What are the factors that significantly contribute to the Resting Membrane Potential
(RMP) of excitable tissues. If the extracellular concentration of sodium (Na+) inreased
from 150 mM to 180 mM, would you expect a significant change in RMP? Explain Why
or Why not.

Describe the shape of the action potential and explain the various phases of the action
potential, including the contributions of the various ion channels responsible for its
characteristic shape. How would you expect the shape and magnitude of the action
potential to change if a drug was applied to the axon which blocked 30% of the
potassium channels?
