How do Muscles Contract? Sliding Filament Theory | Corporis
HTML-код
- Опубликовано: 26 июл 2024
- Your muscles contract thanks to something called the sliding filament model, sometimes called the sliding filament theory. It involves a bunch of tiny proteins, actin and myosin, sliding past each other in an orchestrated little dance that every anatomy and physiology student has to learn.

Hi, I’m Patrick. I’m a freelance science writer based in the San Francisco Bay Area. I hold a bachelor’s degree in Athletic Training and a master’s in clinical exercise physiology. I used to work in the clinical setting as a certified athletic trainer, physical therapy aide, and a certified strength and conditioning specialist. After working in the clinical setting, I went back to school and became a teacher. The goal of my content is to help normal people, not just pre-med students, learn about the human body. That might mean explaining a topic from an anatomy class or exploring a topic from medical history.

i never saw someone explain something so well i finally understand this also the animations are amazing!! thank you!!
This comment makes me so happy, thank you! Best of luck in your studies :)
The first thing that got me interested in biology was ATP Synthase...followed immediately by the whole process of muscle contraction. Realizing how much of biology is little machines has just blown my mind. I do wish I would have had your video when I first started learning, it was very "clean" I guess I would say. It was a good overview without too much of the nitty gritty.
pghparkins That’s exactly the point of this one. More of a traditional, curriculum-oriented first look at the sliding filament theory for students
@@Corporis I might have to send this to a couple science teachers in my area!
Hannah Paige you’re the mvp, thank you
If Cooking with Corporis doesn't become a thing I will delete RUclips
Let’s start a petition.
Lol, chicken heart dissections next week I guess!
I think his dig about the heart being the only important muscle was directed right at you Medlife Crisis. I think your next video needs to have a dig at physiology. That is what the science youtube scene is missing, dis videos.
@@hannahherrmann4921 That's amazing you're the best
I wish I had you as my professor, this is fantastic! Waaay easier to understand that my Anatomy book
Happy to help!
My man when I see you have caught me more in your short videos than my anatomy professor has in whole lectures I mean it I thank you so much for what you’re doing on this channel
Glad to help. Best of luck with your classes
I agree with all the comments. grateful for how precise, detailed, accurate, and in-depth your videos are. brilliant.
Love the videos you post. Always explained so well that I can understand. Keep up the great work!!!
Gotta love that Binging with Babish reference. Combining two nice channels into one.
Keep up the work! It's honestly underrated.
Thanks a ton, means a lot.
Thank you so much! Your level of dedication in teaching is much appreciated.
you are just a fantastic teacher you explain the hardest things in the much easiest way. I spent my hours with videos that explain very long but with you it takes only few minutes. Thank You so much.
You have no idea how great this video was!! I feel so much better on the concept. Thank you!!
Glad it was helpful! Best of luck with your studies
i cannot handle the niceness this guy is radiating
Appreciated
I can't believe I just stumbled across your channel. Your subscriber count is VASTLY lower than it should be given the educational and productional value of your videos. Your presentation style is also very soothing (this is particularly nice considering I have a grad-school Biomechanics mid-term tomorrow lol). You've earned a subscriber.
Wow, thank you, that's awfully kind of you to say. Best of luck on that midterm!
How does this guy not have more views, literally a perfect video
Thank you! That kind of comment means a lot
I agree!
So so grateful for your videos! 😊
I think you are the frist western person which gives both of detailed information and free notes at no attachments...❤
thank you SO MUCH for the subtitles. seriously, i appreciate that so much
My pleasure! Do you have any requests for languages to translate captions into?
Hello! I'm currently learning about human anatomy, and more specifically, about the Nervous System and the Motor Unit. This video is super helpful. Thank you for creating it!
Waaaaaayyyy more helpful than so many other videos I have watched on this topic.
Thank you so much for these videos. You have been an excellent resource for my anatomy final on muscles. You helped me understand the concept of muscle contraction, which helped me ace my final. I was struggling too!! Your explanations along with the real-world application was amazingly useful. THANK YOU!
