Any of the muscles that attach the upper arm and shoulder bones to the front walls of the chest are known as pectoralis muscles. The pectoralis major and pectoralis minor are two such muscles that are located on either side of the sternum (breastbone) in the human body.


The larger and more superficial pectoralis major muscle has its origins in the sternum, ribs, clavicle, and a tendinous extension of the external oblique abdominal muscle. The pectoralis major connects to a ridge at the back of the humerus and spans the top portion of the chest (the bone of the upper arm). 


Adduction, or lowering, of the arm (against the deltoideus muscle's activity), and rotation of the arm forward about the axis of the body, are two of its main motions.
