When extracellular K+ is normal the nerve repolarises normally and returns to its original resting potential
When extracellular K+ is slightly elevated, more K+ will leave the nerve cell when it is repolarizing and as a result the cell will stabilize at resting potential that is higher than normal this resting potential is closer to threshold. Since a cell fires when its potential reaches more, this cell will fire lower easily. The patient will experience cramps and tingling.
The potassium outflow hyperpolarizes the neuron by a normal process, in which the movement of positively charged K+ ions to the outside of the cell moves the interior-anchored voltage potential in the negative direction.
