As a Nursing Student, I can't express enough how much I appreciated this video!! This is such a clear and precise explanation on the subjects. Wasn't ready for you to say skeletal though, wasn't expecting that accent to change the pronunciation like that. Definitely a new subscriber to the channel!
Oh dear , thank you so much for making me understand this after 30 years , second I love your moustaches very much , you are so nice teacher and so good looking like a price
One point here...isnt it technically ADP + P that causes it to bind, and ATP that will cause the release? Because theoretically, if it was just ATP all the way around, there would be an equal chance that the ATP stores would end during the point of detachment, but since ATP is only involved in the release, when its stores are depleted, there will be none left to cause the release, resulting in rigor mortis.
@@satrah101 from my physiology book "Note that each thick filament of roughly 300 myosin molecules has multiple myosin heads, and many cross-bridges form and break continuously during muscle contraction. Multiply this by all of the sarcomeres in one myofibril, all the myofibrils in one muscle fiber, and all of the muscle fibers in one skeletal muscle, and you can understand why so much energy (ATP) is needed to keep skeletal muscles working. In fact, it is the loss of ATP that results in the rigor mortis observed soon after someone dies. With no further ATP production possible, there is no ATP available for myosin heads to detach from the actin-binding sites, so the cross-bridges stay in place, causing the rigidity in the skeletal muscles."
Woooowe very detailed but yet simple explanation. Where have you been when I was in college?🤣Im a Physical therapist and already looking forward to your next videos
Do people's fingers go into a claw grip when they die? I've never thought about it before. The natural position for fingers that are tense is bent, so it should follow that rigor mortis comes with fingers in a claw position.
Would then very elderly women with major calcium deficiency not exhibit little rigor mortis effect? What about body parts that were separated at death through an explosion or crash impact I thought ATP would vanish within seconds very few minutes after death?
Thank you, i'm form Brazil, i could understand because you spoke slowly ... I search for this explanation in portuguese but it wans't able. The nature state os muscle is contract, so to be relaxad we spend some energy, that's the reason when you win muscle mass you spend more calories
This was the simplest answer I’ve been looking for. Thank you for keeping it simple.
The first simple and clear explanation that I came across thank you
Thanks a lot for such a lucid explanation
Nice it takes just 3 minutes to be aware about all the subject without miss any informations thanks matt.

Glass of water, sir?
No one explain it like you even the great TED ED!
LITERALLY A LEGEND
I am absolutely ripped right now and this was absolutely fascinating. good teacher.
Best explanation I've seen thus far! You covered all important components without overcomplicating it! Thank you!!!!
Such a clear and concise explanation. Thank you Dr.
What a lovely explanation, I wish all teachers teach this way, so easy to understand and very short lesson too, straight to the point kudos ❤

Hi , 96 comments and you are the only one pointing this out. Hope med students at not using this video, we are all doomed.

You mean, attachment right? Not detachment
woah. When you mentioned the bike chain analogy, it was like a fog cleared up in my brain. THANK YOUUUU
This video is about to come in clutch for my A&P exam 🙏🏾
Thank you SO MUCH for making this so simple to understand.
Simple and clear, am subscribing for my medical Physiology class now!
OBVIOUSLY AMAZING STACHE!!!;) Great explanation, thank you!!!;)
Very short, simple and understandable. Thank you!
I've been listening to your podcasts on anatomy/physio and I had no idea you had youtube videos too. I've been missing out.
Your teaching skills is very nice I am from India
Your the best. Your channel is a gem. ❤️
You deserve millions of views
My dog just died and became stiff within three hours. Came here to learn why. Thanks for the video. #ripshooter
Great explanation!
A very simple way to explain rigor mortis..thanks Sir
having a test in less than 12 hours, you saved my grade and possibly my degree
Simplest answer ever i looked.... Awesome... Thanks a lot.
amazing simple and easy to learn you teach better than any biology teacher i have ever seen in my life XD. also i love that mario moustache
Please continue to make more videos… you are really good 👍🏼
This is amazing wow... Short and so precise just wow thank you so much
Woooowe very detailed but yet simple explanation. Where have you been when I was in college?🤣Im a Physical therapist and already looking forward to your next videos
Thank you! Straight to the point explanation.
Simplest and best explanation
Thank you so much.
It was very helpful for my studies.
Yaaas! The ‘stash is back!
A simple explanation that answer all of my question
very informative and easy to understand
It's very very easy to understand. I love it!
You just made life a lot more easier.
Love from India... I have my Forensic medicine examination in a few days
Couldn't have been better. Thank you.
Very simple basic explaination 💯👍🏼
Thank You😀
Thank you bro ,
love love ❤️💙🧡 from INDIA
Awesome! I've always wondered how that worked. Thank you!
Thankkk youu so much, this really helped me out in my work!!
This was a good brief explanation that I came across.

Omg thank youuuuuuuu . This was the best explanation
Thank you for your explanation. Great video!
Woww...that was really an amazing explanation
the explanation is so clear
Um thank you you just saved my life
Thanks for this! So helpful in Biology 1. 👍🏾
Thank you very much for keeping it very simple
Very informative and simple thank you !
the best explanation
Simple and straight forward .
it is a complete and brief explanation of RM.
but Dr. what initiates the relaxation process after 24 hour?????????
good explanation for my exam tommorow
Thanks you for making this simple and brief 💞
SO WELL EXPLAINED!!! thanks!!
Such a good teacher
This was super helpful thank you
Thanks so much,, well explained 👍👍👏👏👏
Thank you sir ,its clear my concept now

Alas, no. It's an old video :( maybe it will return soon ;D
Thanks for the great explanation
that was the most perfect answer thank you
Wonderful explanation like all of your videos! Thank you!
There's so many of these fibers probably trillions. There's going to be plenty in the contracted phase.
Short n precise !!! Wow
Beautifully explained
Marvelous explanation
Nice explaination
Came for the knowledge, stayed for the look.
Perfect explanation and stash?

crispy vid brother; appreciate u
Good information.
Would then very elderly women with major calcium deficiency not exhibit little rigor mortis effect? What about body parts that were separated at death through an explosion or crash impact I thought ATP would vanish within seconds very few minutes after death?
Nice one Doc👍
I don't want this to happen again. How do I stop it? To say it's scary is an understatement.
Not only is hot, but he's smart! Thank you for the video, we are doing a project on this in my anatomy and physiology class. :)
Is it contagious ???
Haha
THANK YOU THANK YOU THANK YOU
thank you doctor this was very helpful 🤍🤍
woow thank u very much this is really helpful ❤️
Well discussed thank you ❤
Does blood come out from all the orifices of the body just after death? If the heart stops that is what should essentially happen right?
No, just the circulation of it will stop. The blood is still in the body.
does it happen when you try to get back the body part back has broken?
Very simple and best
Thank you....please what about stone Heart phénomène !??
thank youuu sooo muchh!!!! i understand it even more now :))
Thank you Dr Mike!
How dead fish can move after death? Where it can get the ADP
easy to understand.thankyou.
Very nice 👌
Bro is flexible his skills with his muscles
Can’t you get Rigor Mortis from a concussion not just after death?
Thank you, i'm form Brazil, i could understand because you spoke slowly ... I search for this explanation in portuguese but it wans't able. The nature state os muscle is contract, so to be relaxad we spend some energy, that's the reason when you win muscle mass you spend more calories
Thank you!! I finally understand!
