Why Cant We Reverse Nerve Damage
Every year, tens of millions of Americans suffer from nerve damage, some irreparably so. Science can heal bones, grow new organs and even restore our microbiomes, but why is it so hard to fix our nerves? Hey guys Lissette here for DNews The human body posses a remarkable ability to heal. Bones refuse, skin wounds mend, and the immune system adapts to infection, after infection. But there’s one area of the body that struggles to recover after an injury: The nervous system. Nerve damage can be some of the most debilitating and permanent type of injury.
The nervous system is an incredibly complex network used to send electrical information throughout your body. It can basically be divided into two sections. With the brain and spinal cord making up the central nervous system or CNSâ€¦. and the nerves made up of fibers of sensory and motor neurons comprising the peripheral nervous system. Each cell in the nervous system from the tip of your finger up your arm, up your spinal column, into your brain, is very specialized. And each has a unique function on the pathway, like a circuit. If one these gets cut or injured, it’s hard for an exact replacement cell to be put in in the right spot. Think about when you get a cut on your skin. If the cut.
Goes deep enough, exact replicas of cells won’t cover the wound, instead fibrous tissues form. which we call scars. And scars are part of the problem in regrowing nerves, they often get in the way especially in the case of spinal cord injuries. As part of the CNS, spinal cord injuries are notoriously difficult to heal; partially because of the way nerve cells in the CNS are made. According to the book, â€œResults and Problems in Cell Differentiationâ€�, the CNS also has certain proteins that weirdly, inhibit cell regeneration. While this might sound like a bad idea, it’s hugely beneficial overall to the formation of the CNS. These cells need.
To grow exactly where they are supposed to, just one out of place could be bad. Like. think of an electrical circuit, each unit has to be in a specific order in specific place to work. If one is out of place, the integrity of the CNS is compromised. Neurons in the CNS also lack certain cleaning cells. Nerve cells are made up of many parts, but they send signals through threads covered in a protective sheet of myelin. These threads are called axons. Axons are the long part of the cell that reaches out to the cell next to it to send information down the line. Like arms handing the bucket down the line in a bucket brigade. So these are obviously super important and need protecting. That’s.
Where the Schwann cells come in. which are only found in the Peripheral nervous system. Schwann cells, which aren’t neurons but GLEEL cells, produce the myelin that help protect the axons. But, a study published in The Journal of Cell Biology found they also clean up damaged nerves making way for the healing process to take place and new nerves to be formed. But the problem is. these Schwann cells are missing from the CNS. What they have instead are myelin producing cells called oligodendrocytes. But these cells don’t clean up damaged nerve cells at all. Which is part of the problem. So unfortunately, according to Richard G. Fessler professor at Rush University Medical.
Center quot;There are currently no therapies which successfully reverse the damagequot; from injuries to the spinal cord. But research is currently underway to examine the potential success of stem cell treatment, where stem cells are injected directly at the injury site. Still, it will take a few years to see the results of such trials. But there are times your body can regenerate nerves. The peripheral nervous system doesn’t have the same blocking proteins that the CNS has, and Schwann cells help heal the damage. So it’s able to regrow nerves, albeit slowly. For instance, if you cut a nerve into your shoulder, it could take a year to regrow. By that time.the muscles in your arms could.
Become atrophied. So, not surprisingly, researchers are working on helping the body heal faster. One study published in the Journal of al Investigation found that a shock of heat made the peripheral nerves grow faster. In another study published in the journal Advanced Functional MATERIALS, researchers used 3D printing to make a sort of guide for peripheral nerves to follow as they regrew. The guide was built with small physical grooves and even chemical cues to help guide the nerve along its new path.

Sciatic Nerve Pain Stretches Exercises Ask Jo
Hey y’all, it’s Jo and my assistant with me today is Bailey again. And today I’m going to be talking about your piriformis. So lots of times I hear people say they’ve got that sciatic nerve, well actually everybody has a sciatic nerve, but you can have pain coming from that nerve, and a lot of times that piriformis muscle is causing the pain. So we’re gonna show you some stretches to stretch out your piriformis and hopefully get rid of that sciatic nerve pain. Alright let’s go on to our backs. Here we go. I think we’re gonna maybe move Bailey out of the way. In the first stretch for your piriformis is a pretty simple one. A lot of pictures you may get from your therapist will actually.
Show one leg down, I actually like for you to have it staying up so you can prop your foot over it. So your gonna make almost like a figure 4 with your legs and then what you’re gonna do, the side that’s hurting, so my left side is hurting, I’m gonna cross that leg over. And what I’m gonna do is I’m gonna bring my knee with my opposite hand towards my shoulder over here. So I’m pulling this leg up and across my body. And what you wanna do same kind of thing with all the stretches, you wanna pull and you wanna feel a stretch under there. Soon as you feel a really good stretch you wanna hold it for 30 seconds. So remember up and across the body. Just coming up is not gonna get that piriformis stretch. But.
Coming up and across the body like I’m trying to bring that knee towards my shoulder. Holding it there for about 30 secondsa real 30 seconds. And then coming back down and you wanna do that 3 times. Now the next one to do, sometimes this is a little harder for people, but what your gonna do is your gonna keep that same figure 4, and what your gonna do is your gonna take your hands and on the opposite side that it’s hurting, so the hurting side is still up crossed over it’s still my left side. I’m gonna take my hands and put them underneath my thigh, and I’m gonna bring my leg up, and I’m gonna pull until I feel that stretch underneath there. Now some people might have a hard time grabbing on to their leg here, so again you.
Can use your belt, or your dog leash and put it under, around your leg, and pull up towards you like this. Same kind of thing, you want to hold that stretch for 30 secondsbye Bailey, we’ll see you later and then 3 times each. Alright, so now you’re gonna bring that down getting it nice and stretched. For those of you that need a stronger stretch, those might not be stretching it out quite as much, what I’m gonna have you do is I’m gonna have you turn over. And what your gonna do is the side that’s hurt again, my left side, I’m gonna bring my leg up across. Now as you can see, this is something you have to be pretty high level, pretty flexible to do, but it’s gonna get a fantastic stretch. So your gonna put.
Your knee over across your body, and bring your body down. So it’s almost that same concept, you’re bringing that knee towards the opposite shoulder, but what you’re doing now, is you’re using your body weight to bring it down. You can stretch that back leg as far as you can. You can bring your arms down, but that knee is essentially going towards that opposite shoulder. 30 second stretch, 3 times each. Alright and there you have it. Those were your piriformis stretches. So if you had some pressure on that sciatic nerve, hopefully that will loosen it up a little bit. So if you like my hair, or if you like the stretches, please click quot;likequot; and leave me a comment. And if you’d like to see some more stretch.
