What parts of the body receive blood from the anterior tibial artery?

1. Lower leg and top of foot

2. Upper leg and ankle

3. Foot and heel

4. Thigh and lower back

The correct answer is: Lower leg and top of foot

The anterior tibial artery is a significant vessel that supplies blood to the lower leg and the dorsal (top) aspect of the foot. It branches from the popliteal artery, which is located behind the knee. As it descends through the lower leg, the anterior tibial artery gives rise to several smaller branches that further supply the muscles and structures of the anterior compartment of the leg. When considering the specific areas it nourishes, the lower leg is directly supplied by the anterior tibial artery as it travels downwards. Upon reaching the foot, it continues as the dorsalis pedis artery, providing essential blood flow to the top of the foot, including the toes. This anatomical pathway is critical for maintaining healthy circulation in these regions of the body. In contrast, the other answer choices specify areas that are not directly supplied by the anterior tibial artery. The upper leg is primarily supplied by branches of the femoral artery, while the ankle is not a primary target for the anterior tibial artery. Additionally, the foot and heel receive blood supply from different arteries, making those choices incorrect as well. Thus, the correct choice comprehensively captures the blood supply function of the anterior tibial artery for the lower leg and the top of the foot.
