The 12 pairs of ribs are further subdivided into groups that include true, false and floating ribs. The true ribs are the top seven pair of ribs, and the rib pairs numbered eight through 10 are the false ribs. The floating ribs are the 11th and 12th rib pairs. They are called floating ribs because they are solely connected to the thoracic vertebrae.
