MEDICAL PHYSIOLOGY

Detailed explanation-1: -The negative resting membrane potential is created and maintained by increasing the concentration of cations outside the cell (in the extracellular fluid) relative to inside the cell (in the cytoplasm).

Detailed explanation-2: -Your answer: The resting membrane potential will become less negative.

Detailed explanation-3: -If the membrane potential becomes more positive than it is at the resting potential, the membrane is said to be depolarized. If the membrane potential becomes more negative than it is at the resting potential, the membrane is said to be hyperpolarized.

Detailed explanation-4: -The key point is that the increase in Na+ permeability would produce a greater depolarization, which will lead to an even greater number of Na+ channels opening and the membrane potential becoming even more depolarized.
