How and why does the action potential of a myocardial cell differ from that of a skeletal muscle cell?
What will be an ideal response?
Answer: The depolarization phase of the myocardial cell is very prolonged compared to the skeletal muscle cell, as a voltage-gated L-type calcium channel opens for a relatively long duration in the cardiac cell. This causes the heart muscle cell to contract more slowly and smoothly than the skeletal muscle cell.
