WebAction Potential (AP) a sudden change in the polarity of a neuron caused by a stimulus which results in the inside of the axon membrane reaching -55 millivolts (threshold) and Na+ channels opening causing depolarization. Graded Potential. any stimulus received which was not great enough to have the inside of the axon's membrane reach -55 ... WebAction potentials are considered an “all-or nothing” event, in that, once the threshold potential is reached, the neuron always completely depolarizes. Once depolarization is complete, the cell must now “reset” its membrane voltage back to the resting potential. To accomplish this, the Na + channels close and cannot be opened. pc hi-fiWebAug 8, 2024 · National Center for Biotechnology Information pchifi foobar
