What do pectorals do?
The pectorals are predominantly used to control the movement of the arm, with the contractions of the pectoralis major pulling on the humerus to create lateral, vertical, or rotational motion The pectorals also play a part in deep inhalation, pulling the ribcage to create room for the lungs to expand
