WitrynaThe transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized—that is, there is a difference in electrical charge between the outside and inside of the membrane.

Witryna12 mar 2024 · The cardiac electrical signal controls the heartbeat in two ways.
