Nervous System

1. Neurons that conduct nerve impulses from the receptors to the central nervous system are
motor neurons.
efferent neurons.
interneurons.
sensory neurons.

2. Processes that carry nerve impulses away from the cell body are called
dendrites.
axons.
synapses.
myelin sheaths.

3. The neuroglia that produce myelin sheaths around axons in the peripheral nervous system are
Schwann cells.
oligodendrocytes.
microglia.
astroctyes.

4. The portion of the nervous system that is considered involuntary is the
somatic nervous system.
sensory nervous system.
autonomic nervous system.
motor nervous system.

5. All of the following are functions of the nervous system EXCEPT
senses changes.
analyzes changes.
stores calcium.
responses to changes.

6. The different charge between the outside and the inside of a neuron at rest is called
action potential.
synaptic potential.
resting membrane potential.
equilibrium potential.

7. The stage in an action potential that immediately follows depolarization is
polarization.
repolarization.
threshold.
the resting period.

8. The junction between two nerve cells is called
neuromuscular junction.
