Gated sodium channels
WebVoltage-gated sodium channels (VGSCs) are present in many tissue types within the human body including both cardiac and neuronal tissues. Like other channels, VGSCs activate, deactivate, and inactivate in response to changes in membrane potential. VGSCs also have a similar structure to other channel …. WebVoltage-gated sodium channels open once the cell’s membrane potential reaches threshold. The rapid influx of sodium results in a large depolarization called the rising …
