Our shoulders include some of our most commonly used muscles, including the rotator cuff, latissimus dorsi, teres major, trapezius, and the pectoral girdle. They support weight, help us move and push items, as well as assist with actions of the trunk of the body. The area is dense with smaller muscles, ligaments, and muscular attachments. Because of the complexity of this area, it is important for medical professionals and students to have a firm understanding of the shoulder and its muscles. With these muscled shoulder joint models, it becomes easier to have a visual and tactile understanding of the area.
