These diagrams display some of the main features of superficial wrist anatomy.
The wrist flexors - palmaris longus , pronator teres , Flexor carpi radialis and ulnaris - are found on the anterior arm originating on the medial epicondyle of the humerus. Medial Epicondylitis ( golfers elbow) can be diagnosed by pain on extending the wrist - this action streches these muscles.
The wrist extensors - extensor carpi radialis brevis and brevis , and extensor carpi ulnaris are located on the posterior arm , originating on the lateral epicondyle of the humerus. The supinator muscle can also be found in this region. Lateral Epicondylitis ( tennis elbow ) can be diagnosed by pain on flexing the wrist - this action streches these muscles.
