Question

1. Cardiac pacemaker cells are extremely important for normal regulation of heart rhythm. These autorhythmic cells undergo spontaneous action potentials caused by pacemaker potentials. How do these cells spontaneously depolarize (i.e., what happens?). How do they generate an action potential? Diagram and explain their action potentials and label each portion of the wave and what causes each deflection. Describe how an action potential is generated in contractile cells and how it is coupled with contraction. Draw what the action potential looks like, label the deflections of the wave and indicate what is causing each deflection.
