The Radial artery arises from the brachial
artery near the neck of the radius. It first runs on the superior border of
the pronator teres and then deep to the brachioradialis muscle. The entire length
of the artery is visible when the brachioradialis muscle is pulled laterally.
It leaves the forearm by winding around the lateral aspect of the wrist. It
crosses the floor of the anatomical snuffbox. It is the primary contributor
to the deep palmar arch.
The common place for measuring the radial pulse rate is on the anterior surface of the distal end of the radius, lateral to the tendon of the flexor carpi radialis.
