Pectoral muscles (colloquially referred to as "pecs") are the muscles that connect the front of the human chest with the bones of the upper arm and shoulder. This region contains four muscles that provide movements to the upper limbs or ribs. Deep muscles of the chest, including pectoralis minor, serratus anterior, and subclavius (Gray 1918)
Superficial anatomy of female and male human body Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of superficial anatomy Surface anatomy , or superficial anatomy, is important in human anatomy being the study of anatomical landmarks that can be readily identified from the ...

Internal intercostal muscles also known as intercostalis internus aid in forced expiration (quiet expiration is a passive process). They originate on ribs 2–12 and have their insertions on ribs 1–11.Their fibers pass anterior and superior from the upper margin of the rib and costal cartilage to the lower margin of the rib above.
