What is the function of the cerebrospinal fluid?

it protects the central nervous system from being jarred

5

Neurons are what?

highly specialized cell that receive and transmit information from one area of the body to another

b. change function and structure
c. change structure but not function
d. change function but not structure

b. change function and structure

8

Which of the following is TRUE of glial cells?
a. they are usually larger that neurons

c. they help enhance the speed of communication
between neurons
d. they are both located in the cell body of every
neuron

c. they help enhance the speed of communication
between neurons

9

The part of the neuron that carries messages to other cells in the body is what?

axon

10

The phrase white matter in the brain refers to what?

myelinated axons

11

Functional plasticity:
a. can occur in children prior to about the age
seven
b. has been demonstrated in research with primates
but not with humans
c. refers to the brain's ability to shift
functions from damaged to undamaged areas of
the brain

c. refers to the brain's ability to shift
functions from damaged to undamaged areas of
the brain

12

In humans, electrical stimulation of the amygdala produces what?

feelings of fear

13

The primary function of the myelin sheath is to do what?

insulate the axon and increase the speed at which neurons convey their message

14

According to the Critical Thinking box in the text, "'His' and "Her" Brains?"

female brains conclusively support the belief
that men and women think and reason differently
b. physiological gender differences are innate,
biological, permanent, and hard-wired in the
brain

differences between make and female brains

c. not all structural differences found in male
and female brains lead to differences in
measurable behavior or abilities
