needed to replace bone and to increase length of the bone. The point where the primary and secondary ossification centers meet is called the epiphyseal line. Secondary ossification occurs after birth for postnatal bone growth and continues until skeletal maturity. As bones increased in length, they are also increasing in diameter. Appositional growth, is the growth in diameter continues after longitudinal growth stops. Osteoclasts resorb old bone
