Question

Quizplus · Accepted Answer

Ribs 8 through 12 are called false ribs because they do not attach directly to the sternum, instead they attach indirectly through the costal cartilages of the rib above them. True ribs (ribs 1-7) attach directly to the sternum while floating ribs (ribs 11-12) do not attach to the sternum at all. Costal cartilages refer to the hyaline cartilage that connects the ribs to the sternum or to the cartilage of the rib above them.
