20/09/1 Greausth of Bone c)During child hoogd cepto adolescenc naveer in lentoth and three the bone frосеем bout the body the bane grow in thid) Guouwth in lenith It involves tuo major event. 1) The intentitial quouth of cartilage. epiphyseal plate. 2) The Meplacement of cartilage in the epiphyseal plate by andochondral essification. The epiphyseal plate prouth is a rayer of hyline cartilage consist of 4 different zones- a) Zone of Resting cartilage:- The game succeeds because the call present here isn't used in bone δικαι. The layer is inner to the epiphysis and contains chondrocytes. 6) The cone of prolifinating cartilage:- theree the Chondrocytes are slightly langer & arranged as as Chondrogynes divide & secret This Ch extracellular matrix c) Rone of hypertropic Cartilage: This layer consist of mature Chondrogfles 2) Zone of calcified cartilage:- In this cone the chondrocytes are almos doad The osteoblast dissolved the calcified cartilage they lay down in bone extracellular matray therr they Meplace the calcified cartilage by endochondral ossification process. As Result the cone calcified cartilage become the new diphyses which lie in the reest of the diphysis zono in In case of ow at the age of case of at the age of 21, the epiphygead frearth plate stop dividimpes bones replace all the epiphyseal cartilage
