What is the normal resting potential of the inner side of a nerve cell relative to the outer side?
A. 100 mV.
B. 50 mV.
C. 10 mV.
D. "-50 mV."
E. "-100 mV."
The normal resting potential of -50 MC is established by the sodium-potassium pump of the cell. This results in a high extracellular sodium concentration (~142 mEq / liter) and a high intracellular potassium concentration (A~141 mE~/liter).
