How do pacemaker cells differ from cardiac myocytes? Where are the 3 locations of pacemaker cells?
What does it mean to say that cardiac muscle functions as a syncytium?
What happens to generate pacemaker potentials in pacemaker cells? What events happen with the generation of the pacemaker action potential? Be clear on the ions involved and the directionality of their flow into or outside of the cell.
What is the path of pacemaker action potentials as they spread from the AV node to the ventricular myocardiocytes?
What is involved with the depolarization, plateau, and repolarization phases of the myocardial action potential? Be clear on the ions involved and the directionality of their flow into or outside of the cell. Which aspect of ion movement results in myocyte contraction resulting in myocyte contraction?
