Also cartilage. It has extremely limited, but in most cases absent, blood supply
Half of Your heart replaces itself I think every year
Tendons have something similar
Me with broken cartilage in my knees that literally need surgery 😢
I said that too!
Actually, the brain doesn't regenerate either. When someone has brain damage, if they are able to recover in some way it's because another part of the brain takes over that function. The damaged part never regenerates.
@MJafro States it's false information - refuses to elaborate
I swear CS-tv shorts are dumbing down the world at an exponential rate.
How come? I don't understand. Did the creator say something wrong?
I guessed brain, thought I was dumb
@Clap Chowteeth aren't part of endoskeleton.

Other than the spinal cord nerve regenerate/replace those damaged.
You can listen to brain-dead conversations. Nice
He was pretty much on the spot with the ear. Certain issues with the ear can heal/ be healed. But hearing loss is generally irreversible
Teeth can actually heal themselves, it's called remineralization.
Was looking for this comment
My mother has osteoporosis and she's been able to save her teeth and reduce skeletal pain by drinking nettle and green clay smoothies. The taste is vile, but it works.
Factor x from the rat fish liver oil! Lol
There are literally SO MANY body parts that can't heal as explained by so many in the comments here. Here's another example: your spinal discs. Once they rupture, you either deal with permanent back pain and loss of mobility or get surgery to remove it entirely so you stop leaking all over your central nerves (massively painful) and still deal with permanent back pain and loss of mobility.
That's actually untrue! In some cases, discs cannot be repaired, but in most cases they actually can heal and the nucleus (gel-like substance inside the disc) can be reabsorbed. It depends on many factors.
False!!! This is absolutely false. 66% of disc herniations and 98% of disc sequestrations heal spontaneously within 6-12 months! Happy to cite research, this is amazing stuff.
Bruh "herniations" is so wide and vague. There are slipped, ruptured, bulging, etc types of herniations. If you guys seriously think a disc that was fully ruptured can be healed, try again. The pain fades over time, but it never goes back to original condition like magic
@Daniel Song Respectfully, you obviously have no medical training. I’m a doctor and low back pain is my specialty. A “slipped” disc is not even a real thing. For the record, the types of disc injuries include but are not limited to: annular tears, bulges, herniations, extrusions, protrusions, and sequestrations. Now for the research; please read this peer reviewed article showing that 66% of disc herniations resorb spontaneously given time: pubmed.ncbi.nlm.nih.gov/28072796/ I can share tons of other papers.
“big words. make me seem smart.” Truer words have never been spoken
Fun medical fact: your teeth are NOT part of your skeleton. Teeth are made of different stuff than bones, and they also grow differently.
They're not bones but definitely are a part of the human skeleton So in the words of sam 'o 'nella "And to all those who think teeth arent part of your skeleton, eat shit and die"
Specialized osteocytes or whatever
@Verticom ameloblast, osteoblast and cementoblast make the 4 tissues of nipple nibblers🦷
No one is gonna say the outside is made of enamel?
I chipped my tooth today but now I’m watching this fricking video after I wait for it to heal.
Your eyes actually have amazing recovery and healing
Not the cornea part .
No if i stab myself in the eye im blind
If you ever feel useless, remember these guys exist.
Your eye is also technically correct. My first guess was nervous system, once a nerve cell gets damaged it’s done for
Bro got his human anatomy degree from the mcdonalds drive through
I think the nephrons in the kidneys can't heal itself.
@Xaralampos Xapsas nails grow back
@Chain drunkards spine I guess cause neurons can't regenerate
@Kendrick Crawford Jr but they don't regenerate I to a new nail from the location of the damage. Nails growth is at the base of the nail if you cut off the top of your nail that part is gone forever, it doesn't heal itself but instead grows a new nail.
Teeth don’t grow back Toddler has entered the chat….
ahem achktually they dont, those are different sets of teeth 🤓
@kb90xMSM for 6 months to 1 year helps repair and regenerate ligaments, tendons, cartilage and TEETH.
i don’t claim the bad energy on this video 🧿🧿🧿
quite a few parts actually not just teeth, there's also the lungs, kidneys. General rule is if you have more that one of them, damage is permanent.
