Composition

The main joint of the shoulder is the one that joins the head of the humerus with the scapula, it is called the scapular humerus joint. It has two joint surfaces, one of which corresponds to the head of the humerus that has a hemispherical shape and the other is the glenoid cavity of the scapula.

These surfaces are covered by cartilage that allows a smooth and painless movement. On its outside one coating surrounding the soft tissue together, is called joint capsule is reinforced by several ligaments provide stability and prevent the bones from moving beyond its physiological limits.

A group of muscles and their tendons join the surfaces of the bones and make possible the mobility of the joint, among them the rotator cuff is very important. This is formed by 4 muscles that provide mobility and stability to the shoulder. Several transparent structures in the form of a sac called serous bags, allow the smooth sliding of the different moving components.

The shoulder is the articulation with greater amplitude of movements of the human body.
