Very nice video Leslie. Quite informative and it will help my students understand muscle contraction a little bit better. Looking forward to the next one!

Great video - as usual - I will recommend my vet tech students view it to review muscle contraction in Physiology course this semester! Thx!

You are very much welcome, Rose. I’m glad you find it useful for your class.

I just ran across your channel. This is pretty awesome stuff. I'm an athlete and coach and love learning about the nitty gritty of how things work in hopes to find ways to optimize those interactions. I watched a video of yours from 2011. This video is a similar one, but higher level detail.

Thanks a bunch, Tyson. I'm glad you got value from it and I really do appreciate the encouraging comment. Make sure to subscribe for more of this fun stuff 😃

Leslie you are doing your job in a much pretty way. It's very impressive. Your vedio are full of information. Before I came across this awesome channel I was using the internet just for watching shit things like dramas and many more. But now watching your vedio has much fun than watching a movie or a drama. Keep it up 👍

Thanks Muhammad. I appreciate that very much. Glad to hear you're finding value in the videos. Stay tuned for more.

Are you working on that Creatine video mentioned. Maybe it was another video. Can't wait.

Ahh shoot. Thanks for the reminder, Tyson. We decided to move on to some other content, but I need to go back and make that one since I did mention it.
