The shoulder is a complex joint that connects the upper arm to the torso. It consists of three main bones: the humerus, scapula, and clavicle. This joint allows for a wide range of motion, enabling activities such as lifting, throwing, and reaching. The shoulder is supported by muscles, tendons, and ligaments that help stabilize and move the arm. In addition to its mobility, the shoulder plays a crucial role in various daily activities and sports. Common injuries include rotator cuff tears and shoulder dislocations, which can result from overuse or trauma. Proper strength and flexibility exercises can help maintain shoulder health and prevent injuries.
