Introductory Level (high school or lower-level undergraduate students) |
Moderate Level (third- or fourth-year undergraduate students) |
Advanced Level (upper-level undergraduate or graduate students) |
What membrane changes can help an action potential move down the axon? | Would an increase or decrease in membrane resistance allow an action potential to propagate faster? | How does membrane resistance impact action potential conduction velocity? |
How can a neuron increase its membrane resistance? | What does myelin do to a neuron’s membrane resistance? | How does myelin affect resistance and capacitance and what does that do to action potential propagation? |
How does axon diameter impact action potential propagation? | Would an increase or decrease in axon diameter speed up an action potential? | How do myelinated axons speed up an action potential more than larger diameter axons? |
What enters the cell at the Node of Ravnier? | What type of ion channels are located at the Node of Ranvier? | What factors influence the movement of sodium ions at the Nodes of Ranvier? |
If sodium ions enter the cell, what happens to the voltage? | During summation, which ions would lead to an increase amplitude of the signal? | How can the reversal potential for sodium influence movement into the cell to summate and increase the voltage? |
