" Cause that's what you get in Ninja Nerd Science" LOVE IT!!!!!
YOU GET E X T R A
Great video! Since we all are ninja nerds, another thing: it takes 2 molecules of ACh for each nicotinic receptor. And ACh always binds in the alfa protein of the channel.
thank you for this information you wanna say that 2 molecules of ach are required to open each nicotine receptor
Thanks for sharing!
Literally no one
Ninja nerd : see this cute little thing out there , that's a very very imp protein and that's the 2546th protein in this video
I cant thank you enough for these videos!! I learned more from you in the last 3 videos than having spent 3 weeks of sitting through my physiology class. Hugs! 😊
Saving my degree, one video at a time ;D Thank you!
People like him should be supported as much as possible
By the time Zach finishes telling the interesting story, some of the very complicated concepts in medical science is crystal clear and his quick recap, help us keep the concept alive in our hard disk
The best videos on NMJ that I've found (and I've been through a dozen). Thank you for this comprehensive lecture. You taught me more than my Professor.
Who had the nerve to give this a thumbs down?
Dr. Najeeb
@@RepaerTool YES😂😂😂
Lol nerve.
Dr Najeeb is a legend , the only thing i don’t like is his accent , while this guy speaks much clearly
Legend has it his son did
thanks a lot bruhh , as a medical student we have lots of things to study but your videos really helps a lot to save our time and clear all concepts and cove each and every perfectly. its better than reading any books ..... keep it up man
one day i would wanna teach the way you teach!!! . amazing teacher you are :)
Great work man! Yours are one of the best videos on YT on these topics. I would add that in order for the nicotine receptors to open, TWO molecules of ACh need to bind to it.
You are the BEST! You are truly GIFTED! Please keep doing more videos especially about neuroscience and neurology. MANY THANKS.
I can't Thankyou enough for how well you teach, I literally come here after all my physiology classes because this is your language 👊👏👏👏👏Be blessed.
Loved this guy! He has such a passion in every lecture he makes.❤️
What an amazing teacher! Wish every teacher taught like you. Cleared all the concepts.
I FINALLY UNDERSTAND THE SARCOPLASMIC RETICULUM! PRAISE ZEUS! AND THE GUY IN THIS VIDEO!
Yes, my brain hurts, but I will have a much better recall and understanding this semester and can hope for another high distinction this semester! This is way more useful to me than textbooks and droll lectures. I'm so grateful for RUclips because this stuff wasn't around when I was first studying this stuff!
Thanks!!!!
I love your videos!!! I'm a visual learner and these videos are perfect for me, thanks for your explanations and all the details I really appreciate it!!!
I'm from Brazil and currently a pharmacy student. I just want to thank you for helping me understand all these things, you're an awesome professor🙌💕
Have a test in 2 hours ans this was so helpful in summarizing most of what I needed to know!
These video lectures are the most impressive videos that I have attended. I am doing a course on Neuroscience, but I always watch these in addition as they are so clear and also detailed. I cannot get enough of this!
Chiropractic student. Youre saving our butts out here too, thanks!!
Please never stop making these videos, they are insanely helpful! Amazing content and so grateful to have come accross Ninja Nerd!
Thank you so much for putting it all together for me! These videos are wonderful!
You are studying for which exam?
The best professor I never had
very nice video and you are the real exam savior for the medical students. I am in my 3rd year of medicine and loves watching your videos. thanks bro.
Im a first year medical student because of coronavirus we are taking online classes which are not really helping me, but watching your videos giving me hope that I can do it. Thank you so much.
This is awesome!!! Now I can finally understand physiology. Thank you so very much for all your videos.
Ninja Nerd Science is so fantastic! Your videos are awesome.
You are so good at this. Like, someone can see how deeply you know this and how you like the subject. Thank you a ton!
I am making a list of everyone I want to thank on my graduation ceremony. This channel is my number one. Thank you so much
"because that's what you get at ninja nerd science... you get extra!" LOVE IT. Honestly the best lecturer I have ever come across.
Long Live Ninja Nerds!
You are my LIFESAVER!!!!! Would never have understood Physiology without you
Prof. Zach you are amazing !!!
You are amazing! Thank you so much for taking the time to make the two videos on the NMJ. I understand it so much better now!
These videos make my study easier than before, thanks a lot ❤❤
thanks a lot for your time and hard work! it 's really worth, you're amazing, Bravo !
awesome as always, super specific yet understandable and fun, thank you !!
dude amazing job with this lecture, kept my attention the whole time!
Excellent and accurate presentation of this knowledge. Really liked it.
"Mm that's a nice color" haha It was! Thanks for this terrific contribution.
Thank you so much for your hard-work!! Learned so much from these videos, I am so glad that you got more, I will be around watching them all for my advanced patho class :D
what a nice teacher, so specific and detailed. I love your video very much
absolutely Awesome - Thank you for your great explanation, This is why i love and support the Ninja Nerd Lectures
We are watching this great video from Med School in Paraguay! Some classmates don't speak english but I personally find this video very useful, I offer my help translating this to spanish for them if you want me to! Just throw me a message.
THANK YOU!! Couldn't thank you enough for taking the time and effort to make these videos.
It was absolutely fun and enjoyable, thanks for being there, you're a miracle that happened in my life ❤❤
Literally a life saver. THANK YOU!! You explain this in a way that makes so much sense.
Magnificent explaining as always. So lucky to found this channel.
No words can thank you enough, keep making does amazing videos.
You are really making an extra effort to teach us things,here to help us to actually learn sth and that’s really valuable for us, students. Thank you, for real.
its crazy the 3 parts of ur lil series is 1/3 of ONE of my lectures. We do a chapter a day. Exams every 2 weeks, and so much detail expected obviously. if it weren't for your videos I would still be in my bathroom crying lol. u saved me!!
I really like the way you explain and teach, I don't know what it is but you explain very thoroughly and also allow time and momentum for people to soak in each new term that is introduced. You helped me a lot thank you! :)
Saying thank totally is not enough ... but thank you from deepest of my heart for that great explanations .... teachers of university must know how to teach from you ❤
i am likeee wowwwwwwwwwww, my concepts areee damnnn clearr nowwwwwww!!! thankkk you soo very much dude, you teach theeeeee best! lots of lovee and supporttt
this is pharmacy made easy for me , had a lot of lectures but could not make any sense from them until i listened to this video, thank you for the time u invested into these videos
Cant thank you enough for this videos. You are the best physiology teacher ever. You deserve million millions of subscribers
I love Ninja Nerds! Shout out to all Ninja Nerd team!
You helped revising my lost concepts
U are a perfect doctor!🌍
I can't believe this is free. Thank you so much from a struggling college student!!!!
Excellent job. That type 1 nicotinic receptor you mentioned actually has an epsilon subunit rather than a gamma subunit. The gamma subunit is located within the first type of extrajunctional nicotinic receptor.
+1 on this, although as always another excellent production! The receptor described in the lecture with a gamma subunit is a fetal nicotinic receptor, which functions slightly differently from the mature receptor. The fetal receptor can proliferate outside of the neuromuscular junction and pop up anywhere on the cell membrane as a result of certain conditions. In addition, they are more sensitive to depolarization and the channel stays open longer. This can be a life-threatening issue in response to certain drugs like for example succinylcholine as massive amounts of potassium can leak into the plasma due to the abnormal kinetics of the channel.
Hoping it makes sense? You are blowing my mind!
I feel like giving you a big hug right now. 🥺 Thanks very much!!!
I don't skip ads because I can't give much back to him for the knowledge he gives
What a video sir !!!!!Thanks a lot for your sincere efforts.
