Neurotransmission Review

What part of the neuron receives the chemical message?

• dendrite

• axon

• soma

• terminal branches

• myelin sheath

If the message sends, the message will travel down the neuron's _.

• dendrite

• axon

• soma

• terminal branches

• synapse

This part of the neuron covers the axon in order to accelerate the speed of the message.

• dendrite

• axon

• soma

• terminal branches

• myelin sheath

Once the message reaches the _, it stimulates the release of neurotransmitters for the whole process to happen again at the next neuron.

• dendrite

• axon

• soma

• terminal branches

• myelin sheath

If the neurotransmitters stimulate the neuron to its, threshold the message will send. What is the threshold?

• -70mV

• -55mV

• +35mV

When a neuron is ready to take on a message, it is considered to be in _.

• resting potential

• action potential

• refractory period

When a neuron is actively sending a message, it is considered to be in _.

• resting potential

• action potential

• refractory period

When a neuron is recharging and cannot fire, it is in what stage?

• resting potential

• action potential

• refractory period

When a neuron is in resting potential, its charge is considered to be:

• polarized.

• depolarized.

• repolarized.

During action potential, the charge is:
