Action potentials are the signals our neurons use to communicate. But, what are they exactly? What are the steps? In this video, I take you through an animation of the stages (resting membrane potential, depolarization, repolarization, and refractory period), show you what you can write if you’re taking notes, and breakdown the membrane voltage graph of the action potential.

Action Potential Digital Manipulatives:
^Make a copy of this Google Doc, then open channels and move ions around to practice modeling the stages of the action potential.

Man, you're too good. Your graphical explanations are the best. Got this concept in no time

[aimeecarolyn]

I've been watching many videos to try to understand this and I am marking your channel as my go-to. Thank you for your clear explanations and humor. Very enjoyable and very clear.

Excellent content! I'm studying to take the TEAS exam for nursing programs in California and all of your science videos have helped me understand anatomy and physiology concepts much better! You possess the ability to explain the material with the most important quality required in pedagogy--clarity.

I’m so glad I came across this channel ☺️. I was literally planning on dropping out

[melissacurry]

You're wonderful! Thank you for making a confusing topic easy to understand. I have watched so many of your videos, and they are all amazing! Keep doing what you're doing. I imagine you have helped so many. Thanks again 😊

English is not my first language but I understand this video more than my teacher

[YuyaD]

This is the most mindful [like] I ever give to someone. thanks for the explanations

[Eyerow]

Finally been able to understand this! Thank you so much for making this possible.

[Ano]

I’m the top of my anatomy class because of you, thanks ❤❤❤❤

[EllieLahamar]

Sir, I can't thank you enough for this channel. I showed your channel to a lot of people.

[twill]

Man, where were you when I was taking A & P I and II on steroids??? Hahaaa! I love it!!! Thank you so much for what you do. I was given (when I finished my nursing residency) and still have the exact same "Neuri" stuffed doll.

[jazz]

thank you for saving my time and life once again

[SisiMcCall]

I love your videos, they are helping me so much with my notes and give me a way better understanding of how everything works. I struggled with understanding the action potential and in 10 minutes you made it super clear. Thank you so much!

[westcotter]

These videos are great! Thank you for making them!

[mediatrixebisi]

thank you for always making easy with these beautiful pictures

[sihyunoh]

I was so confused before this video. you are the best!

[jungandrea]

Oh my gosh! Thank you so much. This is super amazing and I come to understand better about the concepts of action potential

[kayisra]

Thank you for helping me get an A in my A&P class.

[zainkadhim]

Thank you so much! This is so helpful!
