- Endochondral ossification is the primary method for bone formation in the body. This video covers the process in a step-by-step method to help you understand exactly what is happening.
Video Number- Anatomy 1 -11
Why do professors and authors refuse to teach like this? In a way I can understand. Thank you, thank you, thank you!
So the primary ossification center of endochondral ossification was an intramembranous ossification center in the beginning, then turned to endochondral production after the gap formed by nutrients deficiency?
I also tried to access your website, however, it seems to be 'unavailable', will it be up and running soon?
Sou Keng Leng Hi Sou, yes the website will be back up and running very soon, however at the moment TH-cam has the majority of my lessons :). I will get back to the videos as soon as possible, just had to take a little bit of time off for a surgery. If you ever need any specific help, feel free to email me directly at asher.kidd@gmail.com Good luck with you studies!
i am better than i was 13min ago. thankyou
I am better than I was 6.5 minutes ago [watched on 2x speed]. thank you.
first of all, your drawings are cute! i've looked through enough of explaining of how ossification process forms bones, yet most of them just confuse me with tons of words that i still struggle to remember. love how you explain everything so clearly. keep it up!!
七七宝 You're very welcome, thanks for your feedback :)
OMG NOW I GET WHAT THAT OSTEOBLASTS DOES AND WHERE IT IS COMING FROM! THANK YOU SO MUCH I CANT THANK YOU ENOUGH.
You're the reason that I'm gonna pass my exam tomorrow. You rock! Thank you for dispensing that knowledge in a way that even I can understand.
did you pass?
@@daisyruiz6194 can't remember this exam but i finished the semester with a 4.0! videos like these no doubt saved my life.
@@DavidLee-jp6sd wow thats so great. I’m struggling so bad tanking my gpa at 2.5
I love your handwriting and your accent!
Why would the osteoblasts create spongy bone just so it can be degenerated by osteoclasts in the next step later?
As I have commented before your videos are the best...easy to watch over a few times without the slapstick humor in other videos...your handwriting is perfect 👌
online med school has been hard, this just made my life easier! thank you
Great video! Any chance you can turn on closed captioning ?
Firstly, thank you! This video is really helpful.
I just wanted to know at which point the periosteum appears, and how it does so? Something to do with Perichondrium?
Now I can completely understand all the process of endochondral ossification.. Thank you soo much
Hi Asher!
I'm currently taking a anatomy& physiology course over the summer and I find your videos to be very helpful. Please continue making these videos and educating students about the human body!:D
I am still 1st year
Feelz upset 😡
Still 5 years up to go for me
@@amrali1801 same
Your videos are so helpful ! thank you so much (from a French medical student ;) )
Thank you very much that was very good🙏
Really useful during quarantine. Thank you.
To me it seems as though step 1 is moreso describing subperiosteal ossification as opposed to the internal endochondral ossification, anyone else agree? I'm having a hard time differentiating the two and this seemed to make that complication a bit worse for me - nonetheless, a very helpful video!
Hello, great video! You help me a lot
Could you add subtitles please
You did an amazing job explaining this. You've helped more than you can imagine with studying from my textbook. Keep up the work you do 🙏
Thank you !Thank you !Thank you !

Question: you wrote in the second picture that osteoclasts degrade cartilage matrix. I though osteoclasts only degrade bone matrix?
Please upload more videos...
thank you very much indeed!
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 crack 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....
Nicely done. However, a minor correction - your sesamoid bones (such as your paired patellae) do not form via endochondral ossification. They form by intramembranous ossification.
Waooo,,, like it
Is this an Australian or a British accent
which device/ software did you use to draw and record this? I am looking for an efficient digital way to store notes
Damn thanx for ur fucking good video
I thought cartilage was a vascular.
In order for blood vessels to be present there needs to be channels?
Mature cartilage is avascular, correct :). But as with any building process in the body, temporary vascularisation helps with delivery of essential components. Once the whole process is complete, the only component of the bone that has direct nerve and vascular tissue is the bone itself.
Awesome explanation!! Love your vids, thanks for posting.
fantastic video! I learned & got engaged more in 13 minutes than I have been for the last 2-3 weeks. Thank you!
