The pectoralis (pec) muscles are large, highly visible muscles located on each side of the chest. Their primary job is help the shoulders and arms move and lift.

Pectoralis muscle. Pectoralis muscle, any of the muscles that connect the front walls of the chest with the bones of the upper arm and shoulder. There are two such muscles on each side of the sternum (breastbone) in the human body: pectoralis major and pectoralis minor. The pectoralis major, the larger and more superficial, originates at the clavicle (collarbone), the sternum, the ribs, and a tendinous extension of the external oblique abdominal muscle.
