Describe the process of endochondrial ossification after birth
Autor: Nontoe NonoeRespuesta:
-Clusters of osteoblasts form in the epiphyses (ends) of the bones, forming the secondary ossification centers -The secondary ossification centers in the epiphyses are separated from the primary ossification center in the diaphysis by a layer of cartilage called the epiphyseal plate. -As calcification of the chondrocytes in the cartilage progresses outward from the ossification centers, the epiphyseal plate is pushed outwards from the centers. -Eventually, the plate can no longer be shifted, and will also become calcified, closing the space between the epiphyses and diaphysis. -Once this happens usually (late in teens) bones can no longer grow in length but only in thickness(appositional growth)
