Differences between nodal cells and atrioventricular myocytes.
Why is an AV node cell action potential slower than an atrial or ventricular myocyte?© SolutionLibrary Inc. solutionlibary.com 9836dcf9d7 https://solutionlibrary.com/biology/human-biology/differences-between-nodal-cells-and-atrioventricular-myocytes-1pf
...troke and greater amplitude of the action potential. This is due to the rapid influx of sodium ions through fast sodium channels. The rapid influx allows a more rapid change in membrane potentials of adjacent cells and therefore a more rapid propagation and spread of potential to a greater distance. AV nodal cells have an upstroke that is achieved by the relatively slow influx of calcium ions and an action potential ...
