What Is The Electrical Charge Of A Resting Axon Membrane?

What Is The Electrical Charge Of A Resting Axon Membrane? A neuron at rest is negatively charged because the inside of a cell is approximately 70 millivolts more negative than the outside (−70 mV); this number varies by neuron type and by species. What is the electrical potential of an axon? At the axon hillock
