11. Formation of the Bony Skeleton Endochondral Ossification Intramembranous Ossification

12. Formation of the Bony Skeleton Endochondral Ossification

13. Formation of the Bony Skeleton Intramembranous Ossification

14. Formation of the Bony Skeleton Endochondral Ossification 1.Bone collar forms around diaphysis of hyaline mold 2.Cartilage in the center of diaphysis calcifies then develops cavities 3.Periosteal bud invades the internal cavities and spongy bone forms 4.The diaphysis elongates and a medullary cavity forms 5.The epiphyses ossify

15. Formation of the Bony Skeleton Intramembranous Ossification 1.Ossification centers appear in the fibrous connective tissue membrane 2.Osteoid is secreted within the fibrous membrane and calcifies 3.Woven bone and periosteum form 4.Lamellar bone replaces woven bone, just deep to the periosteum. Red marrow appears
