This shoulder joint model is composed of the upper half of the humerus, clavicle and scapula. In addition to showing anatomy of the rotator cuff, the shoulder joint model also shows the origin and insertion points of the shoulder muscles (origin points= red, insertion points = blue).
The following muscles of the shoulder can be observed and even detached for a clearer understanding of the shoulder joint:
M. teres minor
When all the muscles are detached, it depicts all physiological movements:
Raising the arms to the front of the body
Raising the arms to the back of the body
Raising the arms above the horizontal plane and “making circles with the arms”
The shoulder joint model with rotator cuff is mounted on a stand for easy presentation in a classroom or a doctor’s office.
