Quizplus · Accepted Answer

The correct sequence for the transmission of the action potential through the cardiac conduction system starts with the sinoatrial (SA) node, then moves to the atrioventricular (AV) node, followed by the AV bundle (bundle of His), then to the right and left bundle branches, followed by the Purkinje fibers, and finally to the contractile cells of cardiac muscle tissue.
