Where does the posterior tibial artery terminate?

The correct termination point of the posterior tibial artery is at the lower border of the popliteus muscle. This is a key landmark in understanding the anatomy of the arteries in the lower leg. The posterior tibial artery, which branches from the popliteal artery, travels down the leg and runs posteriorly to the tibia. It reaches the lower border of the popliteus muscle, which is located in the back of the knee.

From this point, the artery continues into the foot, where it branches into the medial and lateral plantar arteries, providing crucial blood supply to the muscles and skin of the foot. Understanding the anatomy and flow of this artery is vital for applications such as surgeries, managing injuries, and treating vascular conditions in the lower extremities, making knowing its termination point especially important for medical professionals.
