false rib
Lower thoracic bone
A false rib is one of the lower ribs that do not attach directly to the sternum.
In humans, there are five pairs of false ribs: the eighth through twelfth ribs.
The upper three pairs connect to the sternum indirectly through cartilage that joins the rib above, while the lowest two pairs, called floating ribs, have no front attachment at all.
The term distinguishes these from the true ribs, which connect directly to the breastbone.
