It makes up the bulk of the chest muscles and lies under the breast. Beneath the pectoralis major is the pectoralis minor muscle. The pectoralis major arises from parts of the clavicle and sternum, costal cartilages of the true ribs, and the aponeurosis of the abdominal external oblique muscle; it inserts onto the lateral lip of the bicipital ...
A similar effect, known as the 'bucket handle movement' causes the transverse diameter of the chest to increase, because not only do the ribs slant downwards from the back to the front, but, in the case of the lower ribs, also from the midline downwards to the sides of the chest. The human rib cage is a component of the human respiratory system ...
