Why does ether prevents action potential from occuring?

Ether prevents the action potential, by opening potassium ion pores which allow the escape of potassium from the neurons, which results in hyper-polarized of the neuron, thus preventing the action potential from occurring. Ether is an organic functional group consisting of a disubstituted oxygen, or an oxygen atom bonded to 2 carbon atoms. Lock anesthetics block nerve conduction by preventing the increase in membrane permeability to sodium ions that normally leads to a nerve impulse.
