The posterior tibial artery is primarily responsible for supplying blood to the posterior compartment of the leg. This artery branches off from the popliteal artery and runs down the posterior aspect of the leg, giving rise to several branches that nourish the muscles and tissues located in this compartment. The posterior compartment includes muscles that are responsible for plantar flexion of the foot and toe flexion, which are crucial for activities such as walking and running.

In contrast, the other areas mentioned in the options are supplied by different vessels. The front of the leg is primarily supplied by the anterior tibial artery, while the medial side of the foot receives blood from branches of the posterior tibial artery, but not predominantly as the posterior compartment does. The lateral side of the thigh is served by branches of the femoral and profunda femoris arteries. Therefore, understanding the specific vascular supply of each compartment helps clarify the anatomical and physiological roles of these arteries.
