Most Neurons Have a Resting Membrane Potential Of

Question

Most neurons have a resting membrane potential of
A) +100 mV.
B) -55 mV.
C) +30 mV.
D) -70 mV.
E) -5 mV.

Accepted Answer

The resting membrane potential of most neurons is approximately -70 mV. This electrical potential difference across the neuron's membrane is due to the distribution of ions (such as sodium and potassium) and the activity of ion pumps that maintain this gradient.
