What major movements of ions account for each phase of the action potential of a typical myocardial cell?

In a cardiac auto-rhythmic cell what is the mechanism involved in the change in membrane potential Depolarization: Pna increases, Peak: Na channels close, Plateau: Calcium channels open & Potassium channels close, Repolarization Potassium flows in & Calcium flows out Depolarization: Pna increases, Peak: Na channels close, Plateau: Calcium channels close & Potassium channels open, Repolarization Potassium flows out & Calcium flows in Pacemaker: K+ and Na+ flow, Depolarization: Pca rises Repolarization: Pk rises, 4. If channels close Pacemaker: K+ and Na+ flow, Depolarization: Pca rises Repolarization: Pk rises Depolarization: P wave Repolarization: QRS Complex, Hyperpolarization: T wave O O

What term is used to describe normal, quite blood flow?

Which of the following channels is responsible for generating the long plateau found in the action potentials of ventricular myocytes?   a-slow Na+ channels b-slow Ca2+ channels c-leaky Ca2+ channels d-leaky Na+ channels
