Start studying membrane potentials learn vocabulary, terms, and more with flashcards, games, and other study tools. An action potential is a brief (only a few milliseconds) reversal of the membrane potential (v m) at rest, the v m of a neuron is around −70 mv (closer to the equilibrium potential for potassium, v k ), but during an action potential, v m transiently approaches +50 mv (closer to the equilibrium potential for sodium, v na ). Action potentials generated by neural impulses are “all or nothing,” meaning the signal reaches the threshold for communication or it doesn’t no signal is stronger or weaker than another depolarization increase in positive charge inside the plasma membrane caused by a depolarizing graded potential causes increasing numbers of voltage .
