Which system is responsible for preparing a hiker to act quickly when she sees a bear run onto the path in front of her?

Efferent neurons

Central nervous system

Sympathetic nervous system

Parasympathetic nervous system

Under what conditions does an axon produce an action potential?

Whenever the membrane is hyperpolarized

Whenever the membrane is depolarized

Whenever the membrane’s potential reaches the threshold

Whenever the membrane’s potential reaches zero

If a membrane is depolarized to twice its threshold, what happens?

The neuron produces the same action potential it would at the threshold.

The neuron produces an action potential that travels twice as fast as usual.

The neuron produces an action potential slightly stronger and slightly faster than usual.

The neuron produces an action potential at twice as much strength as usual.

What is most distinctive about neurons, compared to other cells?

Their temperature

Their shape

Their color

Their internal components, such as ribosomes and mitochondria

Which of the following is a function of microglia?

Microglia build myelin sheaths that surround and insulate axons

Microglia remove dead cells, viruses, and weak synapses

Microglia synchronize activity for a group of neurons.

Microglia dilate blood vessels to increase blood supply to active brain areas.

When a neuron is hyperpolarized, it __________.

Cannot respond to new stimuli

Becomes more sensitive to new stimuli

Responds as normal and is not affected at all

None of the above

Once a gated channel is open, positive ions will enter through the channels to get inside the neuron. Which of the following can cause the gated channels to open?

Stimulus

Impulse

Action potential

Neurons

Once a gated channel is open, positive ions will enter through the channels to get inside the neuron. Which of the following can cause the gated channels to open?

Impulse

Stimulus

Resting potential

Trigger

Which of the following would be the best and most accurate way of describing an action potential?

If there are enough stimuli, the sodium ion channels (gates) will open only in the dendrite area. There have to be additional stimuli to get the channels to open in the axon area.

If there are enough stimuli, the sodium ion changes (gates) will open in succession all the way down an axon.

If there are enough stimuli, the sodium ion channels (gates) will open all at the same time within the axon.

If there are enough stimuli, the potassium ion changes (gates) will open in succession all way down the axon

Which of the following statements is FALSE?

If the stimulus reaches the threshold level, depolarization will occur.

If the stimulus does not reach the threshold level, depolarization will not occur.

If the stimulus almost reaches the threshold level, depolarization will only occur half way down the axon.

What is the most common inhibitory neurotransmitter in the brain?

Dopamine

Gamma-aminobutyric acid(GABA)

Glycine

Glutamate

Excitation

Has no effect on the neighbouring neuron

Makes it less likely the neighbouring neuron will fire

Bypasses the neighbouring neuron

Makes it more likely the neighbouring neuron will fire
