The Undershoot Phase of After Hyperpolarization Is Due to
These inactivated sodium channels cannot open even if. B sustained opening of voltage-gated potassium channels. Afterhyperpolarization Wikiwand The falling phase is a rapid repolarization followed by the undershoot when the membrane potential hyperpolarizes past rest. . More negative the normal resting potential of -70 mV ie up to -90 mV. This phase also known as undershoot phase. We studied the mecha-. Answer outflow of the potassium ions Explanation - During after hyperpolarisation phase the resting membrane potential goes more negative. The positive currents flowing inward and outward become almost equal during this stage. D slow restorative actions of the sodium-potassium ATPase. The rising phase is a rapid depolarization followed by the overshoot when the membrane potential becomes positive. Afterhyperpolarization or AHP describes the hyperpolarizing phase of a neurons action potential where the cells...
