The pectoralis major is the large fan like muscle located on either side of the chest, originating from the sternal half of the clavical, the anterior surface of the sternum, and the cartilage of the first seven ribs, and inserting in the bicepital groove of the humerus. Therefore, its primary actions deal with movements of the shoulder joint. It adducts, flexes, and medially rotates the humerus.

The pectoralis minor works on the scapula, drawing it toward the thorax so as to increase the range of motion of the shoulder.
