042 How Calcium ion release results in Muscle Contraction

www.interactive-biology.com - In this video, I show how the release of Calcium ions from the sarcoplasmic reticulum results in skeletal muscle contraction at the level of the sarcomere. Enjoy

[@DrChaMSUMD]

I've learned muscle contraction a million times, but I've never UNDERSTOOD it until today. Thanks for the great video!!! =)

[@juice28rsx]

same here this vid is amazing

[@izaiahralph2774]

i know I am kinda off topic but do anyone know a good place to watch new movies online?

[@everettleonel2844]

[@izaiahralph2774]

@Everett Leonel Thank you, I went there and it seems like a nice service :) Appreciate it!!

[@everettleonel2844]

@Izaiah Ralph No problem :D

[@melanienguyen4188]

Wow I kept reading my textbook over and over and reviewed my notes...but after watching the videos I can finally understand and visualize muscle contraction. Thank you so much! You are the man!

[@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.

[@fal00da2]

My professor sucks and only puts pictures on his slides! He made us buy an outdated book and never explains anything! You totally just helped me understand this concept with just one view of this video! Thank you SOOOO much!!!

[@informme152]

Your lecture really helped me alot in my lab presentation and I want to say a big thank and God bless you! Please, keep up the good work. You are a very unique teacher; your ways of teaching is exceptional. This is my first time watching a video on this topic and the way you explained stuck in my head.

[@KSP_1776]

Thank you so much!! Your videos are seriously helping me through my anatomy course right now. Thank you for making these.

[@sxyngel]

WOWOW JUST WOW. I DIDNT UNDERSTAND anything my lecturer woman thought me at university about this. and it covered a whole chapter of textbook. YOU JUST SMASHED EVERYTHING BACK INTO MY MEMORY VERY EASILY THANKS :D REALLY!

[@shanemcinally7092]

Awesome video, I really like that the instructore went at a slow measured pace, it made it a lot easier to get memorize the terms.

[@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.

[@rozhieee]

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

[@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!

[@InteractiveBiology]

@charlieding You're welcome. Glad you find it useful

[@magalilopez6390]

I had to learn this for my class, thank you so much for making it so much clearer!!

[@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 :)

[@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!

Your video is extremely well done and helpful, thank you for taking the time to make it.

[@InteractiveBiology]

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

[@denisdimitrov5995]

Thank you people im currently taking courses for a personal training in calisthenics and biology is a big part of it and i could not understand a thing when im reading it but explained in the video like this is much more understandable thank you so much!

[@samriaamor4210]

Man I don't even know what to say but I overstand this lesson very well finally thanks so much you are a life saver.

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

[@shontereed7472]

This video was GREAT ! It all makes sense now !

[@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.

[@alpoutoa]

Awesome explanation! I had to read two scholarly articles to understand how some ion channel mutations can cause symptoms observed in myotonia and periodic paralysis. I should've came here to begin with...(and I should've taken an A&P course )

[@timelessadventurer]

Thanks for saying you'll explain things in later videos :) These videos are so helpful :D!!!!

[@goldiecat123]

You are such a savior.

[@pleaselordmakemestudy9943]

HI i just want to say, thank you so much This video may be 10 years old BUT ITS STILL GOLD

[@InteractiveBiology]

Glad to hear that 😃. Make sure to subscribe for more 👍🏾

[@stratio10]

Excellent explaination! You saved my life with this

[@manunet85]

these lectures are amazing!!!thank you.

[@RapidBlindfolds]

simple explanation of quite a complex topic, well done!

[@InteractiveBiology]

Why thank you.

[@winterwonderland40]

I have a test on this info this Friday..this helped a lot! thank you so much!!! :)

[@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]

@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!

[@kitimakamwalee1750]

Awesome explanation!! Thank you for the great video!!

[@gudcharlotte03]

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

[@alinicole1201]

basic science with simple english thank you man

[@walentinkingstam8008]

What happens if Ca++pump is blocked? What is the difference in Smooth,cardiac and Skeletal muscle regarding extracellular ca++? Are all of them depending on them or is it just cardiac and smooth muscle? best regards

[@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?

[@Halahmed12]

IT HELPED. THANK YOU!!!!

[@carolinespec]

Great video!

Can you please tell me what software you use (where you do all your writing and drawing) interactive board kind of thing?? Great video helped a lot!!

[@pumpkinpie1067]

In terms of hypocalcemia causing muscle twitching/spasms and seizures. Can you provide your insight as to the physiological mechanism occurring ? Thank you

[@InteractiveBiology]

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

[@MissKarz]

Thank you very much. Very clear. I just learned what basically I needed to learn with this video. =)

[@InteractiveBiology]

You are very much welcome. Glad to help

[@kiransawant6802]

Very nice ! Keep it up

[@SheikhHammad]

Thanks a lot, you are just awesome. once again thanks

[@rafaeisenlohr]

SO HELPFUL!!!!!!

[@AfsheenAkbar]

is this the same calcium ions which contract actin and myosin filaments or it is the remaining calcium ions who pump back to SR.

[@VendettaofOne]

Your voice is beautiful!

[@friedshekin]

What would be the calcium ion in sarcoplasmic reticulum of his muscle after lifting many reps compared to lifting each once ?

[@sagek7949]

Thank you very much!

[@alibayrami488]

Thank you very much.
