The skeletal System
“I don’t know any.” is not an acceptable answer.Use complete sentences.
After listening to the PowerPoint lecture, come back here and list evidence to explain why your answer to the above question is or is not a good answer. You may also use other outside sources to help you respond.

Function
Bone strength Can absorb more load than concrete without breaking, but makes up only 20% of the body’s weight.
1. Shape & support 2. Movement3. Protect internal organs 4. Produces blood cells
Bones contain cells and tissue. New bone tissue forms as you grow.
Joints of skeleton
1. Immovable
2. Movable
Bone growth
Example: Skull (sutures)
Example: knee
The skeletal System
5. Stores materials until body needs them
A. hinge joint – forward/backward
B. Ball & socket – large range of motionExample: shoulder
allows little or no movement

Summary:
The skeletal System
Example: shoulder
Example: neckC. Pivot – one bone rotates around another
Example: ankleD. Gliding – bone slides over bone
Bone care 1. Balanced dietCalcium & phosphorusExample: milk, whole grains, leafy green veggies, eggs, and meatExercise and aerobic activitiesExamples: running, bicycling, basketball, skating, swimming, soccer, walking, and others
Bone structure
1. Compact bone 2. Spongy bone
3. Outer membrane 4. Bone marrow
5. Canals 6. Blood vessels
