Detailed explanation-1: -The pectoralis major (from Latin pectus ‘breast’) is a thick, fan-shaped or triangular convergent muscle of the human chest. It makes up the bulk of the chest muscles and lies under the breast.
Detailed explanation-2: -The pectoral region is the anterior region of the upper chest where there are four thoracoappendicular muscles (also known as the pectoral muscles): pectoralis major. pectoralis minor. subclavius.
Detailed explanation-3: -You have two pectoralis majors or “pecs, ‘’ one on each side of your chest. These large muscles help you move your shoulder. These muscles help pull your arm across the front of your body. Injury to the pectoralis major can cause shoulder pain and limit your ability to use your arm fully.
