    The function of the elbow joint is to extend and flex the arm. [18] The range of movement in the elbow is from 0 degrees of elbow extension to 150 degrees of elbow flexion.

    Between these two bands a few intermediate fibers descend from the medial epicondyle to blend with a transverse band which bridges across the notch between the olecranon and the coronoid process. This ligament is in relation with the triceps brachii and flexor carpi ulnaris and the ulnar nerve , and gives origin to part of the flexor digitorum ...

    On a person's distal forearm, just before the wrist, there are either two or three tendons. The tendon of the flexor carpi ulnaris is the most medial (closest to the little finger) of these. The most lateral one is the tendon of flexor carpi radialis muscle , and the middle one, not always present, is the tendon of palmaris longus .

They are called extrinsic because the muscle belly is located on the forearm. The intrinsic group are the smaller muscles located within the hand itself. The muscles of the hand ...
