The document discusses the shoulder and elbow joints. The shoulder is a ball-and-socket joint with a shallow socket that allows loose movement. It has ligaments including the coracohumeral, glenohumeral, and transverse humeral ligaments. The glenoid labrum is a fibrocartilage rim that deepens the socket. The rotator cuff stabilizes the shoulder. The elbow joint has a capsule that completely encloses the hinge and gliding articulations. It has medial and lateral ligaments and allows for flexion-extension and pronation-supination movements.
