What does the anterior tibial vein (ATV) drain?

The anterior tibial vein (ATV) is responsible for draining blood from the anterior compartment of the leg, which includes the muscles at the front of the leg that are primarily responsible for dorsiflexion of the foot. This vein collects deoxygenated blood from structures located in the anterior foot, including the muscles and tissues located around the dorsum (the upper surface) of the foot. Thus, the correct answer is that the ATV drains the anterior foot.

While other veins drain different areas of the foot (such as the medial, lateral, and plantar surfaces), the ATV specifically focuses on the anterior aspect, meaning it does not serve the other regions as its primary area of drainage. Therefore, the anatomical connection and role of the ATV in venous drainage are accurately reflected in the choice regarding the anterior foot.
