Muscle Physiology 2: Voltage-Gated Potassium Channels and the Action Potential

The video tutorial covers the role of voltage gated sodium and potassium channels in muscle cell action potentials. It explains how sodium influx initiates depolarization, while potassium efflux leads to repolarization. The tutorial also highlights the differences in voltage sensitivity between these channels and introduces the sodium-potassium pump, which restores ion balance after an action potential.
