Document Summary

This is composed of two joints that can be found superiorly and inferiorly. Superior = head of the radius and the radial notch on the ulna. Inferior = head of the ulna and the ulna notch on the radius. These are both classified as synovial pivot joints and allow for rotational movement about them such as pronation and supination. Annular ligament plays vital role in stabilization of the superior joint. This is also known as the radiocarpal joint. It involves the articulation between the radius and the radius, scaphoid, lunate and triquetral bones. Movements about this joint include flexion, extension, adduction and abduction (and circumduction which is a combination of these movements) Muscles of the forearm are broken down into a superficial, intermediate and deep group on the anterior and posterior of the arm, separated by the interosseous membrane. Attachments = medial epicondyle part of the ulnar shaft of the radius. Produces pronation and slight flexion of the elbow joint.