Once the chondrocytes start dying, you've mentioned that a central "clearing" begins to appear as the calcified matrix begins to deteriorate. Does all of the matrix get disintegrated? Or parts of the calcified matrix are retained and provide a scaffolding to the osteoblasts to secrete osteoid? Please help.
Hi Neely, you can think of the osteoblasts following the cartilage border as it deteriorates. This central clearing is what will become the medullary cavity, this is where we house yellow bone marrow, no osteoid type cells are there at all in the much later stages. I hope this answers your question, all the best!
It's an Amazing Video !! Thanks A Zillion Sir!✨
Thank you so much . Helped me a lottttttttttttttttt.....u are too good
I feel like he said last step like 20 times.
your videos are incredibly useful. Thanks very much for sharing them.
Great tutorial, I appreciate the clear and precise way it was taught-- you are a natural. Thank you!
grounding123 Happy to help :)
your videos play important rule in my course ,thanks
7:18 why do osteoclasts resorb the cartilage and not chondroclasts? I dont understand 🙁
Hi. You mentoned that endochondral ossification occurs for all bones below the skull with the exception of the clavicle. But what about the ribs, scapula and bones of the pelvis?
those are just flat bones. I don't think they undergo this process.
Tonmoy Khan they undergo intramembraneous ossification
Ribs and bones of pelvis by endochondral ossification, not sure abt scapula
They undgo In intramembranous ossification
Thank you for this great video! Very helpful and you explained it very well. Thank you 1/8/2018 :D
what is central clearing ?
Thank you! I feel much better about answering test questions about this tomorrow!
Pleasd tell me sir.... At what age this growth stops
25 maybe
do scapula and sternum also undergo endochondral ossification? I thought they were flat bones.
The scapula undergoes intramembranous ossification and the sternum undergoes endochondral.
I think sternum also undergoes intramembranous ossification
Very good video. Thanks!
Hi. Do you have the reference list?
How do the enlarging chondrocytes signal the surrounding cartilage to calcify? I thought you had to have osteogenic cells for that to happen.
+leapofthefrog Hi there, I believe you may have calcification confused with ossification?, which part of the video are you referring to. I'll have a quick look and try help out.
+Medic Tutorials It's at about 3:57.
+leapofthefrog Ah yes I see where you're at :). It's definitely the chondrocytes that secrete in this phase. They are not sending a groth message as such, just releasing intracellular components that cause matrix hardening and subsequent chondrocyte death due to lack of nutrients. You can think of it as an extremely tightly regulated form of controlled cell death.
+Medic Tutorials growth* derp :p
Ah, thanks.
your saving my collective ass! literally
i wish the diagram was bigger, damn.
I was wondering whether the scapula is an intramemberanous ossification or endochondral ?
Most bones of the body develop through endochondral ossification including the scapula, vertebrae , ribs, sternum, pelvic girdle, and bones of limbs.
scapula undergo intramembranous ossification, because scapula is a flat bones. other example of flat bones is ribs.you should see another of the his vid tittle intramembranous ossification
the intro song is absolute garbage, I thought it was bad because I sped it up but damn even on normal speed its bad, I love the video though!!
Unfortunately, ya can't win 'em all. I am really glad to hear that the video was useful for you though!
is it the chondrocytes that die after the calcification of the matrix at 4.45
+MrDonIlyas yes
WAH BETAV.WAH TUM TOU BARAY HEAVY DRIVER HOON ......
3 Stages of endochondral ossification?
thanks alot
thank you ❤❤❤❤
Why don't you upload more videos?
Does it increase bone length or width?
N what is formed during each stage ?
do anyone have transcript for this video ?
This was Sooo helpful! Thank you so much!
What about the sternum and the scapula?
U write fast r u using Apple Pencil
Thanks very much.
A question: Ossification takes place before flesh development?
i came from blg guys
Good video, but basically just a reiteration of Marieb. Nevertheless, thanks for uploading!
thank you sooo much for your effort in making this video, it was incredibly helpful.
Ossification enchondrale ❤

Where do the chondrocytes come from?
thank you so much. I am going to watch all your videos. please make more
Thanks again bro
Thank you!
This is great thank you :)
How the periosteal bud formed???
That was massively helpful and I really appreciate the visual aspect with clear explanations and colours, thankyou 😆
Iam stupid i dont get it
Please make a video on mechanism of cytotoxic t-cells
Thank you Sir
