WebbThe three distinct phases of a nodal cell action potential; the pre-potential (yellow), de-polarization (red), and re-polarization (blue). As shown in figure 1 , the pre-potential (yellow phase) occurs due to a slow influx of sodium ions until the threshold is reached, followed by a rapid depolarization (red phase) and re-polarization (blue phase) of the cell.
WebbInclude all ion channels (8), ion movements (8) and potential changes (8) that take place during the various phases of the action potential.
