What is the main function of the pectoralis major?
The pectoralis major extends across the upper part of the chest and is attached to a ridge at the rear of the humerus (the bone of the upper arm). Its major actions are adduction, or depression, of the arm (in opposition to the action of the deltoideus muscle) and rotation of the arm forward about the axis of the body.
What is the action of the teres major and minor?
Arm adduction: When working in synergy with teres major, latissimus dorsi and pectoralis major, teres minor adducts the arm from the abducted position (lowers it). The function of this action is to facilitate over-head upper limb movements such as pulling and throwing.

The teres minor is deep to the deltoid muscle. As a rotator cuff muscle, the teres minor stabilizes the ball-and-socket glenohumeral joint by helping hold the humeral head (ball) into the shallow glenoid cavity of the scapula (socket). The teres minor also laterally, or externally, rotate the arm at the shoulder joint.
