The radial artery is one of the two major blood vessels in the forearm. It lies next to the radius bone, hence its name. Not only does the radial artery supply blood to the forearm, hand, and fingers, it is also medically significant because it is close to the surface and easy to access.


1. A Branch of the Brachial Artery

The brachial artery is the main blood supply for the arm. It begins right around the axilla or armpit and continues to the elbow. From there, it splits into two branches: the ulnar and radial arteries. The radial artery lies on the lateral side of the forearm, running from the elbow down to the thumb and continuing into the hand.
