Rib facts
- first pair of ribs lies deep to the clavicles and cannot be felt through the skin
- ribs increase in size toward the middle ribs with maximum size number seven
- the first seven rib pairs attach directly to the sternum via individual costal cartilages and are considered true ribs
- ribs 8-10 use the costal cartilage of rib seven and together with ribs 11-12, are considered false ribs
-ribs 11- 12 do not attach to the sternum and by themselves are considered floating ribs
