The thoracic, or chest wall, consists of a skeletal framework, fascia, muscles, and neurovasculature – all connected together to form a strong and protective yet flexible cage. the thorax has two major openings: the superior thoracic aperture found superiorly and the inferior thoracic aperture located inferiorly. the superior thoracic.

The muscles that make up the thorax wall include the three intercostal muscles (external, internal, and innermost), the subcostalis, and the transversus thoracis. eleven pairs of intercostal muscles are in each of the intercostal spaces, arranged from superficial to deep. the most superficial layer is the external intercostal muscle, which. This is called the transversus thoracis muscle. this muscle originates inferiorly on the body of the sternum and also on the xiphoid process and it originates on some parts of these costal cartilages. it inserts internally on ribs 2 6, on the costal cartilages of ribs 2 6. its function is to pull the ribs down.
