Dendrite
Which of the following is true of Schwann cells?
Schwann cells provide myelin for peripheral nerve

A neuron membrane potential moves from -90 mV to -80 mV in response to a brief
stimulation. We would term this change in potential as a(n)
depolarization.
Which of the following is true of ion distribution across the axon membrane in the
resting state?
Sodium ions are more concentrated outside the axon membrane.
The Na+/K+ pump removes
3:2
Quiz 3
The difference in electrical charge between the inside and the outside of the axon
membrane is defined as the
potential.

Which of the following events restores the membrane potential from the peak of the
action potential back down to the resting level?
Potassium ions move out of the cell.
What is the very brief moment after a neuron reaches threshold where it will be
difficult to depolarize again?
refractory period
Which of the following was suggested as an advantage associated with myelination?
Myelin speeds up axon conduction speed.
Quiz 4
The postsynaptic potentials induced by most neurotransmitters are ended by
reuptake of the molecule into the axon terminal.
Signals are carried across the synapse as a result of
neurotransmitter release.
Match up the correct receptor type and
effect. ionotropic: direct opening of an ion
channel
An IPSP will be produced when a
ligand opens a chloride channel
The nervous system codes for variation in the intensity of incoming sensory stimuli by
variations in the or a neuron
firing rate

The term "rostral" means
toward the beak or snout.
A brain region that is anterior and dorsal to the thalamus could also be described as
and to the thalamus.

CSF flows from third ventricle to the fourth ventricle via the
cerebral aqueduct.
Quiz 6
A refers to a bulge of tissue located between the adjacent grooves in the surface of
the human cortex.
Gyrus
Which of the following would be expected as a result of damage to the somatosensory
association cortex?
Difficulty in naming an object the person can touch (but not see)
Damage to the amygdala would be expected to alter
Emotion
Damage to the basal ganglia would be expected to produce difficulties in
Motor movements
A key function of the autonomic nervous system includes the control
of "vegetative" processes.

You reach out and touch a piece of cloth, feeling its texture. The cells that gather this
sensory information are part of the nervous system.
Peripheral
A neuron first receives a message in a(n) . The message is then passed along a
thin, long portion of the cell called the .
dendrite; axon
are supporting cells that can provide myelination to multiple axons at
once. Oligodendrocytes
are glial cells that participate in phagocytosis, provide lactate for cells,
and structurally support neurons in the brain.
Astrocytes
The purpose of the blood-brain barrier is to:
block the entrance of some substances into the brain.
As you study for your neuroscience exam, you feel a tickle on your arm. You look and see a large
spider, and you jerk your arm automatically. What might be the neural path for this action?
Sensory neuron– interneuron–motor neuron– muscle
