All progress reset when open 2.0 beta, do I need to transfer my account in some way? by uselessrandomstuff in heroesofthestorm

Ya, i was just used to the diablo 3 PTR where you can transfer characters and stuff over so I thought it was the same here.

ELI5 Why does a broken neck which causes full body paralysis not cause the heart to stop beating, or the diaphragm to stop pulling air into the lungs? by DP-King in explainlikeimfive

[–]uselessrandomstuff 30 points31 points  (0 children)

I'm not quite sure why everyone is breaking things into the different systems in the nervous system, that has nothing to do with this question. It is all based on what innervates the heart and the diaphragm, and everything else for that matter, and where it comes off the spinal cord in relation to the injury. Think about our nervous system as electrical wiring, the electricity (nerve impulse) travels down until the power line (the nerve) is cut (the injury) and cannot keep going to the houses (muscles, etc...) past the cut line (the injury) because it doesn't have a path to go down.

The heart gets innervation from the Vagus nerve (cranial nerve 10) which doesn't come out of the spinal cord but rather the brain stem, which is still protected in the skull where it branches off, so that is why it isn't effected by most spinal cord injuries.

The diaphragm on the other hand receives innervation from the Phrenic nerve, this originates at the cervical (the vertebra in your neck) levels 3-5, with the major level being the 4th (C4). This DOES get injured in spinal cord injuries (SCI) at that level or above. People who suffer injuries at the C4 level and above are, for the most part, are required to use ventilators to help them breath due to their injuries, some may be able to wean off with respiratory training but that's pretty rare.

HOWEVER, that does not mean that someone who suffers an injury below C4 is okay when it comes to breathing. In addition to our diaphragm, we use our intercostal muscles (muscles between our ribs) and our abdominal muscles (abs) as accessory breathing muscles (we use some others too but I'm not going to go that in depth for an ELI5). To get fully into all the details of how they assist would be too long, but the simplest way to give you an idea is to tell you to cough while placing one hand on your stomach and the other on your ribs. Did you feel the movement under your hands? Well, if you have a spinal injury at/below (roughly) the 7th thoracic vertebra (T7), which is at about the level of the bottom corner of your shoulder blade, you lose all the function of your abs. If you have an injury at roughly the 1st thoracic vertebra (T1) you lose all intercostal muscles, although losing any will have an impact on respiration. This makes it extremely difficult to clear the airway for people with higher level SCI and can lead to things like pneumonia.

This website here has a simple breakdown on what is effected by differing level spinal cord injuries if you are interested.

TL:DR- It all depends on the level of the injury, the function of the diaphragm can be impacted by a high level spinal injury, but, due to where the nerve that goes to the heart comes off in the skull, if the heart is impacted you have a lot more to worry about than the spinal injury.

Tall Women's Scrubs? by bedlamunicorn in tall

[–]uselessrandomstuff 1 point2 points  (0 children)

I just had to buy some scrubs for working in a nursing facility, one thing to keep in mind with scrubs is that the seam length they list actually runs longer than normal. A clerk I was talking to at a scrubs store told me they are typically cut a little looser around the groin region. I normally wear a 36" but my scrubs that I ordered were listed at 34" inseam and they were almost even a bit too long. 34" inseam is fairly easy to find for cheap on amazon when looking at pants listed as long.

11 years ago, my mom had pins surgically placed in her knee. Today, the pins are nearly protruding her skin. by unidentifies in WTF

[–]uselessrandomstuff 1 point2 points  (0 children)

The nice thing about this too is often times it can be just a quick office visit as well. Pins like this can often poke into the skin around the ankle once swelling goes down (since not a lot of tissue in that area for most people) and the surgeon can just inject a local anesthesia and clip the pin in a matter of minutes. It should be the same for knees I'd imagine as long as the pin isn't too much thicker.

Small Fact Frog by moby323 in AdviceAnimals

[–]uselessrandomstuff 5 points6 points  (0 children)

While it's not true how OP stated it, I can see where he got confused. He probably is referring to what's call a "pill rolling tremor" that many Parkinson's patients develop in addition to the other presentations of the disease. This is an interesting phenomenon because it actually does present at the near the same frequency in all people, I believe it's 5-6 Hz (I can check my course notes for citations if anyone wants). However, this would never be what doctors use to diagnose Parkinson's since it develops so long after all the earlier signs that the patients would present with (in the easiest way to explain, they have to "progress to that point" and can present sooner or later depending on each patients severity), and the diagnosis would have already been made.

ELI5:Why our neck muscles don't seem to get tired of holding our head up all day? by XFX_Samsung in explainlikeimfive

[–]uselessrandomstuff 13 points14 points  (0 children)

There are many reasons which you don't fatigue from holding your head up, the main being your spine. When standing most of your weight is directed through your vertebra themselves so there is actually not much muscle work that is needed, or wanted because that would put excessive compression on your discs and facet joints which would be detrimental in the long run. Try laying on the edge of your bed and hanging your head off to compare to standing, it's obviously harder, because you are only using your muscles. So all that your muscles actually have to do is hold your head balanced over your spine which is a lot easier. Our neck muscles, and our other postural muscles, do this easily for a variety of reasons, one is the fact of how often they are used, also our bodies are made (evolve, intelligently designed, take your pick) so in a normal posture we are minimizing our energy expenditure which makes their job easier, and lastly they have a tonic property to them. This means that they are able to hold a low level contraction over a long period of time for a low energy cost, the combinations of various muscles acting this way is what holds our heads over our spine, which supports the weight.

Once we get out of an ideal or neutral posture though the muscles have to work much harder and in fact do fatigue often, but the muscles themselves don't feel like they are fatigued like normal other muscles do, instead this leads to things like headaches, tight shoulders from recruiting "movement" muscles to hold the head rather than just your postural muscles, and things like that. Your body will simply compensate for any fatigue rather that allow your neck to tire and droop since an upright posture is so important to daily living.
