Neuron Structures
The part of the neuron that houses the nucleus
What is the cell body or soma
The name for a neuron in its natural, non-firing state.
What is resting potential OR polarization?
ACh, GABA, and Dopamine are examples of these.
What are neurotransmitters?
Your bodies natural pain killers.
What are endorphins?
The time period when a neuron cannot fire again because positively charged ion's are still within the axon
What is the absolute refractory period?
What is the Dendrite
This is the name for when positively charged ions enter the axon, creating a neural impulse.
What is action potential OR depolarization?
The terminal buttons of a sending neuron, synaptic gap, and receptor sites of a receiving neuron are the components of this.
What is the synapse?
Too little of this neurotransmitter is associated with Alzheimer's Disease
What is Acetylcholine (ACh)?
Disorder associated with a deteriorated myelin sheath
What is multiple sclerosis?
This part of the neuron has semi-permeable gates that allow positively charged ions to enter the neuron.
What is the axon
This rule says a neuron complete fires, or does not.
What is the All or None Law/Response?
The process excess neurotransmitters go through when there are no receptor sites to bind with.
What is reuptake/re-absorbtion?
This neurotransmitter is your major inhibitory neurotransmitter
What is GABA (Gamma-Aminobutyric Acid)?
These cells create the myelin sheath
This structure houses synaptic vesicles and plays an important role in the chemical communication of neurons
What is/are the terminal button(s)
After being hit on the back, this is the reason why you wouldn't feel a light tap in the same spot.
What is the relative refractory period?
Morphine is an example of this kind of drug.
What is an agonist?
This is a major excitatory neurotransmitter, and sometimes a derivative of this is used as a food additive.
What is glutamate?
White brain matter mostly consists of this part of the neuron
What are myelinated axons?
These types of neurons, also called motor neurons, are responsible for carrying information from the brain to the rest of the body
What are Efferent Neurons?
The explanation for why you may not notice a spider crawling on your leg until it is halfway up.
What is subthreshold depolarizations added together through summation?
These two drugs specifically target serotonin and norepinephrine to continue neural communication.
What are SSRI's and SNIR's
This is approximately how many neurotransmitters are within on synaptic vesicle
What is 10,000?
These types of neurons, also known as sensory neurons, carry information toward the brain.
What are Afferent neurons?
