2 Ways Bone grows and develops


Embryonic Development of bone


 For one thing, we all know that if we eat right, our bones will prosper and grow. They develop embryonically or postembryonically. Embryonic development are cells that are not specific changing to more specific cells.These cells make new tissues and organs for the body. 

Two ways that these bones can grow in the Embryonic stage intramembranous ossification and endochondral ossification. In intramembranous  ossification, the bones change inside the membrane. In endochondral ossification forms by replacing hyaline cartilage.



                                                


Postembryonic Development of bone

 Postembryonically is any change after one if born. An example would be a boy growing taller. To make the bones wider, more compact bones must be placed outside the edge of the bone.
