The extensor carpi radialis brevis is a short, wide, flattened muscle. It arises from the humerus and narrows into a long, flat tendon about two-thirds of the way down the arm. It lies between the extensor carpi radialis longus and the extensor digitorum along the outer surface of the radius. This muscle extends and radially deviates the hand at the wrist joint.
