A nerve impulse is the relaying of a coded signal from a nerve cell to an effector (a muscle cell, a gland cellor another nerve cellin response to a stimulus. It is the means by which a nerve cell communicates with another cell. This signal is relayed along the axon of the nerve cell, bringing a message that instructs an effector to act.
