What do you know?
Write down the first 5
things that come to
mind when you think of
the skeletal system
1.02 Remember the structures
of the skeletal system
Essential Standards:
• What is the process of bone formation?
• What are the structures of the long
bones?
• What are the structures of the skeletal
system?
1.02 Remember the structures of

4
Bone formation
Identify the osteocytes.
Osteo = bone
Cyte = cell
Microscopic mature bone cells
1.02 Remember the structures of
the skeletal system
5
Bone formation

Ossification – new minerals deposit to form
bone

Discuss the process of ossification?

How do we know ossification occurs?

Example
1.02 Remember the structures of

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.

Bone formation



How do we know ossification occurs?
Long bones grow in length and ossify from the
center to the ends.
Give examples of ossification.
