Answer:
The 8th, 9th, and 10th pairs—false ribs—do not join the sternum directly but are connected to the 7th rib by cartilage. The 11th and 12th pairs—floating ribs—are half the size of the others and do not reach to the front of the body.

The first seven pairs are attached directly to the sternum by costal cartilages and are called true ribs
