When an axon is not conducting a nerve impulse and there is more sodium outside the axon and more potassium inside the axon it is referred to as:

When a neuron is not conducting an impulse,its resting potential is about F1F1F1S1F1F1F1070 mV;the negative sign indicates that the inside of the axon is more negative than the outside.The existence of this membrane potential can be correlated with a difference in ion distribution on either side of the axon membrane.The unequal distribution of these ions is,in part,due to the activity of the sodium-potassium pump,which moves three sodium ions (Na+)out of the neuron for every two potassium ions (K+)it moves into the neuron.The membrane is more permeable to K+ than to Na+,and therefore more K+ leaks out of the cell than Na+ leaks in.There are also large,negatively charged proteins in the cytoplasm of the axon.See Figure 27.2A.
