Shoulder Anatomy and Physiology

The human shoulder is a powerful and large anatomical structure. The hinging ball and socket joint allows for vast gains in momentum over short periods of time and is relatively versatile. The shoulder anatomy allows for many types of throwing, fine motor movement down to typing, powerful grasping, hefting objects, climbing, combat, quadruped movement, etc. The shoulder also has a large range of motion; however, this makes the shoulder prone to injury.
