In a neuron at rest

WebAt rest, there are relatively more sodium ions outside the neuron and more potassium ions inside that neuron. Action Potential The resting potential tells about what happens when a neuron is at rest. An action potential occurs when a neuron sends information down an axon, away from the cell body. WebIn neurons, the resting membrane potential depends mainly on movement of. K through potassium leak channels. In order to maintain a resting membrane potential, there needs …
