1. Skeletal & Muscular Systems
Form and Movement

2. Engage What is Osteoporosis?????
Complete the osteoporosis questionnaire.

3. Engage
Deboned
What would happen if humans did not have bones? Your body would be limp like a rag doll. Could you stand up? Could you walk?
Without bones in your body, you would be like the blob.
As a class we will observe two bones that were soaked in two different solutions.

4. Deboned
Similarities
Differences

5. Explore The Calcium Test
Students will test various types of materials to determine the presence or absence of calcium.

6. Explore Computer Lab http://www.medtropolis.com/VBody.asp
You will visit the above website and answer questions while navigating through the narrated skeletal system section

7. Explain What are the 5 Main Functions of the Skeleton
provide structure and support for body
protect internal organs
make blood cells
store minerals
attachment for muscles for movement

8. Skeletal Systems
Exoskeleton
Endoskeleton

9. Exoskeleton external skeleton Arthropods and Mollusks
Arthropod’s skeleton is made of a material called chitin and must be shed to permit growth.
Mollusk’s skeleton is made by the mantle from calcium carbonate.

10. Endoskeleton Internal skeleton Grows with the organism
Made of cartilage or a combination of cartilage and bone.
Ossification – replacing cartilage with bone around 7 months before birth
Osteoclasts – break down bone
Osteoblasts – form bone tissue
Contains 2 parts : axial and appendicular areas.

11. Appendicular Skeleton
Skull
Sternum
Ribs
Vertebral column
Metatarsals
Metacarpals
Phalanges
Clavicle

13. Structure of Bones Solid network Living cells Protein fibers
Deposits of Calcium Salts

14. Part of Bone 1. Marrow 2. Periosteum - Outer connective tissue – tough
Yellow – fat cells
Red – RBC, WBC, Platelets
2. Periosteum - Outer connective tissue – tough
3. Compact bone
Haversian Canals
Tubes carrying blood vessels and nerves
4. Spongy bone
Less dense; inside compact bone; ends of long bones and middle of short, flat
