Your Femur (thigh bone) is stronger than concrete.

• Bone is stronger, inch for inch than the steel used in skyscrapers.

• It’s about 1/4 of your height.

The jawbone is the hardest in the human body.

Locomotion

•Movement of the body or body parts from 1 place to another

Skeletal System functions

1. Movement

2. Protects organs & tissues

3. Gives body shape & support

4. Produces blood cells

5. Stores calcium and phosphorus

How many bones do we have?

•206 bones •Born with more (300)

•Fuse together as we get older

1. Compact bone = outside of bone

•Ca & P (hardness & strength)

Bone Structure

2. Spongy bone = ends of long bones for added strength

3. Marrow = inside of bone

•2 types:–Yellow marrow = fat cells

–Red marrow = produces blood cells

4. Periosteum = Tough outer membrane

•Blood vessels and nerves•Bone-forming cells

5. Canals = blood vessels and nerves

Let’s summarize…

1. Explain the process of locomotion.

2. Explain some functions of the skeletal system.

3. Explain some parts of the bones.

Determine if the following statements are true or false. If false, change the underlined word to make the correction.

1. Blood vessels and nerves travel through bone canals.

2. Yellow marrow found inside bones produces blood cells.

3. The end of long bones contains the periosteum.

4. Compact bone is found on the outside of bones.

5. Lipids give bone hardness and strength.

6. Kidney transplants are used to treat leukemia.

7. The skeletal system protects your organs and tissues.

8. The life process of transport allows your body to move from place to place.

9. Spongy bone is found at the end of long bones.

10. The tough outer membrane is known as compact bone.
