Video Introduction

The content is sourced from: https://youtu.be/TUOSCEVt6HI?si=ycX_FDuN3vO9tmdK

In this video, I cover the basics of the action potential beginning with an explanation of membrane potential and how it sets the stage for the action potential. Then, I describe how an action potential is generated and how it ends. I cover the propagation of an action potential down the axon and the role myelin plays in this process. Finally, I discuss the absolute and relative refractory periods and what they mean for repeated action potential firing. ^[1]^[2]^[3]
