Bones grow in length by endochondral ossification. It begins with cartilage that acts like a model of the bone that will grow. The bone grows in length and diameter(appositional). the structure that allows this is the epiphyseal cartilage that seperates the epiphysis from the diaphysis. When the bone is fully grown this cartilage will become bone and simply the epiphyseal line.
