GENERAL HISTOLOGY

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 Definition In the resting state, there is no signal passing through the neuron. However, even in this state, the neuron is electrically active. Because of how ions are moving across the cell membrane, the inside of the neuron is more negative than the fluid that surrounds it.

Detailed explanation-3: -When the depolarization reaches about-55 mV a neuron will fire an action potential. This is the threshold. If the neuron does not reach this critical threshold level, then no action potential will fire.
