All human beings have the same number of ribs no matter what age. We have 12, one from each of the Thoracic vertebrae. The top 6 are called the True ribs as they connect to the Sternum via an individual piece of cartilage (its Costal Cartilage). The Next 4 are called the False ribs as all their coastal cartilages of these ribs connect to another piece of cartilage not directly to the sternum. The bottom two are called the Floating ribs as they do not have any coastal cartilage. These numbers remain the same in people of any age.
