Rib cage
The rib cage is the arrangement of ribs attached to the vertebral column and sternum in the thorax of most vertebrates, that encloses and protects the heart and lungs. In humans, the rib cage, also known as the thoracic cage, is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the shoulder girdle to form the core part of the human skeleton. A typical human rib cage consists of 24 ribs in 12 pairs, the sternum and xiphoid process, the costal cartilages, and the 12 thoracic vertebrae.
Short ribs
Short ribs cut from the rib area near the spine (the dorsal area) are better known as "back ribs" or "dinosaur ribs". They consist of what remains of the rib in this area after the rib chop is removed. Due to the thinness of the "serratus ventralis" here, the meat on these ribs is generally intercostal muscle (e.g., the muscle between each rib).
