Lesson 2.2: The Neuron

• How do neurons communicate with each other?

Multiple Choice

What is a neurotransmitter?

• fatty covering of the axon

• nerve cell

• chemical messenger

• gap between neurons

Multiple Choice

Where are neurotransmitters located within in neuron?

• axon terminals

• dendrites

• Schwann cells

• cell body

Multiple Choice

Neurotransmitters are released from the....

• Dendrites

• Post-synaptic neuron

• Presynaptic neuron

• Axon

Multiple Choice

The tiny gap between neurons where nerve impulses are sent from one neuron to another.

• synapse

• axon terminal

• impulse

• myelin

Multiple Choice

What is being identified with the arrows?

• transporters

• neurotransmitters

• receptor sites

• vesicles

Multiple Choice

After the neurotransmitter crosses he synaptic gap what process occurs?

• Reuptake

• The axon sends the message across the synaptic gap

• The resting period

• Threshold

Multiple Choice

Nicotine can artificially stimulate receptor sites, making it an __________

• Acetylcholine

• Antagonist

• Agonist

• Axon

Multiple Choice

This neurotransmitter is most often associated with pleasure/reward sensations:

• Acetylcholine

• GABA

• Dopamine

• Serotonin

Multiple Choice

The release of this neurotransmitter is 100x more potent than any opiate (painkilling drug):

• Norepinephrine

• Serotonin

• GABA

• Endorphins

Multiple Choice

Serotonin is a neurotransmitter that helps regulate:

• learning and memory

• pain and pleasure

• muscle movements

• sleep, moods/emotions

Multiple Choice

Which neurotransmitter inhibits brain activity?

• Acetylcholine

• GABA

• Endorphins

• Dopamine

Multiple Choice

Which neurotransmitter is released in response to stress and trauma?

• Acetylcholine

• Endorphins

• Serotonin

• GABA
