action potential resistance

Action potential resistance refers to the way nerve cell membranes oppose the flow of electrical signals. When a nerve cell is stimulated, ions (charged particles) move across the membrane, changing its electrical charge. Resistance is like the membrane's obstacle to this ion movement—higher resistance makes it harder for ions to pass through, slowing down the signal, while lower resistance allows ions to flow more easily, speeding up signal transfer. This resistance is essential in regulating nerve signal speed and strength, ensuring precise communication within the nervous system.
