Shoulder Joint with Rotator Cuff - 5 part

Function and Applications

This shoulder joint 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 shoulder joint model also shows the origin and insertion points of the shoulder muscles highlighted in color (origin = red, insertion points = blue). The following muscles of the shoulder can be depicted and even detached for a clearer understanding of the shoulder joint:

• M. subscapularis
• M. supraspinatus
• M. infraspinatus
• M. teres minor

Upon detaching the individual muscles, all movements of the shoulder joint can be carried out, namely:

• Abduction
• Adduction
• Inner rotation
• Outer rotation
