The rib cage consists of [[1]] pairs of ribs and vertebrae.

The rib cage is a bony structure in the thorax that protects vital organs like the heart, lungs, and other major vessels while also serving as a framework for breathing. It is composed of the thoracic vertebrae, ribs, and sternum. 

The rib cage is made up of 12 pairs of ribs and thoracic vertebrae that are held together by ligaments like the costal ligaments and cartilage like the costal cartilage. The costal cartilage connects the ribs to the sternum, which helps to stabilize and support the rib cage.
