==Bone Growth and Remodeling==
'''Short bones'''- Endochondral ossification continues in the diaphysis, until only the cartilage rim remains.
'''Short bones'''- Endochondral ossification continues in the diaphysis, until only the cartilage rim remains.
'''Long bones'''- A secondary center of ossification develops in the epiphyses.
'''Long bones'''- A secondary center of ossification develops in the epiphyses.
'''Epiphyseal Growth Plate'''- The growth plate is a transverse disc of cartilate between the two ossification centers, and allows longitudinal growth to continue to maturity. It then closes. The cartilage of the epiphyseal growth plate is divided into: (from right to left on the magnified image)
