Medical Dictionary, © 2009 Farlex and Partners
ribany of the long, curved bones forming the wall of the THORAX in vertebrates, attached dorsally to the VERTEBRAL COLUMN. The anterior ribs are connected ventrally to the STERNUM in higher vertebrates and form a protective ribcage around the contents of the thorax. Ribs are connected by intercostal muscles which cause their movement during breathing in terrestrial vertebrates.

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.More discussions about rib
