Document Summary

Ulna when talking about the bone vs. ulnar when referring to a position. Radial annular ligament: loops from ulnar anteriorly around radial head and attaches to the ulnar posteriorly. Distal tendon of biceps brachii muscle attaches to radial/bicipital tuberosity of radius. Oblique cord variable structure (prominent in some and subtle in others) little function in modern human. Trochlear notch connects between coronoid process and olecranon process. Radial annular ligament attaches anteriorly to ulnar near coronoid process and posteriorly. Fibrocartilaginous doesn"t attach to radial head facilitates smooth movement of radial head. Ulnar (medial) collateral ligament has narrow attachment to medial epicondyle and large, broad attachment to ulna. Bicipital bursa protects the bone and tendon from damaging each other as distal tendon attaches to radial tuberosity on the radius. Large medial epicondyle provides attachment for ulnar collateral ligament -> attaches to large area on medial side of ulna. Radial collateral ligament: from small lateral epicondyle and attaches into the radial annular ligament.
