The Infraspinatus Muscle
The infraspinatus muscle is member of the rotator cuff group, which comprises the supraspinatus, infraspinatus, teres minor, and subscapularis
The rotator cuff helps hold the head of the humerus in contact with the glenoid cavity (fossa, socket) of the scapula during movements of the shoulder, thus helping to prevent dislocation of the joint.
