38
Infraspinatus action
External rotation of humerus SITS muscle
39
Teres minor action
External rotation of humerus, SITS muscle
40
Pectoralis major action
Adduction, internal rotation of humerus, pulls scapula forward. Clavicular head alone flexes humerus, sternal head alone extended from flexed
41
