Assignment:
1. Describe how Hank's analogy of contrasting characters in literature (foils: Hermione and Ron, Sherlock and Watson, etc...) is relevant to the autonomic nervous system (ANS).
2. What are the two divisions of the ANS?
3. What are the types of effectors that the ANS will innervate?
4. One ANS division is sometimes called the "E" division and the other the "D", which are these and why can we use these letters to describe them?
5. What are the 3 main ways that the two ANS divisions differ anatomically?
6. Define ganglia and describe the differences between the sympathetic and parasympathetic ganglia.
7. Why are there differences in the ganglia of the two divisions?
WATCH THIS VIDEO THEN ANSWER THE QUESTIONS:
8. What are the two ways that your sympathetic neurons can signal to your body that there is stress? How are these signals different and how are they the same?
9. What is the postganglionic neurotransmitter in the sympathetic nervous system that is almost always released to stimulate the effector organ? Are there any places in the body where this is not true? (you might have to watch my lecture video on "Neurotransmitters in the ANS" for this answer because Hank actually doesn't address this :)
10. How can the same chemical (neurotransmitter or hormone) cause opposite responses? Describe an example of this in your sympathetic response.
11. What are the three consequences Hank describes that can happen if your body is in a constant state of stress? Given what you know about the sympathetic nervous system describe the physiology of one of these consequences (why would it occur)?
