What artery supplies the foot, positioned laterally to the large tendon of the big toe?

The dorsalis pedis artery is responsible for supplying blood to the foot and is located on the dorsum (top) of the foot. Specifically, it can be found positioned laterally to the tendon of the big toe (the extensor hallucis longus tendon). This artery is a continuation of the anterior tibial artery, and it plays a crucial role in vascularizing the structures of the foot, including the toes. It is important for the overall circulation of the foot, enabling the delivery of oxygenated blood and nutrients necessary for the health and function of tissues. Understanding the anatomical position of the dorsalis pedis artery in relation to the extensor tendon is vital for procedures such as pulse assessment and surgical interventions involving the foot.
