I feel your pain, but did you know that you can make the video play more slowly? If you click on the gear shaped icon under the video, it will give you a choice of speeds to play at. You can also turn on closed captions, and turn the voice off if you wish.
@@ahadzx8875 I think you are correct, and multiple sarcomeres are then stacked and connected one after another within the myofibrils, as far as I know so far.
The myosin motor domain is what's doing the ATP hydrolysis. Myosin with no ATP bound is locked to the actin filament. ATP binds the myosin head, causes conformational change in both the head and lever arm, releasing the head from the filament and swinging it forward. ATP is hydrolyzed into ADP + Pi, which causes another conformational change in the head, increasing its affinity for actin, causing it to bind to the actin filament again, this time forward from where it was at the beginning. Pi is released, which causes the lever arm to return to its original position, pulling on the actin filament as it does so. ADP is then released, and another ATP binds the myosin head to release it and start the cycle over.
Can someone explain this to Me If we strap our hand to a machine which helps us move our hand move in and out and we let loose of it then how is it moving because we aren't sending neuro signals meaning the sites of bonding are still closed how is the muscle still contracting then??????
Ca 2+ not Ca +. Acetylcholine = uh see - tul or uh-see-tl. Named after the acetyl groups in Chemistry. Not ass-e-til. Excellent illustrations + a few corrections in the voiceover = perfect.
There at the end..my muscles are not able to relax back. It's hell. On any activity when I finally get loose (usually in water floating and stretching) it takes only a few minutes and i get super tight again. I had t9t10 damage in spinal. Got one leg paralyzed but I was, am able to get that leg working after 3.5 years. My muscles in legs an glute are so tight, but I get them loose with hours of work and water..yet to feel them get so tight I can't walk after 100 yards. My Drs are clueless and really don't give a dam..
2hr lecture in 2minutes! Thank you💞
How did it go ?
@@offthemapss lmfaoooo
So much info condensed in a digestible formulation! Thanks
That's call crystal clear explanation 🔥🔥
Keep in mind that acetylcholine do not enter in the sarcomere , it remains at neuromuscular junction or motor end plate.

Thank you for this video
Very, very helpful
I literally watched this video to prep for the upcoming Biology test tomorrow...
Same...
Same here
@@langrisvaude9298 Hiiii jungkook 😁
How are you?
Mine is in 45 minutes :)
Explained very well thank you very much now my concepts are clear
Glad it helped
Just helped me out for my exam . Amazing explanation 👍
Toughest concept made easy 😊 thank you 😇
So easy and well explained
I know right
Very helpful...
My assignment is done🙏
Extremely well explained and illustrated. Is there a complementary video for eccentric contraction?
Really really helpful. Clear cut visualization. Thanks alot. Stay blesséd💕
Who else revising the day before 🙏 🔥🔥🔥
Thank you very much to make a video on this vary topic..It was indeed very helpful ❤️
Actin is basically crowd-surfing on myosin. Thank you for explaining! I could not understand my professor's lecture at all.
Brilliant. Nature is brilliant. Wiser than whole humanity combined will ever be.
I swear by god this thing helped me more than anything else.
Shes really not Trynna catch her breath going hella fast🤦🏽♂️
Slow the video down
you can change playback speed
I'm viewing with 0.75x
0.75 speed is perfect
@@underherdomain1361sameeeeee perfect speed is 0.75
Veryy clearly explained..good✌️
R u a medical student?
Crystal clear explanation 👏
Smooth explaination.
satisfied😊
A long lesson withing few minutes 😍 Thank you so much❤️
Can you please explain slowly. because of This is fast for beginers 🤗

This is my 2 hour clss in almost 2 min.
So amazing my 2 hours lectures explain in 2 minute
im going to nail this exam
Nice explanation but little bit it is fast . Please slow your speed of explanation.
Otherwise it is the best one ✅
This video would be very good for revision
Thanks 😊 that lady is crystal clear 😊
I was always that ATP break before cross bridge formation or after crossbridge formation...now it's crystal clear..
Thank you😌😊

@@SaraAli-cg3qj so technically sliding filament actually occurs in sacromere right?

Great video, still super confused though im gonna have to watch a few times lol
Thank you so so so so much❤
This 2 minute video was a 3.5 hour lecture in the Army's ICU course.
Thanks you clear my confusion...
Oscar winning legend ❤❤❤❤❤❤
Very well understood....🙏🙏🙏
Thanks a lot for explanation.
thank you so much ❤️
Soooo clear!!
Interesting video
Thank you
धन्यवाद माऊली🙏
Thank you so much for this
thank you so much!
Thanks 👍
Brilliant amazing spectacular 🥰
Amen.
Very good explanation 🙂
Perfectly condensed love it
Thank you! It was the toughest one I have done but worth the effort. Wish I had time to do many more.
Nice yrr maja aagaya 👍
Nice lecture
Well explain
How does the myosin head pull the actin inwards? Is there some conformational change in a protein leading to shortening or something?
The myosin motor domain is what's doing the ATP hydrolysis. Myosin with no ATP bound is locked to the actin filament. ATP binds the myosin head, causes conformational change in both the head and lever arm, releasing the head from the filament and swinging it forward. ATP is hydrolyzed into ADP + Pi, which causes another conformational change in the head, increasing its affinity for actin, causing it to bind to the actin filament again, this time forward from where it was at the beginning. Pi is released, which causes the lever arm to return to its original position, pulling on the actin filament as it does so. ADP is then released, and another ATP binds the myosin head to release it and start the cycle over.
i now really understood thank you
Amazing
loved it
We talking about all types of muscle in the body or specific muscles, like heart muscle. Asking because Troponin is found in the muscles of the heart.
Great Video
0:58 wrong spelling, "acetylcholine", not "acetylecholine".
Sorry this vid was really slow; try 2x speed
Much better
good job
Thanks
Thank you for this
Which protein blocks the binding site on actin in a resting muscle?
Troponin c
0:53
Can someone explain this to Me
If we strap our hand to a machine which helps us move our hand move in and out and we let loose of it then how is it moving because we aren't sending neuro signals meaning the sites of bonding are still closed how is the muscle still contracting then??????
Finally!! Peace ✌
Bro.
This topic is fucked up LOL, by far the hardest 😅
Thank u sooo much 🥰🥰
2:00 Ca2+
Thank You! :)
Thank you!
Any personal training students here?😂🤣😂
😂
Yes 😂
Does magnesium have a role in this?
thank you sooo much
Is it ca2 plus or only ca plus
Ca 2+ not Ca +. Acetylcholine = uh see - tul or uh-see-tl. Named after the acetyl groups in Chemistry. Not ass-e-til. Excellent illustrations + a few corrections in the voiceover = perfect.

Better very little slowly......

Thnqq
Mam from where atp molecule bind to myosin during relaxation of muscle mam
ATPase (where ATP binding site is present) that is present on myosin head
Nice
wait a minute why he stood there like that
with those grippers out
put those dogs away
woof woof
Kon kon meenakshi mam k batane prr aya h yha 🥰
It's ca+2
Thank you! I peeped that and scrolled to see if anyone corrected her in the comments...
The myosin looks so cute
ACTUALLY i THINK you'll find it's Ca TWO PLUS, not Ca PLUS. i think lol
Vdo shown in Aakash institute 😅
I never get the atp part
Acetilcolina o calcio?
Good
👌👌💛
I don't understand a little bit.
Who all saw this video in 1.75 speed

That sounds horrible Chas. Hopefully the Drs will figure out a solution for you soon. Wishing you all the best, stay strong.
