glenohumeral joint

The glenohumeral joint, often referred to as the shoulder joint, is where the upper arm bone (humerus) meets the shoulder blade (scapula). It is a ball-and-socket joint, allowing a wide range of motion for lifting and rotating the arm. The joint is stabilized by a group of muscles and tendons known as the rotator cuff. This complex structure enables activities like throwing, reaching, and lifting, but it can also be prone to injuries due to its mobility. Proper strength and flexibility are important for shoulder health and function.