Your lungs and kidneys can heal so can everything else besides your teeth
@Aureus From my understanding and from what I have read lungs can't heal like the damage from smoking won't heal or if you are caught in a fire and inhale heated smoke and all that it won't heal to 100% or close to it will be damaged forever. And with heal I mean like the liver that can be abused like hell and basically heal to 100%. But if they mean heal as in it can do something to better than teeth sounds right.
Actually teeth can heal only if you were a lil kid
@sebulbathxno, science actually says that if a smoker goes 2 years without smoking the lungs will be back to completely normal
"Big words......make me seem smart."
Bro summoned a whole fandom by saying the word *'endoskeleton'*
The two cells in your body that can't regenerate themselves are nerve and cardiac tissue. They will turn into scar tissue instead.
Scar tissue is repairing... If your nerve tissue didn't repair you would soon be history
Nervous tissue does actually regenerate and while cardiac tissue regrowth is very limited, it's been demonstrated you still have a few stem cells flying about that can develop into it.
Nerve tissue does regenerate but interneurons take like 50 years to regenerate
Let’s pretend that we have a podcast but instead let’s just talk to each other for these clips
As a person who just came back from the dentist, my immediate reaction was teeth 😂
There are actually three, generally speaking nerves, cardiac tissue, and skeletal muscle. - Medical student
Nuh uh , skeletal muscle can heal up to an extent . They always undergo micro tears and heal up , basically hypertrophy response to physical agent ( tension ) .
They do have a limited regenerability, through the presence of the satellite cells. They can divide to become more satellite cells and then differentiate into new striated muscle cells. Although as mentioned, they tend to regenerate via hypertrophy rather than hyperplasia.
@Sravan S well all of these can “heal” through fibrosis and hypertrophy (for skelly and cardiac). I’m operating under the idea that healing is regenerative- not compensatory.
@Neto ya exactly. Hyperplasia vs hypertrophy is the caveat.
Some nerves can regrow (fila olfactoria)
there are 3 types of cells: labile, stable and permanent. Labile and stable can grow themselves back, permanent cannot
Fun fact: it heals when you’re a kid
This bro got his anatomy lessons from a shellfish under the sea
The brain/nervous system... once damaged, it's always damaged

Teeth are not apart of an endoskeleton.... in order to be apart of an endoskeleton due to the lack of collogen you have to be able to heal.
Nice Google search.
@9ine God google searches save lives
@9ine Godthis is common knowledge
@Alex stekcub No it’s not💀
The only body part that cannot heal itself is the heart, everything else will be fine
Actually you can heal all parts of your body. It is called Separation. That is when you put yourself in a state of deep sleep and have a recording of a certain sound wave with the words heal the body the brain would heal the entire body even give you arms if you were missing them.
I love this comment not too many people know the power of healing tones and frequencies
You need calcium, magnesium, phosphate, zinc, and a tiny bit of fluoride for your teeth to maintain and rebuild themselves from minor damage👍
Minus the Floride its corrosive and serves no purpose
@jayhawk184 besides the remarkable resistance to cavitation and carries?
@Sean Gannon false
@Sean Gannon if flouride prevents the damage and flouride is in the water, why do we still need to bursh our teeth?
Actually stem cell replacement has regrown teeth. In a few years we’ll be able to grow our own missing teeth back! I’m sure there’s a link on CS-tv..!
I like how this guy hit you with a common sense question like it was some exclusive shit only he knew
I was told by my dentist that your teeth can actually heal themselves on a very slow/long-term level. Obviously not chips (that's like lobbing a finger off). But on a microscopic level your teeth can get better over time in terms of enamel, roots etc. Just not once you get damage past a certain point. At least not in an amount of time that you'd be willing to wait for. But basically he said that your teeth can heal/improve in health over time in a really clean environment. I haven't looked further into it, but I did think this was super interesting.
I lost a crown once and it left a hole in the middle but the hole actually filled back in . still had no crown but it made it repairable with a artificial crown.
I heard that chewing xylitol gum throughout the day (at least 5 grams of xylitol a day) can remineralize your teeth.
