false ribs
Unattached thoracic pairs
False ribs are the five lower pairs of ribs that don't attach directly to the breastbone.
The upper three pairs connect to the sternum indirectly through cartilage shared with the ribs above; the bottom two pairs, called floating ribs, have no front attachment at all.
The term distinguishes them from the seven "true ribs" above.
