    Knowing something and being able to make others understand this is something totally different ... And you my friend, whoever you are, have a talent in doing this ... Everything in your narration is perfect: from your voice to your drawing and making others remember the knowlege included in your video without having to study it again. So I hope that u are some kind of professor or teacher in a university because you have a talent in that. Friendly greetings from Greece.

    @ladynottingham89 9 лет назад +60

    My professor just started to mention terms like depolarization, repolarization, and action potential without explaining what those meant. WTH?! Thank you for simplifying the concept behind the terms. Most of us learning this are undergrads LoL maybe some professors forget this and start throwing medical jargon at us like we already know what they mean.

    • @MonkeyDLuffy-xr4fl

      Really the first professor to explain action potential properly was in my first year of med school. Actually a lot of topics my undergrad just told us to accept w/o explanation were covered cause I ACTUALLY HAVE TO UNDERSTAND THIS TO KNOW IT. cough still annoyed at undergrad.
