A nerve impulse is the relaying of a coded signal from a nerve cell to an effector (a muscle cell, a gland cell or another nerve cell) in response to a stimulus.
-also known as a nerve impulse is when the membrane potential conducts an impulse. ( not at rest anymore, something trigger electrical impulse on membrane) -When an adequate amount of stimulus excites the membrane, stimulus-gated sodium (Na+) channels open, allowing Na+ to diffuse into the cell at a very fast rate.
