Information is transmitted both quickly and accurately by electrical means through
Nerve impulse
Nerve impulses are transmitted through the change in the concentration of sodium ions on the surface of the nerve cell which happens upon receiving a stimulus by receptors and then by the dendrites of neurons.
Stimulus is an agent or a sudden change of the external or internal environment that results in a change in an organism or any of its body parts.
A response is a change in an organism resulting due to stimulus.
