Describe in detail the action potential of myocardial
contractile cells. Be sure to names the phases, include the main
types of membrane proteins involved, how they are opened, the
movements of ions, and the changes in membrane potential. Explain
how this type of action potential is different from that seen in a
skeletal muscle cell and why the difference(s) are significant.
