Flexor carpi radialis
The flexor carpi radialis (Latin: musculus flexor carpi radialis) is a long fusiform-shaped superficial muscle of the upper limb that extends between the humerus and the metacarpal bones. It is one of the wrist flexors and belongs to the anterior muscles of the forearm. It lies in the first (superficial) layer of the anterior forearm compartment.
|Flexor carpi radialis|
|Origin||Medial epicondyle of humerus|
|Insertion||Bases of 2nd and 3rd metacarpal bones|
|Action||Flexion and abduction of wrist|
|Innervation||Median nerve (C6, C7)|
|Blood supply||Anterior or posterior ulnar recurrent arteries, branches of radial artery|
The flexor carpi radialis originates from the medial epicondyle of the humerus and further goes obliquely downward to the radial side of the forearm.
The flexor carpi radialis inserts at the bases of the second and third metacarpal bones.
The flexor carpi radialis muscle provides the flexion and abduction of the wrist at the wrist joint.
The flexor carpi radialis is innervated by the median nerve (C6, C7) - a branch of the brachial plexus.
The flexor carpi radialis muscle receives arterial blood supply from the anterior or posterior ulnar recurrent arteries that arise from the ulnar artery. Besides the mentioned arteries, this muscle is also supplied by the branches of the radial artery. The radial artery branches off the brachial artery.
