Explain the significance of the plateau period during the action potential of a cardiac contractile cell
What will be an ideal response?
The plateau period of contractile cell action potential slows the heart rate, allows the heart to fill with blood, increases the strength of the heart's contraction, and prevents tetany by lengthening the heart's refractory period. The prevention of tetany allows the heart to relax and the ventricles to refill with blood before the cardiac muscle cells are stimulated to contract again.
