WebMay 15, 2024 · An action potential is a rapid sequence of changes in the voltage across a membrane. The membrane voltage, or potential, is determined at any time by the relative ratio of ions, extracellular to intracellular, and the permeability of each ion. WebIn the pacemaking cells of the heart (e.g., the sinoatrial node ), the pacemaker potential (also called the pacemaker current) is the slow, positive increase in voltage across the cell 's membrane (the membrane potential) that occurs between the end of one action potential and the beginning of the next action potential. outback wild horse toursWebFeb 8, 2024 · This suggests that the RP might be an involuntary component of voluntary action over which people cannot exert conscious control.
