Long bones are first made of cartilage (A). The first center of ossification in a long bone is in the diaphysis (not the distal epiphysis) (B). Bone matrix formation proceeds from the center of the diaphysis to both ends of the bone and is not completed at birth (C). An epiphyseal disc is on the metaphysis side of a long bone, not the articular surface (D). On the diaphysis side of an epiphyseal disc, bone replaces cartilage (E). When a bone stops growing, all of the cartilage in an epiphyseal disc has been replaced by bone (F).
