WebThe first phase of the action potential is the rising phase called ‘depolarization’, which occurs due to a stimulus and causes the opening of voltage-gated sodium channels. The … 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.

Nearly all cell membranes in animals, plants and fungi maintain a voltage difference between the exterior and interior of the cell, called the membrane potential. A typical voltage across an animal cell membrane is −70 mV. This means that the interior of the cell has a negative voltage relative to the exterior. In most types of cells, the membrane potential usually stays fairly constant. S… WebNov 2024 - Present1 year 6 months. Detroit, Michigan, United States.
