Hands down the best video on cardiac muscle contractions Ive ever watched. I could never never understood how all of these processes were linked. Amazing.
Finally someone knows what to explain, not the bs high school stuff or 1h videos, everytime im confused it takes me hours to find a video, usually a sentence explained in 45mins, w additional useless stuff. Stay Guyton level man. Love this video
Was reading Guyton medical physiology and I couldn't fully get the picture untill I found your video. You don't just how much you've saved me. I would appreciate more if you uploaded more videos and soon. 😊
Hello, thank you for the video, very informative. I am currently stuck at the Ca2+ Sparks. In our lecture I just dont get, what the purpose is of that "spark". In your video it is number 4. at minute 06:00 "Spark" amplifies Ca2+ signal. I dont get what signal should be amplified by a that "spark". Does that calcium signal induce more calcium to be released by the sarcoplasmatic reticulum (RyR)? thank you in advance, Sub from me. Greetings from Switzerland
Hi, Sir and thank you for the video. During an 100m sprint, after the start, the muscle contraction rates needed are high so the slow oxidative Type I fibers cannot cope with this contraction rates. So what happens? We have violation of the muscle fiber recruitment rule which says that first the Type I are recruited, then the Type IIa and then the Type IIx?

Plz upload more videos!
This was amazing i want to learn more and more with you. Thank you so much for such a beautiful presentation!
PERFECT! Thank you so much!! I had been trying to understand this mechanism from guyton fot 2 hours
I just found this channel and I am amazed! Such a great lesson, hope you to upload videos more!

amazing video thank you , way better than in medschool
Excellent presentation, would’ve liked to see the role of potassium also displayed as it is crucial
So the only difference with SKM contraction is that the action potential in Cardiac contraction is provided by Pacemaker ?
this helped me so much! thanks I was really confused about this part
How did you animate your drawings?
great job

Excellent teaching. Especially cbcy.
This could be v helpful for those At even basic L.cardio training.
Great video.... It's easy to understand
Beautiful video. Solved my queries.
Wow! Great video!
This was amazing! Thank youuu😘
Excellent!
Great work
Thank you so much
Thank youuuu!
THANKS A LOT!!
