Witryna5 mar 2024 · Action Potential. A nerve impulse is a sudden reversal of the electrical charge across the membrane of a resting neuron. The reversal of charge is called an action potential. It begins when the neuron receives a chemical signal from another cell. The signal causes gates in sodium ion channels to open, allowing positive sodium … Witryna2 dni temu · Action potentials are nerve signals. Neurons generate and conduct these signals along their processes in order to transmit them to the target tissues.
