網頁2024年4月8日 · An action potential begins at the axon hillock as a result of depolarisation. During depolarisation, voltage-gated sodium ion channels open due to an electrical stimulus. As the sodium ions rush back into the cell, their positive charge changes potential inside the cell from negative to more positive. http://pressbooks-dev.oer.hawaii.edu/anatomyandphysiology/chapter/the-action-potential/
