Voltage gated Na channels

Dr. Morton explains the structure and function of voltage gated sodium channels (VGSC), detailing their anatomy, conformational states, and role in action potentials. VGSCs are transmembrane proteins that open in response to changes in membrane potential, allowing sodium ions to flow in. They have three states: closed, open, and inactive. The video also covers the process of repolarization and the role of VGSCs in neurons and cardiac cells.
