receives adequate blood flow for both mobility and overall health.

The other options pertain to different arterial structures or regions and do not represent the correct outcome of the popliteal artery's bifurcation. Therefore, the correct choice highlights the important anatomical transition that occurs at the knee, facilitating vital circulation in the lower extremity.
