Number of Ribs Connected to the Sternum with Cartilage

The number of pairs of ribs that are connected to the sternum with cartilage varies among individuals. In most cases, there are seven pairs of ribs that are directly connected to the sternum with cartilage. These are known as the true ribs or vertebrosternal ribs.

However, there are also additional pairs of ribs that are indirectly connected to the sternum through the cartilage of the higher ribs. These are known as the false ribs or vertebrochondral ribs. There are typically three pairs of false ribs that are connected to the sternum with cartilage.

In addition to the true and false ribs, there are also two pairs of floating ribs that are not connected to the sternum at all. These ribs are only attached to the vertebrae at the back and do not have any cartilaginous connection to the sternum.

Therefore, in total, there are typically twelve pairs of ribs in the human body, with seven pairs of true ribs connected to the sternum with cartilage, three pairs of false ribs indirectly connected to the sternum, and two pairs of floating ribs.

Please note that individual variations may exist, and the number of ribs connected to the sternum with cartilage can vary slightly from person to person.
