16. Ossification Formation of bone Intramembranous: bone develops between fibrous connective tissue Ex: skull Endochrondral: cartilage breaks down and lays down spongy bone which thickens and becomes compact Epiphyseal plate band of cartilage between primary and secondary ossification sites Rate of growth is controlled by hormones When the plates close growth stops
