Q. Regarding the resting membrane potential in peripheral nerves: (Solved)
1. membrane permeability of potassium ions via K+ leak channels produces the resting potential
2. a decrease in extracellular Ca2+ decreases excitability
3. decreasing external Na+ concentration lowers the resting membrane potential
4. changing the external Na+ concentration has no effect on the action potential
5. decreasing the external K+ concentration increases the resting membrane potential
- a. membrane permeability of potassium ions via K+ leak channels produces the resting potential
