The phases of the action potential include
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. WebbWhen a neuron is not at rest, the neuron is transmitting an action potential. An action potential can be further broken down into its separate stages: depolarization, …

WebbThe beginning of the action potential is represented in Figure 1 as phase 1. At this point, the cell is at rest and the membrane potential is approximately -70 mV.During phase 2, … The cardiac action potential differs from the neuronal action potential by having an extended plateau, in which the membrane is held at a high voltage for a few hundred milliseconds prior to being repolarized by the potassium current as usual. This plateau is due to the action of slower calcium channels opening and holding the membrane voltage near their equilibrium potential even after the s…
