SHORT ANSWER (Use the last blank page if you need more room)
1) State which type of muscle the following slides show. State how you know. (What evidence is there?)
[pic]
2) Draw a rough sketch of a muscle attaching to a bone. Label the muscle cells and the associated connective tissues. Which parts can you see with macroscopically? Which parts do you need a microscope to see?
3) Explain what happens microscopically when a muscle increases in size and tone.
4) Why is it unlikely that a primary cancer (uncontrolled cell growth) would occur in muscle tissue?
5) When you kick a ball, what motion are you performing at the hip, and what motion are you performing at the knee? Explain.
6) Mr.Searle drank a Pepsi, even though his wife told him it is not healthy. The proteins on the surface of some of his pancreatic cells detected an increase in blood sugar. This information was processed by the nerves of the pancreas (and to a smaller extent by the hypothalamus of the brain) which “told” the beta cells of the pancreas to release insulin. As a result, muscle and liver cells take up more glucose, thus decreasing the sugar in the blood.
A. Explain which structures in the above example are the receptor(s), control center and effector(s). (Make sure you indicate HOW you know….claim-evidence-reasoning)
B. What will happen after Mrs. Searle’s blood sugar gets closer to the middle of the normal range?
C. Is the above example negative or positive feedback? (claim-evidence-reasoning)
D. If Mr. Searle isn’t careful, his normal blood sugar regulation could become faulty. Create an example of a homeostatic imbalance (disease) that could be associated with this process. Indicate which part of the homeostatic control system (receptor-control center- effector) would be “broken” or dysfunctional in your example.
7) Give an example from the muscular system of “structure determines function.” Show how the way something is constructed makes it perfect for its “job.” (You can choose a macroscopic OR microscopic example.)
