Question

Quizplus · Accepted Answer

Floating ribs are so named because they do not attach to the costal cartilage or sternum at all. Instead, they are only attached to the vertebrae of the spine, making them more flexible than other types of ribs. True ribs (A) are attached directly to the sternum via costal cartilage, and false ribs (B) are attached to the sternum indirectly through shared costal cartilage.
