1. Which structure in the basic bone; central canal, Canaliculi, osteocytest and lamella is responsible for creating bone? For providing nutrition? Explain to a little girl why the raw chicken leg bone that was cut open was full of blood.

2. Explain why tendons and ligaments take longer to heal than bone.

3. Explain why a break in a growth plate is worse.

4. If someone has a genetic mutation which makes their collagen more "stretchy" what effect do you think it would have on their bones and joints? Would these more/less likely to break or tear? Would people with this mutation be able to do unusual things? If yes, what do you think they would be? Find at least one disease related to collagen and give its name and a brief description of the disease.

5. When a bone develops an enlargement such as a tubercle, what does this indicate about the type of force placed on the bone? How does the responsiveness of bone let forensic anthropologists learn what type of activities the person with a particular bone may have done or not done? For example, consider the twin astronauts Mark and Scott Kelly. One spent a year in space, the other stayed mostly on Earth. Would you be able to tell the difference by looking at their bones? What would you expect to see and why?

6. Name an amphiarthrotic joint. What would happen if it became synarthrotic? Diarthrotic? What structures would have to change to accomplish each change?

7. Bone doesn't just function as a source of support and protection. It also plays a key role in the immune system and acts as a reservoir of key ions. First, explain how the changes you see in bone as we age are linked to the decrease in immune system function. Next, list at least two ions that are stored in bone and explain in detail how one of their levels are maintained in the blood.
