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.
Pork ribs
Button ribs (or "feather bones") are often confused with riblets mostly because Applebee's sells these as "riblets". In fact, what Applebee's sells is found just past the ribs near the back bone, just underneath the tenderloin. This cut of meat actually has no bones, but instead has "buttons" of cartilaginous material with meat attached.
