The Membrane Potential, Voltage-Gated Ion Channels and Action Potentials
This is the first tutorial in a series on Action Potentials. This video looks at how the Na+/K+ ATPase Ion Transporter sets up a voltage across a membrane.
This second tutorial looks at how the Voltage Gated Na+ & K+ Ion channels change the voltage across the membrane of a cell and thus produce an action potential.
This is the third tutorial in a series on Action Potentials. This video looks at how the an action potential propagates across a membrane, such as that of an axon.
