Supraspinatus muscle - Wikipedia
The supraspinatus muscle performs abduction of the arm, and pulls the head of the humerus medially towards the glenoid cavity. It independently prevents the head of the humerus from slipping inferiorly. The supraspinatus works in cooperation with the deltoid muscle to perform abduction, including when the arm is in an adducted position.
