Description[edit | edit source]
The flexor carpi radialis muscle is a long, superficial muscle of the forearm that belongs to the anterior muscle group and lies in the first layer. It is a relatively thin muscle located on the anterior part of the forearm. It arises in the humerus epicondyle, close to the wrist area. It is a superficial muscle that becomes very visible as the wrist comes into flexion.
Origin[edit | edit source]
he flexor carpi radialis originates from the medial epicondyle of the humerus, passes obliquely downwards to the lateral side of the forearm.
Insertion[edit | edit source]
The flexor carpi radialis inserts at the bases of the second and third metacarpal bones.
Nerve[edit | edit source]
The innervation of this muscle is provided by the median nerve and it receives its blood supply through the radial artery.
Artery[edit | edit source]
Function[edit | edit source]
The main function of FCR is providing flexion of the wrist and assisting in abduction of the hand and wrist. The flexor carpi radialis (FCR) muscle has been suggested to act as a dynamic scaphoid stabilizer. Because the FCR tendon uses the scaphoid tuberosity as a pulley to reach its distal insertion onto the second metacarpal, it has been hypothesized that FCR muscle contraction generates a dorsally directed vector that resists the scaphoid from rotating into flexion[1].
