Transporter
Which part of a neuron releases neurotransmitters?
Dendrite
Axon terminal
Cell body
Receptor
How do neurotransmitters send messages to the next neuron?
By attaching to receptors on the receiving nerve cell
By creating sparks in the synapse
By dissolving in the bloodstream
By changing the shape of the neuron
What do transporters do in the brain?
They create new neurons
They recycle neurotransmitters
They destroy old neurons
They send signals to muscles
Which analogy best describes how a neurotransmitter and its receptor work?

Like a key and a lock
Like a book and a shelf
Like a pen and paper
How can drugs affect the brain?

Decreasing heart rate
How do drugs like marijuana and heroin affect the brain?
They mimic neurotransmitters and activate nerve cells
They increase muscle strength
They decrease the amount of oxygen in the blood
They improve vision
What is the main effect of drugs like cocaine and methamphetamine on dopamine in the brain?
They cause nerve cells to release too much dopamine or prevent its normal recycling
They decrease dopamine production
They increase the size of nerve cells
