Which vessel is NOT found on or near the foot?

The circumflex artery is not associated with the foot, as it primarily supplies blood to the heart and is part of the coronary circulation. In contrast, the posterior tibial artery, medial plantar artery, and dorsalis pedis artery are all crucial vessels found in or near the foot.

The posterior tibial artery branches from the popliteal artery and supplies the posterior compartment of the leg and the sole of the foot. The medial plantar artery, which branches from the posterior tibial artery, provides blood to the medial aspect of the foot. The dorsalis pedis artery, a continuation of the anterior tibial artery, runs on the dorsum of the foot and supplies blood to the top of the foot and structures there. Understanding the vascular supply to the lower limbs, especially the foot, is essential in vascular technology, as it impacts diagnostic and surgical decisions.
