Shoulder joint

The shoulder joint, also known as the glenohumeral joint, is a ball-and-socket joint formed by the articulation between the head of the humerus (the upper arm bone) and the glenoid cavity of the scapula (the shoulder blade). This joint allows for a wide range of motion in various directions, including flexion, extension, abduction, adduction, internal rotation, and external rotation. It plays a crucial role in the mobility and function of the upper limb.
