The phrase floating rib (Latin: costae fluitantes) refers to the two lowermost, the eleventh and twelfth, rib pairs; so-called because they are attached only to the vertebrae–and not to the sternum or cartilage of the sternum.
Just so, can a rib bone grow back?
The periosteum contains cells that can manufacture new bone. Particularly in young people, 'rib periosteum has a remarkable ability to regenerate bone, perhaps more so than any other bone'. Thoracic (chest) surgeons routinely remove ribs, and these often grow back, in whole or in part.
What are the bones of the rib cage?
The diaphragm is attached to it's lower border. The bones of the rib cage are the sternum, the 12 thoracic vertebrae and the 12 pairs of ribs. The sternum is a flat bone that is made up of three parts, the (1) manubrium, (2) body, and the (3) xiphoid process.
What is the bone between your ribs?
The sternum, or breastbone, is a flat bone at the front center of the chest. The ribs and sternum make up what is called the 'ribcage.' The ribcage protects the lungs, blood vessels, and heart, along with parts of the spleen, stomach, and kidneys from traumatic injury.
