Shoulder Joint Anatomy Diagram - Sternoclavicular, Acromioclavicular & Glenohumeral Joints #2268180 (License: Personal Use)

The image is a schematic cross-section of the human thoracic and shoulder region, illustrating the skeletal framework involved in shoulder articulation. Point A indicates the manubrium of the sternum, where the clavicle attaches at the sternoclavicular joint; point B marks the acromion process of the scapula, forming the acromioclavicular joint with the clavicle; and point C identifies the glenoid cavity, the socket of the scapula that articulates with the humeral head in the glenohumeral joint. The ribs and costal cartilages are also visible, providing context for thoracic stability.

This image is commonly used in medical education, physical therapy resources, orthopedic reference guides, and patient-facing materials explaining shoulder injuries (e.g., dislocations, AC joint separations). It supports user intent to understand shoulder biomechanics, diagnose pain sources, or study musculoskeletal anatomy.
