Neurons
100

Neurotransmitters are chemicals that transmit signals between these cells.

What are neurons?

100

This neurotransmitter helps regulate mood, appetite, and sleep.

What is serotonin?

100

Low levels of serotonin are commonly linked with this mental health disorder.

What is depression?

100

This type of drug increases neurotransmitter activity.

What is an agonist?

100

The part of the neuron that carries the action potential away from the cell body

What is the axon?

200

This small gap between neurons is where neurotransmitters travel.

What is the synaptic cleft (or synapse)?

200

These “feel-good” neurotransmitters act as natural painkillers.

What are endorphins?

200

Excess dopamine activity is associated with this serious mental disorder.

What is schizophrenia?

200

This type of drug decreases or blocks neurotransmitter activity.

What is an antagonist?

200

This part of the neuron receives and integrates messages

What are the dendrites?

300

This neurotransmitter is most associated with pleasure, reward, and motivation.

What is dopamine?

300

This neurotransmitter prepares the body for fight-or-flight responses.

What is norepinephrin?

300

A lack of acetylcholine is linked to this neurodegenerative disorder that affects memory.

What is Alzheimer’s disease?

300

SSRIs (selective serotonin reuptake inhibitors) increase levels of this neurotransmitter.

What is serotonin?

300

The junction in which neurotransmitters are sent between neurons

What is the synapse?

400

This neurotransmitter enables muscle movement and is linked to learning and memory.

What is acetylcholine (ACh)?

400

The neurotransmitter that is an excitatory, involved in memory, and can be found in some food

What is Glutamate?

400

Low levels of GABA are linked to these conditions

What are seizures, tremors, and insomnia?

400

Drugs like heroin or morphine mimic this type of neurotransmitter.

What are endorphins?

400

The phase in which a neuron is firing

What is depolarization?

500

This neurotransmitter is the brain’s main inhibitory neurotransmitter.

What is GABA (gamma-aminobutyric acid)?

500

This neurotransmitter is associated with our reward pathway, and is released when we use things like TikTok

What is dopamine?

500

Overactivation of glutamate can lead to these conditions

What are migraines and seizures?

500

Nicotine acts as an agonist for this neurotransmitter that controls muscle movement.

What is acetylcholine?

500

This happens to neurotransmitters when there are not enough receptor sites for all of them

What is reuptake?
