The potential difference across the membrane of a relaxed muscle fibre is called resting potential. It amounts to about

Conduction of an impulse along the axon is associated with the

The resting potential of the membrane is

An action potential in a nerve fiber is generated when the outer surface is positive and the inner surface is negative,and the membrane potential is reversed because...

$A$: In the nervous system,the generation of an action potential depends upon the influx of sodium ions into the axoplasm.
$R$: The influx of sodium ions during nerve impulse generation is due to the efflux of potassium ions.

During the conduction of a nerve impulse along a neuron,what is the nature of the electrical charge on the inner side of the plasma membrane?
