Origin and insertion
This muscle originates on the medial epicondyle of the humerus. It runs just laterally of flexor digitorum superficialis and inserts on the anterior aspect of the base of the second metacarpal, and has small slips to both the third metacarpal and trapezial tuberosity.
On the anterior aspect of a person's forearm, proximal to the wrist, flexor carpi radialis is the most lateral (closest to the thumb) tendon visible when the wrist is brought into flexion.
