Answer 1

The ribs in the human body are classified into three groups: true ribs, false ribs, and floating ribs. True ribs (1-7) attach directly to the sternum via their costal cartilage. False ribs (8-12) attach indirectly to the sternum using the cartilage of the next higher rib. The last two pairs of ribs, known as floating ribs (11-12), do not attach to the sternum at all.
