Essentials of Anatomy and Physiology

10. Name the part of the cerebrum concerned with
    each of the following: (pp. 179–183)
    a. Feels the cutaneous sensations
    b. Contains the auditory areas
    c. Contains the visual areas
    d. Connects the cerebral hemispheres
    e. Regulates accessory movements
    f. Contains the olfactory areas
    g. Initiates voluntary movement
    h. Contains the speech areas (for most people)


11. Name the three layers of the meninges, beginning
    with the outermost. (p. 184)


12. State all the locations of cerebrospinal fluid. What
    is CSF made from? Into what is CSF reabsorbed?
    State the functions of CSF. (p. 184)
    13. State a function of each of the following cranial
    nerves: (p. 189)
    a. Glossopharyngeal
    b. Olfactory
    c. Trigeminal
    d. Facial
    e. Vagus (three functions)
    14. Explain how the sympathetic division of the ANS
    helps the body adapt to a stress situation; give
    three specific examples. (pp. 188–189)
    15. Explain how the parasympathetic division of the
    ANS promotes normal body functioning; give
    three specific examples. (pp. 189, 191)

The Nervous System 195

FOR FURTHER THOUGHT

1. Your friend Fred was telling a story, with eloquent
   gestures, while making a salad. He missed the
   tomato with the knife, cut his hand badly, and
   needed quite a few stitches. A local anesthetic was
   used. How might a local anesthetic stop nerve
   impulses? (Remember that a nerve impulse is very
   simple.) What part of Fred’s brain got him into
   trouble?


2. Some pesticides kill insects by interfering with
   cholinesterase. We have cholinesterase too, and
   may be adversely affected. What would be the
   symptoms of such pesticide poisoning?


3. We cannot live without a central nervous system.
   Describe all the ways in which the central nervous
   system is protected.


4. Older drivers are sometimes said to have “lost their
   reflexes.” Is this really true? Explain.


5. Look at Question Figure 8–A. Starting at the top
   of column A, read the words down as fast as you
   can. For column B, start at the top and name the
   colors as fast as you can. Did you have any trouble?

Now column C: Start at the top and name the col-

ors—do not read the words—as fast as you can.

Was there any difference? Explain why.
