Most bones of the human body develop through endochondral ossification, which means that
ossification that occurs within a cartilage model
(Except for the flat bone of the skull which occurs via intramembranous ossification)
Physiology: bone
which is the primary and secondary ossification centers
- *primary → diaphysis**: the shaft
- *secondary → epiphysis:** end of the bone
