We just learned about the Pectoral Girdle
The lower five ribs are called the false ribs.
(From: Wikipedia - false ribs)
The upper three false ribs are called the vertebro-chondral ribs, because they connect from the vertebrae to the rib above them.
The lower two false ribs are called the floating ribs or vertebral ribs because they only connect to your vertebrae, and the other end is just floating out there.
