    One of the best scientific lectures/explanations on youtube... and I've seen a lot! Thanks.

    The Nodes of Ranvier act as amplifiers. The signal strength weakens as it travels down the axon but at the nodes you get a new AP. :)

    You've a knack for explaining things and making it interesting and understandable . The best video I ever watched on this topic. Thank you so much. Subscribed!

    I'm doing a correspondence course and I'm often left with questions and no one to draw me a picture, both literally and figuratively. I think I have it now, thanks for the great graphics!

    Hello Professor - I am getting a master's in human anatomy and physiology instruction (MS HAPI) and am researching ways to learn histology at the undergraduate level via the internet. I hope you don't mind, but after reviewing several other You Tube sites and presentations, I have chosen yours to represent instructional narratives with visual aids. Bravo to you for putting these together! I wish you great success.

    Youpiiiii. Eureka said one of your fans. Wow this sooo stimulating, it's like I made a discovery myself. God Bless you, you're amazing.

    I learned more in fifteen minutes of this video than two days of class...THANK YOU!!!!!!!!!

    Sorry... this is one of the areas I had to simplify because it's beyond the scope of most of my intended audience. In truth, there are at least 5 different types of voltage-dependent K+ channels in human axons. For details, check out the article by Reid et. al., in Journal of Physiology 518.3. Hope that helps!

    Hands down my favorite explination of the sodium-potassium pump in regards to action potential!

  • @AudreysFlwrs

    Your video was very clear and very helpful! I am teaching AP Biology for the first time and I was at a total loss of how to teach action potential until I watched your video. Thank you!

    If only my book could make the same effort to explain the action potential this clearly. Bravo!!

  • @ElTerrible2011
    @ElTerrible2011 12 лет назад

    I was a little skeptical at first when I saw that you were going to incorporate kids running out of class rooms and relationships with the action potential but you managed to break it down quite well when it was all said and done. Good job.

    The best explanation of action potential I've seen, and this is my third course studying biology in some form. Thank you for clarity and substance.

    THANK YOU SO MUCH YOU ARE SO AMAZING, I LOVE YOUR TOME OF VOICE, THE ANALOGIES UTILIZED IN YOUR VIDEO. It has made it that much more comprehensible for me, in my case returning to school after many, many years away being a mom! It's makes perfect sense!

  • @Steroidsman123
    @Steroidsman123 12 лет назад

    16 minutes ago I didn't understand action potentials...now I do! Thank you very much - I have an exam on tuesday (at GCSE level) so although for me this is in a little too much depth, if a question on action potentials comes up, I think I'll have a much better understanding.

    you say that the K+ channels are always open. Than how do you explain that the repolarisation is much slower than the depolarisation?
