The chest wall (thoracic cage) is composed by twelve pairs of ribs laterally and the sternum anteriorly. The ribs are attached to the dorsal vertebrae (thoracic spine) posteriorly and along their costal cartilage to the sternum.
The thoracic cage main function is to protect the vital chest organs such as the heart and lungs.
There are five muscles that make up the thoracic cage; the intercostal (external, internal and innermost), subcostals, and transversus thoracis.
