This model consists of the upper half of the humerus, as well as the clavicle and scapula. Besides showing the musculature of the rotator cuff, the model also shows the origin and insertion points of the shoulder muscles highlighted in colour (origin = red, insertion points = blue). The following muscles can be depicted and even detached for a clearer understanding:

o M. subscapularis
o M. supraspinatus
o M. infraspinatus
o M. teres minor

Upon detaching the individual muscles, all movements of the shoulder joint can be carried out, namely:
o Abduction
o Adduction
o Inner rotation
o Outer rotation
o Raising the arms to the front of the body
o Raising the arms to the back of the body
o Raising the arms above the horizontal plane and making circles with the arms

The model is set up on a stand.