I got something meant to encourage the process that you apply to teeth. I've heard dentists sometimes prescribe it for very minor cavities. But this is just what I've foubd from very brief research. As best I can tell, it has helped make my tooth pain go away entirely. Haven't been to a dentist several years so I dont have xray evidence they healed.
There was a video of an Ohio dentist who saw how third world folks had their teeth remineralize...D3,K2 and Vit A phenomenon.
You right the video is WRONG

Hair technically doesn't grow BACK, but it does grow longer. (Because hair grows from the roots, not at the ends)
Weak spots in the enamel can recalcify. It's once it gets into the dentine, then it becomes a problem.
heart and brain leaved the chat.
Technically actually they can grow back with assistance in stem cell therapy. It's currently in trials but they essentially inject stem cells into the lost enamel and will grow back
True, also there is that Japanese toothpaste that contains the stem cell treatment.
Godspeed. I really want this to happen
@kylethedaleki been trying to find this tooth paste but cant find anything about it. Do you have any more information about it?
@Uhreg I can’t remember the name sorry, I do remember there was two types. The original version worked but made your teeth yellow. So the second version stops that. It might not be Stem cell, maybe more of a remineralisation process.
Doesn’t this research strangely not get enough attention? Or funding? Last I heard of it was from a family guy clip and Peter goes “WHY ARENT WE FUNDING THIS???” and I still don’t know.

Not everyone should start a podcast 💀💀💀
My left eardrum got infected & I eventually lost my hearing I knew my eardrum was ruptured but never went to the Dr.... I took about 6months but I got my hearing back in my left ear, amazing I never knew it would heal itself without any medical attention. Human bodies are a miracle in itself.
I thought that if it's ruined then i wouldn't have the ability to hear again. So it can heal and function? Thank god
U just don't clean your ears bro
Glad everything is ok :D
@You it's fixable, but if left untreated, kiss your hearing goodbye.
@木 i was shocked that morning my right ear sound like my eardrum had losen. Realized it's a huge plug in there that took me hours to get that out
The heart cannot repair itself either.
Me, a dental hygienist: YOUR BRAIN
Nerves don't regenerate, if you lose them, they are lost. Our body is not designed to reproduce nerves.
Yes exactly, I can confirm this, as after surgery where the nerves have been cut, I've lost sensation in that area, & it hasn't re-connected or re-grown new nerves.
@Chucklevision where on the body and how long has it been
"big words make me seem smart"...this is how ive gotten through life so far
The stereocilia, the hair cells within your ear. If these are damaged, they won't heal back up.
Eyes, it's eyes. You can't regain your vision or just regrow your eyes can you?
So you're telling me that human's eyeballs can regenerate?
if only we were in the one piece universe where we can just drink milk and our teeth grow back like its nothing
I wish I'm missing my top set of teeth entirely
No lol that's clearly Luffy's devil fruit ability oda give us a hint already
So nails can now heal themselves?
My dog ran full speed and jumped at me one time when I got home and hit my chin so freakin hard. I got a nice little divot now thanks to her. Can confirm it doesn’t grow back lol
"Doesn't grow back" *names the fastest healing thing, your eyeball* 😂
It's your tongue actually.
Didnt know eyeballs heal
I scratched my eyeball once and the brown ish, Idk the term for it but it’s brown, remains there
@Maruk C Ive gotten ash under contacts, scratched my eye a bunch of times. Pain only ever lasted 6-18hrs
I was once beaten up by security guards,my left eye became bloodred and also crooseyed,I thought after it healed it would leave a brownish substance but it didn't and it returned to its normal position.The whole healing process took about 2 months
Nerve left the chat
Actually my Teeth have Chipped and grow back unnoticeably quick. I have lost Chunks from my bottom teeth and I just brush regularly but not too often, and they fill right back in
Your scaphoid is a bone in your wrist that will also not heal itself. It has very little blood supply(I believe only one major source) causing fragments that have broken off to die (since they have no blood). The only way to fix the fracture is with emergency surgery.
I was about to say this. Broke mine last year and had to have surgery to get a screw in it.
