By an action potential, abbreviated AP, we mean a generalized [[cell membrane|membrane]]-[[depolarization]] of a [[cell]] when the [[membrane potential]] reaches a threshold value due to changes in the [[ion]] fluxes by extracellular chemical or physical signals or by intracellular metabolic processes. At the heart, the AP appears at the pacemaker cells, the [[Purkinje fibers]] and the work[[myocardium]], where it initiates the [[contraction]]. The AP of the heart muscle cells differs from the AP of the [[nerve cells]] by a pronounced plateau as a result of a strong [[calcium]] influx that begins with depolarization.

Nachricht im Original (Aktionspotential)
Unter einem Aktionspotential, abgekürzt AP, verstehen wir eine generalisierte [[Zellmembran|Membran]]-[[Depolarisation]] einer [[Zelle]], wenn das [[Membranpotential]] infolge Änderung der [[Ionen]]flüsse durch extrazelluläre chemische oder physikalische Signale oder durch intrazelluläre Stoffwechselprozesse einen Schwellenwert erreicht. Am Herzen tritt das AP an den Schrittmacher-Zellen, den [[Purkinje-Fasern]] und dem Arbeits[[myokard]] in Erscheinung, wo es die [[Kontraktion]] einleitet. Das AP der Herzmuskelzellen unterscheidet sich vom AP der [[Nervenzellen]] durch ein ausgeprägtes Plateau infolge eines mit der Depolarisation einsetzenden starken [[Kalzium]]-Einstroms.
ÜbersetzungAn action potential, abbreviated AP, is a generalized [[Zellmembran/en|membrane]] [[Depolarisation/en|depolarization]] of a [[Zelle/en|cell]]. 

The [[Membranpotential/en|membrane potential]] reaches a threshold value due to changes in the [[Ionen/en|ion]] fluxes by extracellular chemical or physical signals or by intracellular metabolic processes. 

In the heart, the AP appears at the pacemaker cells, the [[Purkinje-Fasern/en|Purkinje fibers]] and the working [[Herzmuskel/en|myocardium]], where it initiates  [[Kontraktion/en|contraction]]. The AP of the heart muscle cells differs from the AP of the [[Nervenzellen/en|nerve cells]] by a pronounced plateau as a result of a strong [[Calcium/en|calcium]] influx that begins with depolarization.

An action potential, abbreviated AP, is a generalized membrane depolarization of a cell.

The membrane potential reaches a threshold value due to changes in the ion fluxes by extracellular chemical or physical signals or by intracellular metabolic processes.

In the heart, the AP appears at the pacemaker cells, the Purkinje fibers and the working myocardium, where it initiates contraction. The AP of the heart muscle cells differs from the AP of the nerve cells by a pronounced plateau as a result of a strong calcium influx that begins with depolarization.
