What is the resting membrane potential range for neurons?

The resting membrane potential for neurons generally falls within the range of -60 to -70 mV. This potential is primarily established by the distribution of ions across the neuronal membrane, particularly sodium (Na+) and potassium (K+) ions, along with the permeability of the membrane to these ions.

In most neurons, the resting membrane potential is closer to -70 mV. This value indicates that the inside of the neuron is negatively charged relative to the outside, resulting from a higher concentration of K+ ions inside the cell compared to the outside and the activity of sodium-potassium pumps that maintain these ion gradients. This resting potential is critical for the function of neurons, allowing them to generate action potentials in response to stimuli.

The range provided as the correct answer (B) adequately reflects the general consensus on the typical resting membrane potential for neurons, establishing the basis for their excitability and response to synaptic signals.
