Bone remodeling and repair
HTML-код
- Опубликовано: 26 сен 2024
- What is bone remodeling and repair? Bone remodeling is when old, brittle bone tissue is removed or resorbed and gets replaced by new bone tissue. Remodeling also occurs when reshaping your bones after a fracture or when repairing micro-cracks which form during ordinary activities, especially when your bones are under stress, like after lifting heavy weights.

why this gave me more understanding than my college..i love it
Focused on lecture rather than Girls 😂😂😁
Willl my bone density will grow after quitting drugs? I am 23+.
Because you are fool 🤣
Bone remodeling in short:
-Osteoblast release M-CSF & RANKL → Convert monocytes into osteoclasts → ↓ Bone mass
-Osteoblast also release Osteoprotegerin (OPG) → OPG will inhibit RANKL → ↑ Bone mass
Finally understood the mechanism after 5 retake. love this type of resource, really insightful and articulate.
We're glad it helped, Dhruv! 🙏🏼
I've searched more than 1 hour for a video like this, thank you so much 😍 this sums up everything i want about bone tissue 👏
Hi Eva, Glad it was helpful!
Read your bible! (KJV, preferably) ♥
Great video. ties everything together nicely. Decided to review bony remodelling today and fascinating what you can pick up again on revision. Initially when learning about bony remodelling I never really thought about the significance of RANKL , but with drugs such as Prolia , a RANKL inhibitor , it becomes obvious as to why the fundamental understanding of the physiological processes is vital to clinical practice with associated pathological states such as Medication related oseteonecrosis of the jaws. Many thanks.
The illustrations are fabulous
I think there is a mistake at 2:41. Myeloid progenitor cells come from hematopoietic stem cells, not lymphoid stem cells.
Thanks for pointing this out! Our team will be reviewing this information and update the video as needed. 🙏🏻
Simple yet deep and well explained. Thanks a lot. Please make more animationlike this. I really appreciate it. Gbu all team!

Wow, this is really informative. Thank you! I lost 2 Parathyroids after a messed-up operation. Still don`t know how to deal with this, but trying and learning. 😰
Sorry to hear that. Katharina. We hope you're doing better now. 🙏🏼
Thank you for sharing. Please we would love to see more videos like this
That was exactly what was needed

Glad it was helpful! 💫 🥰 💖
Great visuals and wonderfully concise and explanatory! Thanks so much!
You're very welcome! Thanks for letting us know!
What a vivid way to present such hard topic. Thanks a lot !
Thanks for your wonderful comment! 🥰
Parathyroid gland stimulates osteoclasts (not osteoblasts) for bone resorption to occur. Small mistake at 5:05.
Thank you!!! It makes so much sense now!
Glad to help! 😊
One of the best video on bone remodeling
Wow, thanks for that feedback!
Very brief vidio......Thanks alot
Where's repair???
It starts at 4:20
Amazing. Now i remmeber the core of a complicated process in our body. TKs a lot
Glad to hear that, Minh! ❤️
Great video! Helped me a lot!
I'm gonna send this video to my professor 💀✌️
can you please make a video on the 2 types of bone ossification and the stages for each!!! I canot find any animations on youtube
Thanks for your recommendation! Our team will be taking this into consideration. Have a wonderful weekend! 💖
This is so good but i dont know english well so it was hard to understand😭😭 but tysm anyways that helped a lot🥹🫶
Dear Osmosa,,, please make a video about closed fracture.. thanks a lot.
Another great video by the Osmosis Team! Thank you!
Thank you too! 🙏🏼
My daughter had PAO surgery. The coverage is good no doubt. She still has pain and is very thin, could bone remodeling be an issue?
Does bone remodelling make the bone stronger and bigger like a muscle
What is the duration of this process
Very clear and straight forward
Thanks, Mary! 👍🏼
Are these cytokines that these cells use to signl or use as a communication to start og stop a process?
excellent job
Many thanks! ❤️
great vid
Thanks, Hanan! 😊
Medical college life is easier with osmosis! 💗💗
Glad to be of help! 😊
What do you think about bonesmashing?
why there is resorption in one side and the deposition in the other side not in the same side ?
When the bone is getting remodeled due to stress fracture , does it add 2-3 inches in height growth . When fully recovered
Well explained 👏👏👏, thank you so much 🙏
Glad you think so, Ramokunupi! 🥰❤️🙏🏼
I think there is a small mistake, yellow bone marrow does not produce blood cells as was indicated in the video. That is actually red bone marrow typically found in the epiphysis
Thank you so much for bringing this to our attention, Grant! I will be sure to pass this along to my colleagues on the Content Team so they can check the details with our Chief Medical Officer. 😊
how long is it ? how long the process go ?
Thanks Bro! this really helped me.
Thank you.....very usefull video
Welcome! 😊
Excellent presentation , but as far as I know osteoclasts doesn't produce COLLAGENASE , it is produced by osteoblasts actually , bone resorption by osteoclasts at it's clear zone (at ruffled borders) mediated by carbonic anhydrase , secondly it pump out hydrogen ions( after CO2 hydartion - H2CO3 formation - breakdown into Hydrogen and carbonate ions -then pump out hydrogen ions) which lowers pH , lysis of collagen in acidic media , which leads to bone resorption , Plz tell me if I m wrong
Thank you so much this is amazing
You're so welcome! 💖
Great explanation ma sha Allah!
Thank you. ❤
You're welcome 😊
Understand thanks. A lot
Happy to help 🙏🏼
excuse me but do you have a video explaining mechanism of healing of bone's fracture?
Great ❤❤❤❤❤🥳🥳
Thank you!
what if person diabetic? how will heal
I wish my actual lecture was that easy with less deatails :(
U ppl.arw.doing such a great teaching
..thanks a lottt
Hi Navyashree, thank you, we're glad you find our videos useful! :)
Thank u! ♡
Great, thank you.
How about left humerus? How many months it takes before healing?
❤️❤️.. plz make a video on osteoporosis
I have a question please regarding Wolff's Law: if we say that
Applied pressure results in bone resorption, while applied tension results in bone formation.
is that correct or not?
hi, could you add the bibliography used to make this video? it was so useful to me and i'd like to read sources too

This didn't really explain how the bones know what shape they're supposed to be. I am particularly interested to know why spinal stenosis doesn't reverse itself relieving pressure on the spinal cord.
Thank you very much
Really nice
Thank you! 🥰❤️🙏🏼
Great video, thank you
You're welcome, Euge! 🥰
the best explanation 😍
Thanks, Dunya! 💕
Excellent ... well done ...
Thank you, Mahu! 🙏🏼
I had 12 years ago a femure fracture very ugly caused by a tumore. I had surgery ofcourse the doctor said he clean everything there very good and he put me a metal plate wich I still have now and than I had the chimioterapy treatment. After 3 years I started to go slowly to gym and workout slowly but still even now after years I still cannot do the exercises for legs I did before the fracture because some pain during workout. You think the femur after this damage has healed properly? I will like your opinion also. Thank you
@5:03 I think you’re mistaken. Shouldn’t the osteoclast be reabsorbing bone to release calcium in the bone?
Hi Kevin! Thanks for pointing this out. We've notified our team about this so they can have the information reviewed. 😊
so why do women experiance terrible bone pain after menopause / hysterectomy/ ovaries removed,,this process stops estrogen production correct,where does the lack of estrogen fit into this equation,was it stimulating the parathyroid or what,????thanx for the great info,
My stupid bio teacher is making me learn this for a presentation tomorrow. Great vid if you have any clue what the stuff in it is. Does she think I’m majoring in orthopedics or something. No I’m just trying to understand transcription factors and how they affect bones. I’m screwed
Awesome
This is amazing
So...is bone death reversible?
Pretty helpful! Thanks!
thx! it help me a lot
You are a life saver ❤️
Always glad to help, Muhammad! 🥰

Glad you like it, Siti! 🙌🏼
Nice
Thanks! 😊
Amaaaaazing !!!!
🙌🏼 💕 ✨
Monocytes looks like a friendly thing 😊
Monocytes are the most badass myeloid cells
I would have loved to see more infromation about hormones and their influence on bone remodelling, such as the osteolytic effect of cortisol and such. An all-in-one video of what hormones affect bone remodelling.
holy shit that's so good
Does this process take place in the skull bones like the jaw or cheekbones?
Good question
amazing❤❤❤❤❤❤❤❤❤
Hello Sir, i had an small accident and 5th metacarpal was fractured, and it's just in position, doctor said, no need for k-wire , just split is enough for 6weeks. 2weeks back split is removed, now 2months completed, but fracture line still visible, how long it will take to go off fractured line on x-ray, and I'm afraid of do physiotherapy, because when I'm doing physiotherapy some pain on fracture site. Give me some suggestions, please, thanks in advance....
Same bhai mujhe foot m 5th metatarsal fracture hua h bs pair mudne ki wajah se maine bs Casting krayi hui h.....
Ab Aapki fracture line invisible ho gyi h X Ray se
Amazing !!!!
I was struggling with this topic in Harrison Internal Medicine...you made it a cakewalk.
PS- 9 days to go for my DNB Medicine finals😢
Best of luck, Mahmudul! You got this! 🤓🩺 🙌🏼

Why do osteoclasts eat the osteocytes?
Hello sir my 5th metacarpal was fractured (oblique fracture ), and it's just in position, doctor said just split is enough for 6weeks. 15days back split is removed, now 2months and 10days completed, but fracture lines still visible, how long it will take to go off fracture lines on x-ray, metacarpal fractured lines still visible after 2months??? how long it will take to disappear fractured lines on X-ray.. can I do physiotherapy because, fractured lines are still visible now. please tell me, thanks in advance....
