PSYC380 / Quiz: Nerve Cells, Impulses, and Brain Anatomy
UnansweredQuestion 1
pts
When you touch something, where does the conscious perception occur?
In your hand
In your brain
Between your hand and your brain
In both your hand and your brain
Question 2
pts
Why do we need a blood–brain barrier?
To prevent proteins from leaking out of the brain
To prevent high blood pressure from damaging the brain
To enable more nutrition to reach the brain
To protect the brain from viruses and harmful chemicals
Question 3
pts
Why is so little research done on local neurons?
Local neurons are tiny.
Local neurons are uncommon.
Local neurons do not convey information.
Local neurons are immature.
Question 4
pts
How does an evolutionary explanation of behavior differ from a functional explanation?
An evolutionary explanation predicts how the behavior will change in the future.
An evolutionary explanation relates a behavior to the maturation of the nervous system.
An evolutionary explanation explains why a behavior is advantageous.
, An evolutionary explanation traces a behavior to ancestral species.
IncorrectQuestion 5
pts
If one action potential started at the cell body (orthodromic) and another one started at the tip of the
axon (antidromic), they would stop when they met at the center. Why?
The overstimulation would damage the axon.
Each run into the other one’s refractory period.
The sodium–potassium pump would cause the action potentials to cease.
Each would fail to find the usual synaptic ending.
Question 6
pts
What is the opposite of dualism?
Vegetarianism
Pacifism
Monism
Solipsism
Question 7
pts
What is a disadvantage of the blood–brain barrier?
It produces electrical discharges.
It forces the body to maintain high blood pressure.
It keeps most nutrients out of the brain.
It puts a limit on brain size.
Question 8
pts
What does depolarization of a neuron membrane mean?
Increasing its negative charge
Decreasing its negative charge
