1. How do graded potentials and an action potentials differ in regards to nerve function?
2. What are the physiological steps leading to the generation of an action potential?

B
F
A
E
3. How are action potentials transferred between neurons?
4. What are endorphins and where are they released?
5. What advantage does myelination give to axons?
6. Name five stimuli that can cause sensory cells to generate an action potential. What are names
of these receptors?
7. How does the brain perceive a nerve that fires with high vs. low frequency upon being
stimulated?
8. How are axons arranged in peripheral nerves?
9. What are dermatomes and how are they useful in diagnostics?
10. How are coordinated movements such as catching a fly ball, and very crude movements, such as
walking, generated by the nervous system?
11. What is the main difference between a voluntary movement and a reflex?
12. Be able to label the major functional areas of the spinal cord (in cross-section).
13. Name one effect of both sympathetic vs, parasympathetic nervous system stimulation.
14. Be able to discuss how the organs of the special senses (taste, smell, vision, hearing) are able to
convert information from the environment (the presence of chemicals in solution or in the air,
light, and sound) into a stimulus that can be interpreted by the brain.
15. What are the functional differences between the ascending and descending pathways of the
spinal cord?
16. What is a concussion?
17. What is the function of cerebrospinal fluid surrounding the brain and spinal cord?
18. What is an epidural and how does it work to block pain?
19. What substances should you NOT see in the CSF when performing a spinal tap?
20. Where are memories stored?
