Posterior View of the Shoulder Girdle by DrummerGirl375 Posterior View of the Shoulder Girdle by DrummerGirl375
A posterior view of the shoulder girdle showing three muscles: supraspinatus m., infraspinatus m., and teres minor m. They each help the humerus move in different ways:

Suprapinatus m.: 'Helps deltoid abduct arm at shoulder; stabilizes shoulder by drawing humerus toward glenoid fossa of scapula'

Infraspinatus m.: 'Laterally rotates arm at shoulder; stabilizes shoulder by drawing humerus toward glenoid fossa of scapula'

Teres minor m: 'Laterally rotates and weakly adducts arm at shoulder; draws humerus toward glenoid fossa of scapula to help stabilize the shoulder'
