Flexor carpi radialis muscle

In anatomy, flexor carpi radialis is a muscle of the human forearm that acts to flex and abduct the hand.

This muscle starts at the medial epicondyle of the humerus (as does flexor carpi ulnaris[?]) and attaches to the anterior side of the base of the 2nd metacarpal.

It runs just laterally of flexor digitorum superficialis, and the tendon of flexor carpi radialis can be seen on the anterior of the distal forearm.

On a person's distal forearm, right before the wrist, they will see either two or three tendons. Flexor carpi radialis is the most lateral (closest to the thumb) of these. (The most medial one is flexor carpi ulnaris[?], and the middle one, if it exists is palmaris longus[?].)

As are most of the flexors of the hand, FCR is innervated by the median nerve. It gets its blood from the ulnar artery[?].
