Shoulder Anatomy

The shoulder joint is one of the most complex and flexible joints in the human body, allowing a wide range of movements. It is a ball-and-socket joint where the head of the humerus (upper arm bone) fits into the glenoid cavity (shoulder socket) of the scapula (shoulder blade).

The shoulder’s mobility makes it highly functional, but also more prone to injuries, dislocations, and wear-and-tear conditions.
