The radial artery is a major artery in the forearm, located on the thumb side. It is a continuation of the brachial artery, which branches off from the axillary artery in the armpit. The radial artery supplies blood to the muscles and tissues of the forearm, including the hand.

The radial artery is typically palpable in the wrist, where it can be felt as a prominent pulse. It runs down the forearm, passing through the radial tunnel, a narrow space in the forearm that contains the radial nerve. The artery then continues into the hand, where it becomes the superficial palmar arch, which supplies blood to the palm and fingers.

The radial artery is an important landmark in anatomy and is often used as a reference point for various medical procedures. It is also a common site for the insertion of intravenous (IV) catheters, as it is easily accessible and has a high blood flow rate.

In some cases, the radial artery may be affected by certain medical conditions, such as atherosclerosis or peripheral artery disease. These conditions can lead to a reduction in blood flow to the hand and fingers, causing symptoms such as pain, numbness, and weakness. In severe cases, surgery may be required to restore blood flow to the affected area.
