There are two osteogenic pathways-intramembranous ossification and endochondral ossification-but in the end, mature bone is the same regardless of the pathway that produces it. By the sixth or seventh week of embryonic life, the actual process of bone development, ossification (osteogenesis), begins. In the early stages of embryonic development, the embryo’s skeleton consists of fibrous membranes and hyaline cartilage. Compare and contrast the interstitial and appositional growth.Compare and contrast the processes of intramembranous and endochondral bone formation.Explain the growth activity at the epiphyseal plate. List the steps of endochondral ossification.Explain the role of cartilage in bone formation.List the steps of intramembranous ossification.By the end of this section, you will be able to:ĭiscuss the process of bone formation and development.
