Verified
The membrane potential of a neuron at rest, or what is termed its "resting potential," is about __________
A) -50 millivolts.
B) -70 millivolts.
C) +50 millivolts.
D) +70 millvolts.
Resting Potential
The difference in voltage across the neuronal membrane when the neuron is not actively sending a signal, typically around -70mV.
Membrane Potential
The electrical potential difference across a cell's plasma membrane, crucial for the transmission of nerve impulses and muscle contraction.
Millivolts
A unit of electric potential equal to one thousandth of a volt, commonly used in various fields such as physics and electrophysiology to measure small voltage differences.

Final Answer :
B
Explanation :
The resting potential of a neuron is typically around -70 millivolts. This means that the inside of the neuron is more negative compared to the outside.
