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 theres 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 CNS. 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, its 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, Results and Problems in Cell Differentiation, the CNS also has certain proteins that weirdly, inhibit cell regeneration. While this might sound like a bad idea, its 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. Thats where the Schwann cells come in. which are only found in the Peripheral nervous system. Schwann cells, which arent 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 dont 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 There are currently no therapies which successfully reverse the damage 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 doesnt have the same blocking proteins that the CNS has, and Schwann cells help heal the damage. So its 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.
Pinched Nerve Cervical Radiculopathy Stretches Exercises Ask Jo
Hey everybody it’s jo, and today i’m going to show you some stretches and exercises for cervical radiculopathy. Let’s get started. So if you have this, you know is pretty ridiculous, and you want to get rid of that pain because it’s nerve pain. Basically what radiculopathy is is the nerve root at the spine gets inflamed and irritated and then it causes that pain usually down the arm or if it’s in the lower body down the leg. So to start.
Off with, we’re just going to do some nerve glides. with nerve glides, remember you just want to do a little bit. Maybe ten just one time a day because if you do too many, it will flare up the nerve even more that’s definitely what you don’t want. So to start off with, take the arm and put it almost up into a stop sign position, but turn your palm facing you, and what you do is imagine that there’s.
A string on your finger and your head so they follow each other. so basically you’re going to pull your head over and straighten your arm out and then come back in. Try to keep your head in a straight forward position, don’t turn towards it, but keep it straight ahead, and then just side bend over and follow that hand going down and coming back up. So again just start off with 10 of these. I wouldn’t recommend anymore because it might flare it up a.
Little bit more. then you’re going to go into some stretching into a trap stretch, and that’s those muscles back here where they get tight they they pull in and put pressure on that spine and put pressure on the nerves. So for the trap stretch, if I’m stretching my right side, I’m going to put my hand down. Some people put it behind their back you can do that. If you’re sitting in a chair, it helps to kind of grab on the bottom of the chair cause then that kind of.
Stabilizes the shoulder because you don’t want your shoulder coming up, you want it to stay down. And then take your opposite hand and then just pull away and hold that stretch for 30 seconds. So you should feel that stretch right in through there, and just nice hold. See if I’m not holding on that shoulder comes up a little bit, and I’m it’s not terrible but then I’m not getting quite as much of a stretch, so make sure you kind of.
Pull it down, you can just take your fist and push it down as well. holding that for 30 seconds and then doing that three times. If you want to do both sides you can as well. The next one is going to be a chin tuck, and we’ve talked about chin tucks in the past where it’s not tucking down towards your chest, but it’s actually tucking it in making a whole lot of little chin’s there. So the goal is to make a whole.
Bunch of wrinkles right there. So what I like to do is kind of use my finger as a target just so I know that I’m actually retracting that chin back. So just starting here, and then it’s almost like I’m trying to take the back of my head towards my other hand. So just scrunching, in getting lots of little chin’s there, but keeping that chin up. Hold it for about three to five seconds, and then relax, and you can see that.
There’s a space now between my finger and my chin, and i moved it a little bit, but you can tell that there’s a difference there. And then move it again and retract. Hold it there three to five seconds, and do about five of those. Then the next one is going to be the chin retraction with a little bit of an extension, and remember with extension if you have neck issues anyways, sometimes this movement for people makes you dizzy or very painful, so don’t feel like you.
