Which artery supplies blood to the foot and is located lateral to the large tendon of the big toe?

The Dorsalis pedis artery is the correct answer as it is the primary artery supplying blood to the foot and is situated on the dorsum, or top side, of the foot. It typically runs lateral to the tendon of the extensor halluces longus, which is the large tendon associated with the big toe. This anatomical positioning makes it essential for assessing blood flow to the foot's dorsum during medical evaluations.

The Dorsalis pedis artery branches off from the anterior tibial artery and plays a crucial role in delivering oxygenated blood to the structures of the foot, thus supporting the foot’s overall function, mobility, and health. Understanding the specific location of this artery is vital for procedures such as pulse checks, venipuncture, or when addressing foot injuries.

Considering the other options, the Femoral artery is located higher up in the thigh and supplies blood to the lower limb but does not directly supply the foot. The Posterior tibial artery also provides blood to the foot but is situated medially, posterior and not lateral to the tendon of the big toe. The Radial artery, on the other hand, is located in the forearm and does not supply the foot at all. Thus, the distinctive location and role
