What is the cartilage that connects ribs to the sternum called?

Explanation:
Costal cartilage is the elastic cartilage that links the ribs to the sternum, forming the sternocostal joints for the upper ribs and the costochondral joints for the others. This cartilage keeps the rib cage flexible, allowing it to expand and recoil during breathing. The other options refer to structures that don’t connect the ribs to the sternum: nerves between ribs, muscles between ribs, or cartilage that lines joint surfaces elsewhere. So the cartilage connecting ribs to the sternum is costal cartilage.
