Mоdule 7 Cоmpаre the аctiоn potentiаls of cardiac conductive cells and cardiac contractile cells. In your response, address the following: What are the key ions involved in each type of action potential, and how do they contribute to depolarization and repolarization? (5 points) Which cell type has a plateau phase, and what causes it? (4 points) How do their resting membrane potentials differ, and which cell type is capable of spontaneous depolarization? (4 points) What is the functional significance of these differences in the context of the cardiac cycle? (7 points)
