B) -55 millivolts.
C) +40 millivolts.
D) +70 millivolts.

Action Potential

A rapid increase and decrease in the voltage across a cellular membrane due to the movement of ions, allowing neurons to transmit signals.

Electrical Charge

A fundamental property of matter that causes it to experience a force when placed in an electromagnetic field, categorized into positive and negative types.

Millivolts

A unit of electric potential and electromotive force equal to one thousandth of a volt, commonly used in various electrical and physiological measurements.
