1. Skeletal System Warm Up: Video “Did You Know” – The Human Body!
What was one thing from the video that you learned that you “Did NOT Know” before?

2. Critical Thinking Review with a partner or group of three…
Make a list (yes that means you need to write down your ideas) of words or phrases that describe the different functions of bones.
Simply Stated: What are our bones used for?

3. Here are some possible answers you could have brainstormed with your group.
Allow for movement
Provide support – ex. There are 24 bones called vertebrae which make up your back bone. Together, these bones support your head and upper body and protect your spinal cord.
Protect other parts of your body – What do the cranium and ribs protect?
Form new blood cells
Store minerals

4. What are the living/non-living materials that make up your bones?
Your bones are made up of both living and non-living parts or structures.
What are the living/non-living materials that make up your bones?

5. Living Materials: Bone Cells Cartilage Cells Blood Vessels
Connective Tissue
Nerves (Neurons)

6. Minerals such as Calcium
Non-Living Materials
Minerals such as Calcium
What does Calcium do for our bones?
It strengthens our bones.

7. the point where two bones meet
Terms:
Joint -
the point where two bones meet
is the hardening of bones
Ossification -
- Involves the deposits of calcium between the bone cells which make the bone stronger.

8. What?!
What is this suppose to represent?
- A joint…

9. Parts of the Bone: Definitions!
Periosteum – thin , tough, and pink membrane covering the outer layer of the bone.
- It is living tissue surrounding bone and it contains red blood cells and repairs injuries to the bone.

10. Parts of the Bone: Definitions!
Articulating Cartilage -
It covers the ends of bones so that it is smooth for sliding.

11. Definitions: Spongy Bone:
It is located towards the end of your bones. It the area in your bone that absorbs shock, contains red bone marrow, and produces red blood cells.

12. Definitions:
Marrow -
soft layer of bone material located in the hollow

13. Definitions:
Bony Layer: - calcified bone
It is located below the periosteum and contains channels that are called,
Haversain Canals -

14. Haversain Canals -
Contain blood vessels that provide the bone with oxygen and nourishment for its cells.
Ossification – occurs when cartilage cells are replaced by bone cells

15. Anatomy of the Bone
Please take out your worksheet that I gave you and let’s label the parts of the bone together.
