Shoulder Joint with Rotator Cuff
The model shows the shoulder joint and, in addition to the individual muscles of the rotator cuff, the bone
origins and insertions of all shoulder muscles. For didactic reasons, the areas of origin and insertion of the
individual muscles are raised and colored (origin = red; insertion = blue).
The rotator cuff consists of four muscles: subscapularis muscle, supraspinatus muscle, infraspinatus mus-
cle and teres minor muscle. Each muscle is attached to its matching areas of origin and insertion and is
detachable. The muscles are made of a half-transparent, muscle-colored material, so that the correspondi-
ng areas of origin and insertion can be seen even while the muscles are attached.
The muscles of the rotator cuff have the following functions:
• Subscapularis muscle: medial rotation
• Supraspinatus muscle: abduction and lateral rotation
• Infraspinatus muscle: lateral rotation
• Teres minor muscle: lateral rotation and adduction
