Detailed explanation-1: -When a neuron is not actively transmitting a nerve impulse, it is in a resting state, ready to transmit a nerve impulse. During the resting state, the sodium-potassium pump maintains a difference in charge across the cell membrane of the neuron.
Detailed explanation-2: -Resting Potential When a neuron is not conducting a nerve impulse, it is said to be at rest. The resting potential is the resting state of the neuron, during which time the neuron has an overall negative charge. The resting potential in neurons is approximately-70 milliVolts (mV).
Detailed explanation-3: -An action potential is an electrical signal involving nerve cells. A neuron that is not conducting electrical signals is “resting”, usually at about −70 mV, though this varies.
Detailed explanation-4: -Therefore, when a neuron is in resting state, the axonal membrane is comparatively more permeable of K ions and nearly impermeable to Na ions.
