Station 1

—Part 1: The arrangement of the upper and lower limbs is very similar, but with a few distinctions. Sketch a drawing of one upper limb and one lower limb next to each other. Color code the bones in each to show the similarities in structure and arrangement. Make sure to include a color coded key! Then answer the question below.

1. The similarities in the two structures should be clear in your sketches. Clarify now the differences in the structures and why these differences make it possible for the each limb to accomplish its specific functions.

– Part 2: Put one of the disposable gloves provided on your non-dominant hand. Then use the permanent markers to draw the different bones of the hand over your actual hand bones onto the glove. Use 3 different colors to show the 3 sections of the hand. Then answer the question below.

2. Refer to your glove drawing and list the 3 sections of the hand bones and how many are in each. Then classify the type of bones that are in each section. Lastly, list how each section of bones contributes to the overall function of the hand.

1. What causes the skeletal system of astronauts to become weaker overall in space? What is this due to?

2. Who else, besides astronauts, is prone to what you listed in #1? What is this disease called?

3. Bone loss happens more in the lower limbs than the upper limbs. Why do you think this is?

4. The article notes that many people think of bones as rigid and unchanging structures made of calcium, which is far from the truth. How does it describe the actual nature of bones?

5. In prolonged , bone mass appears to because the on the bones slows the formation of .

7. What is the main risk of our bones becoming more porous and fragile? Which are specifically of the most concern?

8. When are our bones at “peak bone mass”?

9. Our bones are constantly being broken done and reformed

through a process called bone remodeling. What’s different about this disease then?
