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.
Meat chop
A meat chop is a cut of meat cut perpendicular to the spine, and usually containing a rib or riblet part of a vertebra and served as an individual portion. The most common kinds of meat chops are pork and lamb. A thin boneless chop, or one with only the rib bone, may be called a cutlet, though the difference is not always clear. The term "chop" is not usually used for beef, but a T-bone steak is essentially a loin chop, and a rib steak a rib cutlet.
