Excluding the first seven ribs, the remaining five are false ribs.

Of these:

  • the first three (eighth, ninth, and tenth rib) have their cartilages attached to the cartilage of the rib above (vertebro-chondral):
  • the last two (eleventh rib and twelfth rib) are free at their anterior extremities and are termed floating ribs or vertebral ribs.
