Detailed explanation-1: -So, when an axon is at rest, the anions give it a negative charge, the sodium pumps keep sodium out and potassium in, and the sodium gates and potassium gates are all closed. Because of the positive-negative difference between the inside and outside, this resting state is called a resting potential.
Detailed explanation-2: -A neuron is at rest when it is not sending an an electrical signal. During this time, the inside of the neuron is negative relative to the outside.
Detailed explanation-3: -The negative charge within the cell is created by the cell membrane being more permeable to potassium ion movement than sodium ion movement. In neurons, potassium ions are maintained at high concentrations within the cell while sodium ions are maintained at high concentrations outside of the cell.
