4. Bone formation
Identify the osteocytes.

1.02 Remember the structures of

5. Bone formation
Ossification – new minerals deposit to form
bone
Discuss the process of ossification?

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.

center to the ends.
