Question

What are the differences between true ribs false ribs and floating ribs?

Answer 1

True ribs are the first seven pairs that are connected to the sternum by cartilage. Pairs 8, 9, and 10 are false ribs as they don't join the sternum but are connected to the 7th rib by cartilage. The 11th and 12th pairs are floating ribs, they are half the size of the others.

Hope this helps!

Answer 2

Seven pairs are called true ribs. Each rib is attached to the breastbone in the front and curves around to join on to one of the vertebrae that make up the backbone via a strip of costal cartilage.

There are three pairs of false ribs. These are attached to vertebrae but are not linked to the breastbone. Instead, each rib is attached to the rib above it by cartilage.

There are two pairs of floating ribs. These are attached only to the vertebrae of the backbone.
