[xNeeluh]

You are the KING!! You totally just saved me - have a huge physiology test tomorrow, and even though I have to be up in like 3 hours, i'm beginning to have HOPE!!! :D THANK U! Subscribed.

[llonas29]

Thank you so much! Great video, you just saved me a lot of hard work!

[3ammourabek]

[h7mody7]

This is awesome ...thanks ...good explain😊✌✌

[mstice88]

how do i see the other videos before this one...this one really me...thank you

[InteractiveBiology]

@mstice88 Hi! That sounds excellent! We're so glad we were able to help and that you're finding value in them. You can find more of the videos at Interactive Biology. You'll see a complete list of Leslie's Biology videos. See you there!

[Dorothayyyyyyyyyy]

thank you so much you helped me pass my biology test :)

love you! keep uploading and helping!

[InteractiveBiology]

@Dorothayyyyyyyyyy Wow! That's excellent :) Definitely we'll be uploading more so, please stay tuned for new Biology videos coming very soon!

[lofo87]

Hi dude..awesome moovies that helps alot during the exampreparations...I just wonder what happens in a eksentric phase when the muscle is working in both phases..?

[InteractiveBiology]

@lofo87 Thanks for watching! Unfortunately, Leslie is too busy right now working on his site. Because of the overwhelming number of emails sent to him everyday, he's not had the time to get to each of them. He'll be adding more Biology videos though and will be tackling more topics and othe body systems. So, please stay tuned!

[rozhieee]

You have honestly saved my life so many times, you don't even know it!!!!! <3

[InteractiveBiology]

@rozhieee That's awesome! Glad to know the videos are helping a lot. Please stay tuned. We have more Biology videos coming very soon! :)

[ayshabkhalid]

i love these videosss! im at university and i find these much more helpful then lectures!

[InteractiveBiology]

@ayshabkhalid Glad we're able to help :) Please stay tuned. WE have more Biology videos to be uploaded very soon!

[kboppoG]

Thank you so much! This is really helpful

[InteractiveBiology]

@kboppoG You are very much welcome. All the best!

[ey7681]

awesome!!!but what about the ATP??



[InteractiveBiology]

@ey7681 That's explained in Episode 43. I see you left a comment there, so I assume that you got the answer :)

[Djalitana]

this is the very best video about muscle contraction on the web. I was very confused before and now all my questions are answered. thank you from the bottom of my heart.

[gudcharlotte03]

great video! it really helped me understand the whole sarcolemma and t-tubule connection! :)

[InteractiveBiology]

@gudcharlotte03 Awesome. Glad it helped. Stay tuned for many more :)

[laplesyrup]

awesome video!

[smogavc123]

in which program is this presentation made? its awesome :)

[InteractiveBiology]

@smogavc123 Thank you. I'm using Keynote on the mac as the presentation software and Screenflow to record my screen. They are both Mac-only programs. If you want more details on how I do it, send me a private message and I'll send you more info.

[charlieding]

@23philos Well thanks for keeping an eye out for them. God bless you too :)

[kinghoekstra1]

thank you!!

[InteractiveBiology]

@kinghoekstra1 You're welcome!

[Livinglifehigh]

thanks again. it seems everytime u upload a video im at at the same spot. right now we're learning about heart contractions like diastole and systole. but this muscle video will be helpful review for the test in 2 weeks!

[InteractiveBiology]

@Livinglifehigh That's Great. I'm so glad that the timing works out right for you. I'm posting videos about the heart starting on Monday, so that should be great timing :)

[Mekay999]

When will your next video be out?

[InteractiveBiology]

@Mekay999 Hi there. I'm heading back home today from my Spring Break Vacation. I will probably be posting the next video tomorrow or the day after. I try to post a few videos during the week - anywhere between 3 and 5.

[Mekay999]

@InteractiveBiology

That's great! I will definitely check back. These videos are really helpful.

[pjahanian1]

it was really helpful. thank you

[InteractiveBiology]

@pjahanian1 You are very much welcome!

[petercourt]

Very useful! Many thanks. Very much looking forward to the next video.

One question, in the original picture, with the T-tubule on it, is the sarcoplasmic reticulum the grey/blue substance wrapped around a myofibril?

[InteractiveBiology]

@petercourt Oh WOW. I can't believe I said what I said. I guess that's what Happens when you make videos in a rush. The tube that I showed in my drawing that I said was the Sarcoplasmic Reticulum are actually the Terminal Cisternae, which is an extension of the Sarcoplasmic Reticulum. The Sarcoplasmic Reticulum is the grey/blue substance that wraps around the myofibril. I will annotate the video to show that! Thank you!

[InteractiveBiology]

Ok, so here are some Spelling corrections for this video:

Fasicle should be Fascicle

Dihydropyradine should be Dihydropyridine

Ryonadine should be Ryanodine

Oopsees!

[joinmebowser9000]

I hope they would make myo sound like something like luigi in danish, if you know what I mean :P

[InteractiveBiology]

@joinmebowser9000 LOL.
