Study Notes
Rotator Cuff Muscles
- The "SITS" muscles make up the rotator cuff group:
- Supraspinatus: Abductor and External Rotator
- Infraspinatus: External Rotator
- Teres Minor: External Rotator
- Subscapularis: Internal Rotator
Primary Function
- The primary function of the rotator cuff muscles as a group is to stabilize the humeral head in the glenoid fossa.
Muscle Functions
- Infraspinatus and Teres Minor have similar functions, as indicated by the caption "same functions as infraspinatus".
