The bones of the shoulders are covered by a tissue called cartilage, the smooth surface of the cartilage allow for smooth movement and pain-free shoulder. The ligaments being to connect the bones and help keep the shoulder in place. This conformation allows the muscles involved to move the shoulder in all directions.
