Parts of a Neuron
This part of the neuron sends the action potential away from the cell body and toward the synapse.
What is the axon?
The action potential travels from the neuron's ________ to the neuron's __________.
What is "dendrites to axon terminal?"
The formal vocabulary terms for "the neuron that is sending the signal across the synapse" and "the neuron that is receiving the signal."
What is presynaptic and postsynaptic?
This part of the brain provides emotional coloring to memories, and specializes in fear.
What is the amygdala?
This part of the brain connects the two hemispheres.
What is the corpus callosum?
Receptors for neurotransmitters are located on a neuron's _________.
What are dendrites?
This is how a neuron resets itself for the next action potential.
What is "pump the positive charges back out of the cell?"
These molecules are contained in vesicles while the neuron is at rest.
What are neurotransmitters?
This part of the brain is in charge of keeping things like hunger, temperature, and sleep in balance.
What is the hypothalamus?
This neurotransmitter can be considered your "pay attention to this!" chemical.
What is dopamine?
This part of the neuron contains the nucleus.
What is the cell body?
When an action potential is triggered, ________ ions enter the neuron through the now-open channels.
What is sodium?
After the neurotransmitters have crossed the synapse and bound to their receptors, thus transmitting the signal, what happens to them?
What is reuptake by the first neuron?
This part of the brain put short-term memories into long-term storage.
What is the hippocampus?
How can you coax a neuron to create a stronger action potential?
What is "you can't"?
This end of the neuron is the one that receives signals from the previous neuron in line.
What is the dendrites?
When there is no difference in electrical charge between the outside and the inside of the neuron, we say the neuron is _____________.
What is depolarized?
If this neurotransmitter binds to its receptors on a neuron, it will make it harder for that neuron to start an action potential.
What is GABA?
This part of the brain sends voluntary movement signals to muscles.
What is the motor cortex?
These neurotransmitters are also known as "the brain's natural opiates" and are responsible for mild pain relief and the "runner's high."
What are endorphins?
The channels along a neuron's axon will only open up when they sense this change inside the cell.
What is increased positive charge?
When the membrane potential has reached the level needed to kick off an action potential (typically around -55 mV), we say the membrane has reached the __________ potential.
What is the threshold potential?
An excitatory neurotransmitter makes it ________ for the neuron to start an action potential.
What is easier?
This part of the brain serves as a relay station, deciding what information needs to go to what parts of the brain.
What is the thalamus?
This lobe of the brain integrates sensory information from the visual system, the auditory system, the touch receptors, and the taste receptors.
What is the parietal lobe?
