5. Bone formation

 How do we know ossification occurs?
 Example
1.02 Remember the structures of
the skeletal system 5

6. Bone formation
 Ossification –
 Minerals replace previously formed cartilage.
 Infants bones are soft and pliable because of
incomplete ossification.
 As bones ossify, they become hard.
