Growth of cartilage is either interstitial growth, resulting from the mitotic division and reactivation of preexisting chondrocytes, or more commonly appositional growth, resulting from the differentiation of perichondrial cells.In a growing bone, metaphysis includes a cartilaginous epiphyseal plate that allows diaphysis to grow in length. The epiphyseal plate disappears in adults leaving a bony epiphyseal line. Hence bone does not grow in length occur in adults. Bone can grow in thickness only by appositional growth resulting from the differentiation of periosteal cells. Continue reading the full post to view the animation.
