[0002] The radial artery is one of the terminal branches of the brachial artery and is slightly smaller than the ulnar artery. The radial artery is about 21.2 cm long and has an outer diameter of about 0.3 cm at the starting end. After branching from the brachial artery, it runs downward and outward. First, it passes between the brachioradialis muscle and the pronator teres muscle, and then lies between the flexor carpi radialis muscle and the brachioradialis muscle. At the lower end of the radius, it obliquely passes deep to the tendons of the abductor pollicis longus muscle and the extensor pollicis brevis muscle to enter the anatomical snuffbox on the back of the hand. It passes through the first metacarpal space to enter the deep part of the palm. After branching out the main thumb artery, it anastomoses with the deep palmar branch of the ulnar artery to form the deep palmar arch.
