Node of Ranvier
Myelin Sheath
Drugs such as Oxycodone and Heroine block production or release of some neurotransmitters. These are examples of what?
Antagonists
Agonists
What happens to the neurotransmitters after they are released into the synapse?
They remain attached to the receptor site until another action potential happens.
They are broken down by enzymes or are reabsorbed by the terminal buds.
They are absorbed into the bloodstream
They continue to flow through the next neuron.
The receptor on the 'receiving neuron' is located on this neuron structure.
Cell Body
Axon
Dendrite
Neuron
What process is being observed on the right side of this image?
Diffusion
Reuptake
How does an inhibitory neurotransmitter work
It works by making the neuron more negative and thereby more likely to have an action potential
It works by making the neuron more positive and thereby more likely to have an action potential
It works by making the neuron more negative and thereby less likely to have an action potential
It works by making the neuron more positive and thereby less likely to have an action potential
Why is a neuron's "Threshold" important to neurotransmission?
Threshold is the electrical charge inside the neuron that must be reached in order for an action potential to occur
Threshold is the electrical charge of a neuron that has been depolarized
Threshold is the point at which sodium channels open and allow sodium ion to enter the neuron, allowing for neurotransmission to occur
Threshold is the point at which potassium channels open and allow potassium ion to enter the neuron, allowing for neurotransmission to occur
If you have a disease that increases the amount of sodium ions inside a neuron, what are the resulting "downstream" effects at the Axon Terminal? (hint: the number of open voltage-gated calcium channels depends upon the amount of membrane depolarization)
less synaptic vesicles will be released and more action potentials will be created on the secondary neuron
more synaptic vesicles will be released and more action potentials will be created on the secondary neuron
more synaptic vesicles will be released and less action potentials will be created on the secondary neuron
less synaptic vesicles will be released and less action potentials will be created on the secondary neuron
A condition in which the inside of the cell membrane is more positively charged than the outside.
Resting Potential
Depolarized
Polarized
Repolarized
The rapid skipping of an action potential from node to node on myelinated neurons.
Saltatory conduction
Myelinated Conduction
Neurotransmission
Skipping Conduction

small, dime-sized section of epithelium on the superior surface of your oral cavity that is responsible for the sense of smell.
small, dime-sized section of epithelium on the superior surface of your nasal cavities that is responsible for the sense of smell.
What is neural adaptation?
Sensory adaptation refers to an increase in sensitivity to a stimulus after constant exposure to it
Sensory adaptation refers to the "learning process" your senses goes through; where your brain "stores" senses into your memory so you don't have to learn new senses again and can focus your attention on new sensations.
Sensory adaptation refers to a reduction in sensitivity to a stimulus after constant exposure to it
Sensory adaptation refers to the "un-learning process" your senses goes through; where your brain "removes" senses from your memory in attempt to make room for any new sensations that you experience.
