Quizplus · Accepted Answer

The atria and ventricles are separated by the fibrous skeleton which is an insulator that blocks the spread of electrical impulses. However, there is a connection between the atria and ventricles called the AV node where depolarization can slowly pass through a slender connection of cardiac muscle cells. The other options are not involved in this inter-atrial and inter-ventricular conduction.
