The plateau of the cardiac action potential results from the opening of voltage-gated slow ______ channels in the plasma membrane of the cardiac cell.

Question

Quizplus · Accepted Answer

The plateau of the cardiac action potential is a result of the opening of voltage-gated slow calcium channels in the plasma membrane of the cardiac cell. This allows for a sustained influx of calcium ions that helps maintain the contraction of the cardiac muscle cells. Sodium channels are responsible for the rapid depolarization phase of the action potential, while potassium channels are responsible for repolarization. Chloride channels are not involved in the cardiac action potential.
