The events that set up an action potential at one spot on the nerve fibre also transmit it along the entire length of the nerve fibre. The changes in membrane permeability at one site upset the normal membrane permeability at the adjacent area.

WebAction potentials are triggered when enough depolarization accumulates to bring the membrane potential up to threshold. When an action potential is triggered, the membrane potential abruptly shoots upward and then equally abruptly shoots back downward, often ending below the resting level, where it remains for some period of time.