This is amazing, I’m studying for my paramedic class and this video taught me sooo much. Thank you for this like seriously lol
I'm a massage therapy student. You are getting me through A&P. Thank you!
you made this topic insanely easy to understand. thankyou so much
Simply put, you made it super simple. AMAZING,oh and the food analogy spot on!!!👍👍👍👍👍🎯
Thank you kindly! Simplicity is the goal
Thank you again! These playlists on the skeleton muscular system are amazing 🤩 as well!
Also, I have shared with all my nursing student🩺💉🧠 friends your videos and they’re loving too! Now in our study groups when we get together(virtually of course 😒) we always chat about “who watched your latest video on what topic” 🤓 you make learning a very hard course super fun hope you keep making more videos!
I appreciate the shares and continued support. Thanks Brandice
Such a creative way to teach muscle mechanism basics! Great video!
Lorrie H thanks Lorrie, it was a fun one ☺️
Great vid to recall stuff i studied recently!
Grateful for ya, Patrick :)
Aww thanku for the study material in the 'doobly-do' - i was smiling as John Green's face came to my head.
John Green was (and still is) one of my biggest influences. DFTBA
@@Corporis :) that's really good to hear.
Don't foget to be awesome, u too 😎😉
Thankyou so much..! Leaving a comment for the algorithm and to come back to the videos later. Subscribed.
you explained it so well !!! thank you so much ily
Superb video 👌 love the way you explained the concept 👍💯
This is an awesome video explaining the sliding filament theory. I've watched 4 other ones and this one was definitely the best. 👍
That means a lot, thank you! And best of luck in your studies
@@Corporis Thank you! 🙏
thank you so so so so so so so much I never understood SFT before this you're a hero!
haha, my man! Great video and well explained. I absolutely adore science
I appreciate your regard for reasoning behind actions over simply memorising the process.
I appreciate the kind words
Thanks for this video! the way you explained the topic is easily understandable :D
Glad it was helpful!
this saved my life. best explanation ever
very good information. Love watching
So my muscle fibres are like velcro. That makes my running shoe straps very meta
PlayTheMind Brooooooo
Thank you! Great explanations.
Man, you just helped me understand this. Thanks!
No problem!
this did a better job at explaining the concept in just 7 minutes than my physiology professor in med school... lol
I feel so much more confident about my exams after watching this video, Thank you !!
This made it so much easier to understand I legit cannot thank you enough
Happy to help. Best of luck in your studies
Omg I felt like I was watching a Binging with Babish episode in the beginning 😂 good job, I understand this topic now!
This video is fantastic! Thanks for sharing!
Glad you enjoyed it!
Great explanation, thanks for this.
This was so helpful thank you so much💕💕💕
This video was the perfect review for my anatomy test tomorrow. Thank you so much. This video is so well put together and is explained very well. Now I’m gonna watch this on repeat so I can get that A.
Best of luck! You've got this!
this is great stuff, good job man! :)
Glad you like it!
Super good and simple ❤
that was short and sweet, thank you
Kiro you got it! Thanks for watching
this is absolutely so helpful! Thank you!
Glad it was helpful!
Wow I understood this video better than the virtual text book.this was like listening to a kindergarten audio lesson and actually understood what you are talking about.thank!🙌🙏💯🤓
Very good and funny videos bring a great sense of entertainment!
i couldn’t understand this in class but with you’re video i have more understanding on it, i just need to watch this a few times , we are on this chapter.
This is amazing thank you🧐👍
I follow your other channel and I was so confused at first when i looked up this video for school. I was questioning whether this was your doppelganger or not. lol
i could cry!! you made things so much easier
Good! That's the hope. Good luck in your studies
I just found you and my first anatomy class is almost over😢 but THANK YOU. I struggle with understanding muscles!
thanks man, ur amazing!
Definitely just expanded my understanding!
Best of luck out there!
This was very very helpful
This one has always been a tough one for me to learn but this was very useful. thank you very much
You're very welcome! Best of luck in your studies
you are just amazing!!!
very helpful. thank you sooooo much
You're welcome!
oh my god this helped me so much thank u
It all makes sense! Thank you!!!
I got you!
@@Corporis amazing job and incredible work! You are appreciated!
Thank you
Thank you for making this, I may have just passed my Anatomy test bc of it
I will think about all of the info in this video while I workout.
