12. Ion Concentration and Permeability

13. Equilibrium membrane potential for potassium is -75 to -100mV. EKEK

14. E Na Equilibrium membrane potential for sodium is +40 to +60mV.

15. Action Potential Boundaries EKEK E Na

16. An action potential is a rapid change from a potassium dominated potential to a sodium dominated potential and back.
