Rib facts

A
  • 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
