1. The peripheral nervous system:

processes and stores information.
contains the spinal cord and autonomic nervous system.
does not rely on neurons for communication.
consists of the somatic and autonomic nervous systems.

2. The role of the somatic nervous system is to:

control the skeletal nervous system associated with voluntary action.
regulate sleepiness.
mobilize the body for action.
deactivate or turn down the arousal of the sympathetic nervous system.

3. Biofeedback has been used primarily to influence the action of the :

central nervous system.
cerebrum.
autonomic nervous system.
subatomic nervous system.

4. The extending fiber that conducts impulses away from the cell body and towards other neurons:

neuronal lightning rod.
myelin sheath.
axon.
dendrite.

Refer back to page 119

5. The action potential

is the exitatory effect at the receptor site of the synapse.
moves more slowly if the myelin sheath covers the neuron.
moves more rapidly if it can pass along the glial cells that surround the neuron.
is a brief change in electrical voltage that produces an impulse.

9. Fred suffered brain damage to an area that resulted in the inability to store new information into memory (although he could recall memories stored before his injury). The structure that was damaged is most likely the:

thalamus.
hippocampus.
amgydala.
cerebrum.

10. Lateralization refers to:

the activation which arouses higher centers when something demands their attention.
the ability to tell right from left which is necessary for coordinated muscle movements like walking.
the specializations of the two hemispheres.
distribution of information to be learned into the association cortex.

11. Broca's area refers to

the region in the frontal lobe that handles speech production.
the region in the frontal lobe that handles speech comprehension.
the region in the temporal lobe that handles speech comprehension.
the region in the temporal lobe that handles speech production.

Refer back to page 132

12. Information about pressure, pain, and touch are received in which of the following?

occipital lobe.
temporal lobe.
motor cortex of the frontal lobe.
parietal lobe.

Refer back to page 132

13. The split brain experiments relied on severing what bundle of fibers that connects the two hemispheres?

limbic system.
optic chiasma.
corpus callosum.
somatosensory path.

Refer back to page 134

14. Although it has been learned that the two hemispheres work cooperatively with each other to produce our behavior, the right hemisphere is superior in:

logical tasks in problem solving.
spatial-visual ability like reading a map.
solving math problems.
processing language.

Refer back to page 137

15. Which of the following is the most likely reason left-hemispheric damage is less likely to cause language problems in women than men?

thinking is usually unrelated to speaking for women.
unlike men, women apparently use both hemispheres in some language functions.
for men, the left hemisphere is used solely for language because the right hemisphere is preoccupied with sex.
women's brains are more lateralized than men's.
