3 Questions
What happens to the membrane potential when the net current of Na+ ions inflowing and K+ ions outflowing have the same magnitude?
The membrane potential remains unchanged
If there is a net outflow of K+ ions, what effect does it have on the membrane potential?
Makes the membrane potential more negative
What is the effect of a net inflow of Na+ ions on the membrane potential?
Makes the membrane potential more positive
Test your knowledge of neuronal membrane potential changes with this quiz. Learn about the effects of net inflow and outflow of Na+ and K+ ions on membrane voltage, and understand the impact of equal magnitude currents on membrane potential.
