Chapter 12: Review Sheet
1. List the organs of the nervous system.
2. Define and list the organs in the Central Nervous System and Peripheral Nervous
System.
3. List and discuss the 3 primary functions of the nervous system.
4. Discuss how the primary functions of the nervous and endocrine systems are alike
and different.
5. List the 2 MAJOR types of cells in the nervous system.
6. Define and give numbers of glia.
7. Discuss the 5 types of glia (neuroglia).
8. Define and give numbers of neurons.
9. Discuss general information about the structure of a neuron (p.membrane,
cytoplasm, and cytoskeleton (neurofibrils).
10. List the 2 MAJOR parts of a neuron.
11. Discuss the cell body (and nissl bodies) as well as the 2 types of processes (nerve
fibers) of a neuron.
12. Discuss covering(s) of axons, including how these coverings are formed. Which
axons don’t have coverings? Tell the name of these axons and why they have no
coverings.
13. Discuss the function of the neurilemma. Which axons have a neurilemma?
14. List and discuss 3 types of neurons based on structure.
15. List and discuss 3 types of neurons based on function.
16. Tell how structural and functional classifications go together.
17. Define gray matter, nuclei, and ganglia.
18. Define white matter, tracts, and nerves.
19. Discuss 3 connective tissue components and 3 types of nerves.
20. Define and discuss 2 types of reflex arc pathways (reflex arcs).
21. Define, list 2 types of, and discuss the importance of reflexes.
22. Give examples of other pathways (besides reflex arcs) in the nervous system.
23. Discuss 5 generalizations about the nerve impulse.
24. Describe saltatory conduction. Which nerve fibers conduct using salutatory
conduction?
25. Discuss conduction of nerve impulses along plasma membrane (electrical events).
Include in the discussion the following: a) Resting Membrane Potential
(Polarization), b) Stimulus, c) Action Potential (Nerve Impulse/Reverse
Polarization, d) Repolarization, and e) Refractory Periods (Absolute and
Relative).
26. List the location of synapses and discuss the structure of chemical synapses.
27. Discuss the mechanism of chemical conduction across synapses.
