"Physio Flip" contains a semester's worth of physiology lectures, created by a physiology professor. I made this channel to help my students learn physiology on their own time, at their own pace. To help others do the same, I published my lectures.

This video quickly reviews the full action potential in neurons, focusing on the absolute and relative refractory periods. I also review how certain anesthetics (like lidocaine) work and prevent the sensation of pain. Happy physio-ing!

This channel is dedicated to helping students and instructors navigate physiology by providing full access to a semester's worth of physiology videos. Some videos are entire lectures while others are one part of a lecture. You can follow through the video series in order by following the numbers that are in each video title. For instructors interested in using these lectures to "flip" your course, please contact us!
