<u>Answer:</u>
The typical state of a neuron is the<u> resting potential</u>, but when electrical signals stimulate it to its threshold, the <u>action potential</u> is immediately observed.
<u>Explanation:</u>
The capacity for rest shows what occurs when a neuron is at rest. A capacity for action takes place when a neuron passes information down an axon, far from the cell body. When depolarization exceeds approximately -55 mV a neuron can activate the capacity for action.
Sodium-potassium valves start moving two potassium ions within the cell as three sodium ions are poured out to keep the negatively charged membrane within the cell; this keeps the resting potential in place.
