Pectoralis Major Muscle Function. The pectoralis major muscle is the most important muscle for the adduction and anteversion of the shoulder joint which is why it is also known as the “breaststroke muscle”. It rotates the upper arm outwards and makes a powerful stroke movement (retroversion) when the arms are elevated (e.g. in wood-chopping).

Pectoralis muscle The pectoralis major extends across the upper part of the chest and is attached to a ridge at the rear of the humerus (the bone of the upper arm). Its major actions are adduction, or depression, of the arm (in opposition to the action of the deltoideus muscle) and rotation of the arm forward about the axis of the body.

Pectoralis major muscle The pectoralis major (/ˌpɛktəˈreɪlɨs ˈmeɪdʒər/) (from Latin: pectus, breast) is a thick, fan-shaped muscle, situated at the chest (anterior) of the human body. It makes up the bulk of the chest muscles in the male and lies under the breast in the female.he pectoralis major has four actions which are primarily responsible for movement of the shoulder joint. The first action is flexion of the humerus, as in throwing a ball side-arm, and in lifting a child.

What Is the Function of the Pectoral Girdle? In humans, the pectoral girdle, or shoulder girdle, is made up of the scapula, clavicle and various muscle groups. It functions by connecting the upper limb to the spinal column through a series of muscles in the shoulder and upper back. Continue Reading.

Injuries of the Pectoralis Major Muscle: Evaluation with MR Imaging Rupture of the pectoralis major muscle is an uncommon sports injury that is becoming more prevalent as the numbers of both professional and recreational athletes increase. Complete rupture typically occurs when the muscle is under full tension and subject to additional stress (1).

Muscles The major muscle in the chest is the pectoralis major. This large fan-shaped muscle stretches from the armpit up to the collarbone and down across the lower chest region on both sides of the chest.njuries to this muscle are rare, but symptoms include pain in the chest, bruising, and decreased strength of the muscle. The pectoralis minor resides under the pectoralis major. This thin triangle-shaped muscle runs up and down along the upper ribs. The major muscles in the upper torso of the body include:

Rib cage The rib cage is an arrangement of bones in the thorax of all vertebrates except the lamprey. It is formed by the vertebral column, ribs, and sternum and encloses the heart and lungs.n humans, the rib cage, also known as the thoracic cage, is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the pectoral girdle (shoulder girdle), forming a core portion of the human skeleton.
