網頁Cardiac action potentials differ from the APs found in other areas of the body. Typical neural AP duration is around 1ms and those of skeletal muscle are roughly 2-5ms, whereas cardiac action potentials range from 200-400ms.

網頁Terms in this set (4) Step 1 - Resting Potential. Sodium and potassium channels are closed. Na+ rush into the cell; K+ are concentrated inside the cell. Step 2 - Depolarization. … 網頁Action potentials are considered an “all-or nothing” event, in that, once the threshold potential is reached, the neuron always completely depolarizes. Once depolarization is complete, the cell must now “reset” its membrane voltage back to the resting potential. To accomplish this, the Na + channels close and cannot be opened.
