WebImage transcription text. Formation of an Action Potential When a neuron is at _1_ (-70 mV), all the ion channels on the plasma membrane are closed, sodium ions highly concentrated on the _2_ and potassium ions on the _3_ of the cell membrane. At this time, the outside of the cell is positively charged while the inside is negatively charged. WebResting membrane potential of a neuron is about -70mV which means that the inside of the neuron is 70mV less than the outside. There are more k and less NA+ inside and more NA+ and less K+ outside. It is because …
