Thank you for sounding so happy and excited, it really makes a difference in the learning experience. It makes learning these difficult details so much more pleasant. Thank you for cheering up science nerds everywhere :)
+Leslie Miller Thank you for appreciating that - it's subtle, but SO important! Science IS fun and wonderful! I love my profession and my students, so I'm so glad to hear it comes across. :)
Med school professors could not explain this easy concept and you did it in ten minutes. Great researcher does not mean great teacher. Learned that the hard way.
WOOOOOW!!, this is beautiful!!. I have been reading this in my text book, my lecturer`s slides and my tutor`s notes but it made no sense!, I just couldn`t distinguish between excitation-contraction coupling, sliding filament theory and cross bridge cycling but now I get it, all thanks to you Prof!!, your work is much appreciated!.
you are an amazing professor, I love your tone of voice but what I love the most is how well you explained this. I wish my professor loved to teach as much as you do!! My respects for you ma'am.
This video helped me out so much! I'm in a one month physiology course and it's so hard to learn all of the material before an exam in 4 days. One question - does this also happen in cardiac muscle cells?
That was very interesting. I appreciate understanding whats going on at the molecule level with muscle contractions. It adds to the mind muscle connection when weight training.
very thankful to your exciting video, it is really informative. It provides more knowledges about DHP receptor and RyR that in my textbook doesn't exist, hope you can release more such interesting video.
I think it is important to note that there is a graded/local potential started by the nicotinic-AchR by Na influx. This in turn, propagates to activate V-gated Na channels that make a new AP. The new AP travels down the T-tuble etc.
I've read recently that STAC3 has been identified as a (possible) fourth essential EC coupling protein and it may couple CaV1.1 with RyR1 for calcium release in skeletal muscle. This would explain observed myopathies in patients with STAC3 defects. Some good info here: www.pnas.org/content/114/2/E228
This video is very awesome. However, I do have a question about the dihydropyridine receptor. Currently, have researchers been able to better understand the DHP-R (a voltage-gated L-type calcium channel) and know that it opens the ryanodine receptor by releasing calcium into the cytoplasm which binds to the RyR to open it and release calcium within the sarcoplasmic reticulum? I'm trying to piece everything together between UA-cam videos and my textbook.

Amazing!!! Grad student, you explained in 10 mins what takes most profs hours. Thank you so much for posting. I love your format.
LOVE THIS EXPLANATION - YOU ARE GREAT - PLEASE KEEP CREATING CONTENT MEDICAL STUDENTS NEED YOU!
OK I WILL - THANK YOU FOR WATCHING!!! Good luck in med school!!!
You don't know How much thankful I am to you
Your clarity and optimism is greatly appreciated.

I am SOOO glad you found this helpful! Thanks for letting me know!
Your voice is so sweet I could be hearing you all day, uh, and very clear explained.
you are an amazing professor, I love your tone of voice but what I love the most is how well you explained this. I wish my professor loved to teach as much as you do!! My respects for you ma'am.
Wow, thank you! Thanks for watching!!!
finally someone explain the mechanism of DHP simply and professionally :)
I'M SO HAPPY I FOUND YOUR CHANNEL
Wow! I had completely misunderstood the entire thing when my professor explained it, but now I get it. Thanks a lot!
Thank you. this is very clear to me, especially your easy words and sentences make it easy to understand.
Glad to hear that!

This is the best physiology video I've ever seen...
Thank you sooooo much. The animation and dialog were exactly what I needed to get my head around this concept! Your videos are great!
THANKS SO MUCH YOU'VE LITERALLY SAVED MY LIFE!

So happy to hear that!
Thank you so much !! I couldn't find a video or textbook explaining the sequence in chronological order - thank you :)
Wonderful lecture hope that there are more professors like you,keep up the good work.
Thank you so much! Thanks for watching!

Thanks for the heads up on Open Stax.... I was able to get a couple of useful textbooks...thankss :)
You make it sound so easy , i marvel your way of explaining thank you
You are welcome! So glad you find my videos helpful!
The best explanation better than my professor
Love your channel. Really helpful and easy to understand. Keep up your great work, I and many others really appreciate it!
always coudn't imagine DHPR and RyR .....made it a bit clear...thanks.......please keep making more heplful videos like this....
Finally i understand the mechanism. Thanks !!!
I'm so glad to hear it! You are most welcome!!!
short sweet and to the point. very helpful keep them coming!
Thanks a TON! You explained so perfect and simple. I have never understood it better than now!
Really great video, thanks! Made this physiology chapter super easy.
Thank you soo much for your helpful explanation!!!
Glad it was helpful!
Excellent explanation ! 👌👌
Thank you 🙂
Hello I was wondering if STAC3 could make its way onto this video. This was great!
What os STAC 3
WhT is STAC 3
A skeletal muscle specific protein that is crucial for DHPR/RyR coupling
Thank uuuuu so much you are seriously a life saverrrr!!!
what an amazing explanation!
Thank you, now I understand how excitation-coupling works.
You're welcome! Thanks for watching!
ThePenguinProf I shared with my class!
So helpful. Thank you so much.
Adipoli mole ushaar ayikunnu 👍👍👍
Great drawing! Thank you!
This was super helpful
I'm so glad!
What a great teacher! Could you possibly tell me what a STAC3 defect affects the Ca+ and the muscle contraction?

very nice explanation!!!! thanks a lot
This was amazing! Thank you so much!
thank you so much. this was the most helpful explanation.
I love your work!
No skipping ad😁 Love the of fairy penguin 😁😁
Fairy penguins ALWAYS.
please do for cardiac muscle...
Thank you so much!
Thank you, you helped me a lot!!
this is amazing, thank you penguin prof!
Great video 💕
Loved it!
thanks !!! really helpful

Extra Thank for the link
wow amazing! thank you so much! much better then my prof aha
Only worthwhile video on excitation-contraction coupling on UA-cam.
I love you thank you sooo much!!!
dis shit helpful dawg
amazing really
thx
You have such a lovely voice
I'll let my vocal couch know you said so! Thanks!
@@Penguinprof I meant voice modulation 😀
very helpful thanks thanks thanks
So sweet voice!
thank u so much! u saved me!
wow. just wow. i can learn how to build a rocket ship with this professor.
woòooooow ...... very helpful. .... hundreds thanks
+Manal Kanouaa You are so welcome! Thanks for watching!
Fantastic
Thank you so much 😀
Good. Thank you
You are welcome!!!
Beautiful ❤️
Thank you! 😊
What happens when nicotine binds to those receptors ? It does not cause muscle contraction ?
So how is the excitation-contraction coupling related to the sliding filament theory?
it's good🤗
I love you
Awww... thanks!!!
Thanku mammmmmmm
You are soooooo welcome!!!
Wooooow
SOOOOO glad you like it...
❤
❤️🐧❤️
Da best
how muscles grow???
Too FAST Too MUCH ....from a pro who has studied this stuff for a long long time
Thank you so much!
thank you!!!
thank you so much!