Samer Kadoura yay!
Well said
Guys, if you can support his Patreon, please do so. In that way, we can help him, and in return, he can make more anatomy videos, so that, us, anatomy enthusiasts, will no longer dread the monotonous tone of the hundred boring anatomy videos on RUclips. (It is not that I do not want them, it is just I do not get the same dopamine kick that I feel when watching your videos as opposed to them.)
I really appreciate the encouragement, thank you!
Thank you so much corporis, this helped so much, but the chicken.... needs some seasoning 😂
Amazing video, Sounds and looks like Vertasiam
Genius❤
How are you doing @corporis
Wishing you a happy new year
Why don't you continue uploading the videos they are fun like this one the 'HAM'
Thanks so very much for sharing this informative video. The explanations are so clear. Do you teach in a school? Have you written any books! I am cutting in a MS program in fitness. It is tough. Your video was a great help. I am a vegan, but your illustration was fine with me.
Hello and thank you for your amazing videos. I wondered what happens in the sarcomere during an eccentric contraction. So..are the myosin and actin still pulling the Z lines closer together but the titin is stretching to allow the muscle to lengthen? Or is there a gradual sort of slippage between the action and the myosin as myosin is ripped off the action? And what actually causes the muscle 'damage' associated with eccentric contractions? Thank you again.
Entertaining intro
Hi! Thanks for the video. Does actin stay in place while myosin moves?
Myosin! My thesis was about myosin! Gahhhh I love the sarcomere!
"And that's fine if you think cardiac muscle is the only important muscle there is." I feel personally attacked.
Thanks bud, I appreciate you and your love of myosin
I can't believe anatomy became my new obsession lol that is so weird.
Welcome to anatomy. It gets pretty heckin' awesome.
Just slowly falling into obsessing anatomy, but I can feel you,
awesome
How do you not have 1000s of views? In the old days the Crossfit community would have been all over this stuff. It was all about understanding fitness at the most basic level. Now it's just people who exercise and talk about themselves exercising - sigh. Anyway, I always wanted to know this better and now I do. Thank you!
Interesting video. Who knew chicken breast could be so useful as a learning tool?
Maureen Kelly Thanks Aunt Reen. My sister was grossed out by the idea of it.
at te biginning i was getting it all well but at the ending im getting a bit confused :( maybe i'm tired i will come back later . Thanks for a good explanation.
Thank you so much for this video!!!! You did an amazing job at explaining how muscles contract. 😊
You're so welcome! Thanks for the kind words
"rigor Morris girl, it was rigor Morris"/"Who's Morris?"
Yo ur videos r awesome whoever I need to watch a video on something I type in what I want and ur name after
That means so much, thank you for saying that
Great
Those animations are amazing, how do you make them??
Thank you for the kind words! I use Adobe After Effects for all the graphics. It's tough to learn, but when you do, it's really powerful
@@Corporis oh awesome! i have to learn that eventually. your channel is very inspiring for aspiring educational channels like me :)
I have a question. At 5:46, you mention the phenomenon of rigor mortis. But: if a sarcomere at rest is RELAXED and NOT contracted, and ATP makes the muscle contract and stiffen/firm up, then by that logic, shouldn't the total lack of ATP lead to total limpness instead of stiffness?
Also, if during contraction, the I band shorten and the Z discs get closer together by moving towards the opposite Z disc in and center of every sarcomere, what happens in adjacent sarcomeres? Is there a 'center' that all Z discs in the entire muscle, slide towards? Cause there's no way you can move all of them closer while keeping the lengths of the A band and I band the same length.
how do I get to the study guide?
Memerlukan lebih ramai orang jadi sebarkan video ini lebih banyak
Image how cool he would appears when his friends visit him and he elaborating these anatomical concepts to them ..
He could join other communities
He is missing his fucking viewers.
I have a test next hour and I haven’t studied at all wish me luck😮💨
How do we access the study guide mentioned?
I was wondering the same thing as I was watching on my phone. However when I watched on my computer- I found the links right under the video!
Watching this while eating.
Next, oxidative phosphorylation
How could you cook my kind Mr. Kelly.
LOLOLOLOL Ohh my gosh I forgot about the chicken thing!
