Questions and Correct Answers
(201) Which glial cell line that cavities of the brain and central portion of the spinal
cord?
✓✓~~ Ependymal
(201) What classification and type of neuron is found in the olfactory nerve?
✓✓~~ Afferent; bipolar.
(201) Which structure of the neuron transmits neural messages, and what is the
direction of the
transmission?
✓✓~~ Axon; away from cell body.
(201) The sheaths surrounding most axons of the peripheral nervous system (PNS)
are made of
what type of cell?*
✓✓~~ Schwann.
(201) The name given to the space between two Schwann cells is*
,✓✓~~ Nodes of Ranvier.
(202) What term describes a neuron with the ability to transmit an impulse, and what
initiates this
condition?
✓✓~~ Action potential; increased permeability to sodium.
(202) What term describes neural impulse conduction across the Nodes of Ranvier,
and what are
the advantages of this type of transmission?*
✓✓~~ Saltatory conduction; faster and with less energy.
(202) What factors affect the strength and intensity of a sensory or motor response?*
✓✓~~ Number of neurons stimulated, frequency of stimulation, and the number of action
potentials
transmitted.
(202) Which type of circuit allows many presynaptic neurons to synapse with a single
postsynaptic
neuron, and for what neural process is this circuit important?
✓✓~~ Convergence; integration.
, (203) What tissue layers separate the brain into hemispheres, and what other
function does it
serve?
✓✓~~ Dura mater; periosteum of the inner cranium.
(203) What condition can result from malfunction of the choroid plexus, and what
joints of a
young patient are likely to be involved?
✓✓~~ Hydrocephalus; suture.
(204) In what cross-sectional area of the spinal cord are motor neuron cell bodies
located, and
what is the color of the tissue in this area?*
✓✓~~ Anterior horn; gray.
(204) What type of neuron cell body is affected by trauma to the anterior horn of the
spinal cord's
gray matter, and what type of paralysis is likely to result?*
✓✓~~ Motor; flaccid.
(204) Upper motor neuron lesions affect which tracts of the spinal cord, and what are
the
