subscapularis	origin: scapula insertion: humerus innervation: cervical nerve action: medial rotation of the shoulder
teres major and minor	origin: scapula insertion: humerus innervation: cervical nerve actions -major: extension and medial rotation of shoulder -minor: lateral rotation and adduction of shoulder
