I've literally watched like 7 videos on UA-cam explaining the same exact thing. Yours is the ONLY one that really breaks it down so that even a child can understand. THANK YOU
Thank you for such a great video! The Q&A portion at the end is so helpful for both making sure I truly understand it, and for coming back as a review to make sure I STILL understand and know it. Also, thank you for fixing the subtitles, it really helps the hearing impaired and deaf med students in the world! Quiz starts at 16:44
I am a student at another University. No matter how many lectures I sat through or how many videos my professor posted, I was struggling with this. This video helped me understand it a lot better. Thank you for making this video, I appreciate it. Hopefully now I can pass my exam in 2 days. You have saved me!
The ABSOLUTE best video on UA-cam explaining action potential. You are literally the best teacher ever for simplifying an otherwise complicated process. Thank you x a million!
You are helping me so much! I've been feeling so stupid in a class full of smart kids and now I just realize I needed it explained in a clearer way. I wish very Professor spoke in such clear cut terms as you. Thank you and you can tell by the comments you are literally helping people from all around the world. You should get an award. You make the student world a better place.
Thankyou so much Mr Hartung, you are truly amazing and have really helped me out in my preparation for my exam all the way here in Australia! Thankyou so much for all your kind help :)
thank you so much. this is so helpful and I love the way you pause to let me think about it and figure things out, you're not rushing and it's just perfect. thank you again!
I MUST say I completely agree with the previous comment. Thank you for explaining this so thoroughly and in such a simple manner that even a child can understand it. I have also watched several other u tube videos and they all talk really fast and are so detailed that I get lost in the process. I appreciate you talking slowly so that my brain can grasp and comprehend the process and also for reviewing over the whole process again to instill the process firmly in my mind.
Loved how you first explained the whole theory and then asked questions regarding it.The fact that i could answer all your questions correctly made me happy .Thankyou so much.
Thank you so much! I'm so lucky to have found this video. Your explanation was fantastic. I also enjoyed the questioning at the end & reviewing. Explanation was so well done I was able to reproduce the graph & diagram and talk myself through the action potential process. Just have to repeat it a few times to get it into longer term memory! Thanks again!
Dr. Hartung. You are the best teacher I have found so far. Your students are blessed to have a teacher like you and thank you for sharing your knowledge with us on UA-cam.
Thank you so much. after watching different videos for weeks, this is the first explanation that makes sense. I will watch this over and over till I can explain it myself. Thank you
everybody saying "i bet you had studied so many notebooks like a parrot to get into med school" *me just watching Ren Hartung videos with my manual open and having fun knowing that i have more knowledge than my competitors*
Thank you so much for this! I took a test and had to explain this and I didn't do too well explaining so I went on here to try and understand it, this was so helpful!
This is the only UA-cam presentation on action potentials that I actually understood. I'm looking at all your youtube lectures. Thanks for communicating this very difficult step by step. Kudos
Lol thank you very much! :( I'm very troubled in understanding electrophysiology for medicine but this video gave me an idea all about it! I finally understand it i'm more of a visual kind of learner. :D
Thank you so much for this video, it has given me a much better understanding of action potentials and a bit more confidence to write my assessment on what an action potential is.
