four properties of cardiac cells - CORRECT ANS enable the conduction system to start an electrical impulse, send it through the cardiac tissue, and stimulate muscle contraction -automaticity -excitability -conductivity -contractility automaticity - CORRECT ANS •is the ability to initiate an impulse spontaneously and continuously. excitability - CORRECT ANS •is the ability to be electrically stimulated. Conductivity - CORRECT ANS •is the ability to transmit an impulse along a membrane in an orderly manner. contractility - CORRECT ANS •is the ability to respond mechanically to an impulse. normal cardiac impulse - CORRECT ANS begins in the sinoatrial (SA) node in the upper right atrium. It spreads over the atrial myocardium via interatrial pathways and internodal pathways, causing atrial contraction. The impulse then travels to the atrioventricular (AV) node, through the bundle of His, and down the left and right bundle branches. It ends in the Purkinje fibers, which transmit the impulse to the ventricles
