Question

Vertebrosternal ribs, also known as true ribs, are directly connected to the sternum through their own individual costal cartilages, providing a distinct connection for each rib. Vertebrochondral ribs, on the other hand, are considered false ribs because they do not directly attach to the sternum. Instead, their costal cartilages are connected to the cartilage of the rib above them, leading to a shared connection to the sternum for these ribs.
