rib
Etymology: AS, roof
one of the 12 pairs of arches of bone forming a large part of the thoracic skeleton. The first seven ribs on each side are called true ribs because they articulate directly with the sternum and vertebrae. The remaining five ribs are called false ribs. The first three attach ventrally to ribs above. The last two are free at their ventral extremities and are called floating ribs. True ribs are also known as vertebrosternal ribs; false ribs as vertebrocostal ribs; and floating ribs as vertebral ribs. See also thorax.

Patient discussion about rib.
Q. What causes cramps in, under and around the rib cage?
A. Im not really sure, but you may have IBS. Irritable bowel syndrome or IBS affects up to 55 million Americans, mostly women. IBS causes are unknown. IBS symptoms include diarrhea, constipation, and abdominal cramps. There are IBS treatments such as diet and lifestyle changes and medications that can help. Do you have any of these symptoms? Almost everything that i found with rib cage pain said something about IBS. Not really sure if this is your problem, but I hope this helps.
