Rib
Ribs are classed as flat bones which usually have a protective role in the body. Humans have 24 ribs, in 12 pairs. All are attached at the back to the thoracic vertebrae, and are numbered from 1–12 according to the vertebrae they attach to. The first rib is attached to thoracic vertebra 1 (T1). At the front of the body most of the ribs are joined by costal cartilages to the sternum. The ribs connect to the vertebrae with two joints, the costovertebral joints.
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).
