Human Shoulder Joint Model with Rotator Cuff and 4 Removable Muscles, 5-part

This model comprises the upper half of the humerus together with the clavicle and scapula. It shows the musculature of the rotator cuff and highlights the muscle origins (red) and insertions (blue); the four rotator-cuff muscles — M. subscapularis, M. supraspinatus, M. infraspinatus and M. teres minor — can be detached for a clearer understanding of the joint. With the muscles removed, all shoulder movements can be demonstrated, including abduction, adduction, internal and external rotation, and raising and circling of the arm. Mounted on a stand for easy display in the classroom or the doctor's office.
