Extensor carpi radialis brevis muscle

From Freepedia

The extensor carpi radialis brevis is specific human muscle. It is an extensor, and an abductor of the hand at the wrist joint.

It lies medial to longus, and is slightly shorter. It starts lower down on the humerus at the lateral epicondyle, and inserts into the base of the 3rd metacarpal.

Like all the muscles in the posterior forearm, ECR brevis is supplied by a branch of the radial nerve.