The labrum can’t heal itself
Unless you get is sowed back together with surgery
Actually scaphoid has two arteries supplying it. They can either enter from the same side or from different sides. If the arteries enter from same side then during the fracture the whole supply to the bone gets cut off and it won't heal but if it has supply from different sides then it will heal
Scaphoids can heal without Sx
I believe the heart is a viable answer. It may patch itself up but it's just scar tissue it is non-functional other than the purpose of patching the damage.
no way chipping your tooth doesn’t grow back holy moly
"Big words. Make me seem smart." Oh buddy, that ship has sailed.
Your brain, the hair cells in your ear, there are lots of things that can’t heal once damaged.
An infant had a fingertip cut off. Doctors did not seal the end of the finger, but kept it clean and allowed to heal. The fingertip grew back. Studies show the body loses this regenerative ability at about 2 yrs old.
I’ve had a chipped tooth when I was a kid, and it sealed itself. You can definitely heal your teeth. It just isn’t acknowledged by the dental industry, likely because there isn’t a medically recognized way to produce high efficacy healing. It is possible, though. People have done it.
Minute damage to teeth can be "remineralized", which is definitely acknowledged by the dental industry. But the amount of damage that it can happen with is miniscule and it technically isn't the tooth "healing itself" so much as the minerals in your mouth just... depositing over time.
And if you can heal yourself, why would you need dentists? Same goes with the medical model of the west. Mask the problem with pills and you have a customer for life, actually find out what’s wrong and teach them to heal and prevent… Big pharma would cease to exist.
"Big Words make me seem smart" Me who is German: I am Megamind!
There are plenty if things that either wont heal or grow back. Pretty much anything that doesnt have bloodflow or has minimal amount of it. Scaphoid, Central Nervous System, Parts of the meniscus, ACL, PCL, etc. Even your Peripheral nervous system doesnt regenerate in certain regions. If they do regenerate, it takes a long time.
AcShUaLlY... there are several tissues that can't "heal" or "grow back" in the sense that once they are damaged, they lose the original function/properties: neurons (grey matter and retina), teeth, cartilage, cornea, lens, cardiac muscle, lung tissue, kidney tissue... It might be more, those are the ones that come to my mind rn.
The retina has entered the chat
Central nervous system :am i a joke to you
I did not need to see this after me chipping my tooth Yesterday😢
Just a chipped tooth, nothing crazy. Could’ve lost a tooth after all🤷♂️
me who has both lost a full tooth and chipped the one next to it😅
@arv how did you fix the chipped one?
@kirihara the dentist fix them I had chipped teeth broke again gotta get it fixed again lol
@602Pyr0 *How much was it. And are they completely fixed?*
Heart cells don’t divide, so the heart can’t get most types of cancer- but blood will probably still try to clot up a hole in it. Idk how well that’d work with the pressure, though.
I know they say they heal over time. But I have yet to see anyone with an annular tear of a spinal disc heal itself. They end up popping pain pills, doing physical therapy, resting and eventually just say fuq it and live with the pain or have surgery. Some may have pain relief temporarily from the pills, therapy and rest but the pain comes back bcuz the tear can not heal itself. The only way to heal an annular tear is by injecting Fibrin into the disc.
You can trigger the gene expression to fire again and regrow a replica of your adult tooth that was lost. Things they don’t want you to know.
True!! It happened to me when i was young… on the second row if teeth… grew back the way it was before. I stil have the same tooth .. you never know was broken in half … I remember spitting the bites out of my mouth 😅
I dont think there's a singular gene linked to tooth development. Most likely it's a set of loci that are expressed to promote bone growth of the jaw since you are born with your baby and adult teeth built in. Even if you could somehow cause osteogenesis, where would they be? You don't have any free space for them to develop in.
How do you trigger this?
Lol, make it happen!
I thought he was talking about the certain nerves that don’t heal 😂
These dudes have no clue what they’re talking about 😂
For those of you that don’t know, these guys are gen z.
Gen Z -"You guys, like don't cut your arm off, it is one of the things that wont grow back." Followed by a read from wikipedia 😂🤣😂
TRUE ..but you can Super Glue that broken piece back..I did that & ten years later my dentist replaced that tooth..
