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.

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

Such a clear and concise explanation. Thank you Dr.
woah. When you mentioned the bike chain analogy, it was like a fog cleared up in my brain. THANK YOUUUU
I am absolutely ripped right now and this was absolutely fascinating. good teacher.
This video is about to come in clutch for my A&P exam 🙏🏾
Thank you SO MUCH for making this so simple to understand.
Very short, simple and understandable. Thank you!
Your the best. Your channel is a gem. ❤️
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.
OBVIOUSLY AMAZING STACHE!!!;) Great explanation, thank you!!!;)
You deserve millions of views
having a test in less than 12 hours, you saved my grade and possibly my degree
Great explanation!
Simplest answer ever i looked.... Awesome... Thanks a lot.
My dog just died and became stiff within three hours. Came here to learn why. Thanks for the video. #ripshooter
A very simple way to explain rigor mortis..thanks Sir
Yaaas! The ‘stash is back!
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 👍🏼
Simplest and best explanation

Um thank you you just saved my life
Woww...that was really an amazing explanation

The mo' is back!
Alas, no. It's an old video :( maybe it will return soon ;D
Thanks for the great explanation
Short n precise !!! Wow
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.
Nice explaination
Marvelous explanation
Good information.
that was the most perfect answer thank you
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?
This was super helpful thank you
Thank you....please what about stone Heart phénomène !??
Beautifully explained
Thank you sir ,its clear my concept now
Thanks Sir !
thank you doctor this was very helpful 🤍🤍
Very well explained. Thank you :)
oh fantastic. thank you
Perfect explanation and stash?
Thank you Dr Mike!
How dead fish can move after death? Where it can get the ADP
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.
A bloody legend ♥️♥️♥️♥️♥️♥️
Can’t you get Rigor Mortis from a concussion not just after death?
easy to understand.thankyou.
Well discussed thank you ❤
Very nice 👌
thank you sooo much
Nice one Doc👍
good explanation for my exam tommorow
Fascinating. Thank you.
No touching on how it also needs oxygen? Since you are no longer breathing after death which builds up pyruvic acid?
woow thank u very much this is really helpful ❤️
crispy vid brother; appreciate u
Came for the knowledge, stayed for the look.
Thanks 👍🏾
How long does rigor mortis last for?
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
When I was a kid I tried to move my grandpa's arm in his casket like 2 or 3 days after he was dead he was still stiff af.. how?
