The Neuron and Neurotransmission

Imagine Maya, Evelyn, and Benjamin are neurons in the brain. The junction between the axon tip of the sending neuron (Maya) and the dendrite or cell body of the receiving neuron (Evelyn or Benjamin) is called?

• axon

• synapse

• dendrite

• vesicle

Imagine Charlotte, Aria, and Oliver are scientists studying the human nervous system. They come across a layer of fatty tissue that insulates the axon and speeds their impulse. What do they call this layer?

• myelin sheath

• threshold

• dendrite

• axon

Imagine you're a tiny human, the size of a molecule, and you've been miniaturized into a neuron. You're in a part of the neuron where you can see the nucleus and the cell's life support system. You're in the control center! What is this part of the neuron called, where you're standing right now? Is it the same place where Henry, Aria, and Benjamin are standing?

• glial cell

• dendrite

• axon

• soma

Imagine Kai, James, and Olivia are tiny scientists exploring the inside of a neuron. They come across an extension that passes messages through its branches to other neurons or to muscles or glands. What is this extension called?

• action potential

• axon

• glial cell

• dendrite

Imagine Nora, Elijah, and Luna are tiny astronauts exploring the vast universe of a neuron. They come across a bushy, branching extension that receives and integrates messages, conducting impulses toward the cell body. What do they call this extension?

• dendrite

• axon

• vesicle

• synapse

Imagine Avery, Benjamin, and Grace are in a science lab studying neurons. They come across a term that describes a neurotransmitter's reabsorption by the sending neuron. What is this term?

• all-or-none response

• synapse

• action potential

• reuptake

Imagine Nora, James, and Ethan are neurons. They have a unique way of communicating. They either send a full-length message or don't send anything at all. What is this phenomenon called in neuroscience?

• all-or-none response

• refractory period

• threshold

• action potential

Ethan, Avery, and Mason are having a debate about neuroscience. They're discussing a neural impulse; a brief electrical charge that travels down an axon. Can you help them identify what this is called?

• neurotransmitter

• action potential

• all-or-none response

• threshold

Imagine Michael, Priya, and Anika are studying neural processing. They come across a concept of a brief resting pause that occurs after a neuron has fired. What is this called?

• threshold

• synaptic cleft

• action potential

• refractory period

Imagine Aiden, Zoe, and Nora are playing a trivia game. Aiden pulls a card and reads, 'This neurotransmitter is linked to feelings of pleasure, euphoria, and reward.' What is he talking about?

• dopamine

• serotonin

• substance p

• glutamate

• endorphins