This has nothing to do with the skeleton though. Unlike teeth, bones are extremely regenerative. The difference is that teeth aren't actually alive, it's all dead material produced by cells in your gums (very oversimplified). The only way to regenerate teeth is by replacing them ( like sharks and crocodiles do) or by adding new material at the bottom (like rodents do), this would be similar to how your fingernails and hair grow. Also other body parts like the central nervous system don't regenerate either, that's why spinal cord injuries are so terrible.
After watching this, I am so happy to know that I’m not the dumb one in the class.
Bro made him explain the simplest question 🤣
Arm gets cut off. Can’t heal back. Him: YoUrE nOt uNderStANdInG ThE qUesTiOn
The tongue doesnt heal back trust me. When i was a kid some things happened leading to me getting broken glass in my mouth and sliced my tongue and went threw to the other side. Truthfully i don't understand how im still living considering i was not only constantly losing blood but i was also drowing in my own blood. True story btw. Fun fact i can put my finger or other objects threw my tongue now😅
Bro thought endoskeleton was a big word 💀
The ribs can grow back too, if properly surgically removed.
Yeah but if you get pits in your teeth you can actually grow enamel back over them if you follow a specific regimen. I’ve seen it happen.
Always seemed like a major floor in our bodies that our teeth don’t grow back
people are supposed to die much earlier, tooth is not a big deal back in the day.
@DesertSessions93 yer, may have spelt the word wrong.
Brain has left the chat crying
my uncle's teeth grew back after he stopped wearing his dentures. he was in the hospital after he had a heart attack.
Another thing is the acl. Just recently tore mine and had to get surgery
Yeah, I guess anything that can snap, won't grow back, at least not without setting it straight.
Tendons and ligaments have very little blood supply, but will eventually heal to some degree. The degree being basically 0, and "healing" meaning retaining some functionality
Your acl can heal on its own if it isn’t completely torn. It’ll just take way longer
@Grimm Creeper thats not true as a person with two torn acls. It's just that if you partially tear it you can still function normally to a degree.
@Grimm Creeper like wayyyy longer years and years
Your teeth can heal itself. You can remineralize teeth and heal cavities. I’ve done it.
Your heart cannot regenerate dead cells.
A liver can regrow itself that is why some people donate half a liver and the half you donated gets put into another human and it regrows to a fully working liver
That’s crazy if this is true
SO I CNA BE AN ALCOHOLIC?! :DDD
True, but the remaining liver must be healthy.
@Else worth it's true, I wish all parts had regeneration like that
"Kinda like a bone"............ TEETH ARE A BONE
The heart doesn’t heal itself it just scars up
Dentist, the only doctor that doesn't fix anything
Teeth also do heal itself. The capability reduces as you grow older.
Its the vaccines is the reason that is the case.
@THE KILLER SENTRA yes of course. The vaccines cause you to age💀
Him: “ Endoskeleton “ Me: “..FNAF-“
Aight who else said "The Ding dong"... I can't be the only one💀😭
He was almost right with the ear answer. The hair cells in your inner ear that convert vibration into what your brain perceives as sound also can’t regenerate. Being deaf in one ear has taught me a thing or two about hearing loss.
Im not listening to someone who can barely listen.
Liver left the chat
literally what happens in this show bro
Many people don’t know this, but nerves do heal, just at a slow rate of about an inch per month. They only don’t grow back if it’s a severe brain type injury
"an inch a month" what the hell are you on about lol
Care to elaborate?
@Wise Crow they grow back if the tissue is still there. However if you cut the nerve, for example one of your spinal nerves, it heals with scar tissue that doesn’t work as well. Correct me if I’m wrong
@Muppet S I think peripheral nerves heal differently than CNS nerves. The CNS ones (brain, spinal cord) don't grow back at all so far as I know while peripheral nerves can (otherwise skin grafts would have no sensation). I think major nerves in your limbs count as CNS, so if they get damaged/cut you're SOL. Nerve damage in your face doesn't seem to heal so good either, I've never heard of people regaining proper facial expressions after suffering that. Men who have suffered nerve damage after prostate surgery would pay a fortune if that could be fixed.
