Excluding the first seven sets of ribs, the remaining five sets 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.

Ninth rib

The frontal part of the ninth rib is at the same level as the first lumbar vertebra. This level is called planum transpyloricum, since the pylorus also is at this level.^[1]
