@@nevergiveup5939 I don't know bro, let us know when you figure it out

​@@nevergiveup5939bro is really out here 💀

Fine😭😭😭😭

Too bad she didn't answer most of the questions. It's a fascinating topic. Why the cop out replies to some of the questions?

@VikingTeddy 😂😂 genius response 👌🏼

There is and has never been such a thing as a saber tooth tiger. There were sabre toothed cats but they were most definitely not tigers by any stretch. Both she and you need to learn some biology it seems.

it went really well together didnt it? i remember having the same example at neurology class when we talked about the sympathetic and parasympathetic nervous system :)

@@jackwhitbread4583Man I bet you're as obnoxious in real life haha

​@@jackwhitbread4583 Why did you get so angry?

​@@jackwhitbread4583And? There are plenty of things that have inaccurate naming. Jellyfish aren't actual fish, pencil lead isn't lead but graphite. The names are simply what is commonly recognized by most, that is why people say jellyfish and not jellyplankton. Maybe you should learn how language works.

I’m a nurse rn and it is freakin cool to know exactly what she’s talking about

@@graciecab6834 rightt!!

I was in nursing school and dropped out same here haha I was so proud of myself

High school biology teaches this.

@@justbreathe_ giving, didn’t get accepted in a medschool

I would say their success rate is pretty high. I am still subscribed solely because their experts have been a good combination of charismatic and knowledgeable.

@@EightPieceBox Let's be real, we're all here for Victor M Sweeney

@@androiduberalles Is he the mortician? If not, what is his field of expertise?

@@bikenyyeah he’s the mortician

She thinks acupuncture is an effective way to treat chronic pain... not so sure I trust her explanations after hearing that

Humans cant want human slaves like that to be left alive, have more made.

Cool! Ha, ‘somehow not surprising’ to you.

You did fictional things?

SAME 😂 going into my second year

Not physically able to communicate?

I love this. ♥

Do you all make puns about it?

In Austria German dialect we call it "das narrische Bein" (i.e.das närrische Gebein) which could be translated as the crazy bone

Hi! I'm just a student so take my explanation with a grain of salt. But basically, lower motor neurons (movement neurons in the spinal cord) have nerve fibres connecting to muscles in your body, and when these neurons are activated, they send electricity to the muscles leading to contraction. Hence, movement! The brain "knows to move" sometimes purely due to sensory information, i.e, reflexes. For example, if you hold your hand on a hot stove (not advisable), sensory cells in your skin tissue, which have fibres connecting to neurons in the spinal cord, sends a signal to these neurons saying that this is a painful stimulus. This sensory information is then sent to your lower motor neurons to flex the arm and thus pull your hand away in a circuit vital for survival. However, this is not a conscious act, since the information never got sent to the brain in this process (this is why reflexes feel automatic). In the more complex case of voluntary movement that I think you're intrigued by, the brain "knows to move" mainly because of a part of the brain called the premotor area, which is next to and connects with the primary motor cortex, the main brain area responsible for sending signals to lower motor neurons for movement. The premotor cortex sends motor plans relating to things like the direction of movement, the force of movement and the sequence of movement, to the primary motor cortex. These movement plans are informed by other parts of the brain which encode more *abstract* things, like desires and emotions for example. This should explain how and why we willingly move the way we want to based off of more complex things than simple sensory stimuli like sight or touch. There are also other parts of the brain which control movement. The brainstem controls muscles of the face, head and neck through the "corticobulbar tract", the cerebellum is vital for muscle memory and feedforward and feedback control allowing for coordination, and the supplementary motor area is hypothesised (among other things), like the premotor cortex, to be responsible for willing movement based on complex associative information and not just based off of sensory stimuli. I hope my explanation helped!

I remember being a little kid and really fascinated by this, I remember waiting in a car and looking up at my hand slowly making it move then consciously thinking "move" and it wouldn't, idk how old I was but that was pretty wild

With ADHD, it doesn't always.

That's humerus

you find them in universities and I heard that US has a few ones that are okay

​@@nevergiveup5939Those are some great questions and the best answer I can come up with is that's just the way it is.

@@nevergiveup5939 1. Because your parents had intercourse. 2. Because the body can't handle the damage over time anymore. 3. No one will ever know

​@@nevergiveup5939bro is really out here 💀

Hands (especially finger tips) and face have a lot more nerve innervation than most parts of the body! This is because we need them to be primed for small tactile sensations as well as temperature. In fact, the hands, face, and genitals take up the most space in the somatosensory cortex, so they quite literally have more brain matter dedicated them than legs, for example. Source: I’m a surgical neurophysiologist :)

“importance of the area where the damage is is being inflicted” i think you answered your own question right there lol

Despite how paper looks the sides aren’t smooth and very jagged, when you get a paper cut you notice how they don’t tend to bleed or scab cause they’re so shallow and it causes nerve endings to be exposed and paper leaves tiny fibers and chemicals in your nerves that irritate it. So to sum it up paper cuts hurt so bad because they don’t cut deep enough to allow blood to scab over and it leaves exposed nerves

Grappig, want ik kan mij niet herinneren dat iemand in mijn omgeving dat ooit heeft gezegd haha. In mijn kring zeggen we "schokbonkje"

In German it's called musician's bone because it feels like a vibration when you hit it

In Luxembourgish we call it the « geckeg Knippchen », which loosely translates as the ‘crazy little bump’

Trom bone

​@@LucemadxD LOL!

LOL!

Same!!! I've stopped taking my antidepressants because my neurologist told me to, and ended up with these awful brain zaps, so annoying

@@queen0fhell193 right?? It feels like the brain is seizing

@michelleruocco2737 yeah and it's kinda worrying at first

@@queen0fhell193jeez what was the medicine doing to leave your brain in that kinda state, I’ve tried anti depressants but none of them worked for me I had to fix my environment

@@queen0fhell193at first homie that sounds worrying period

Or POTS! Would love to see this condition get more recognition because it's not all that rare (esp. post-covid) but yet neurologists are so shy about it making it hard for us to get diagnosed.

Agree!!

yes, i was hoping she'd bring up Functional Neurological Disorder

Me too, I have epilepsy and see a neurologist regularly but was still hoping to hear more on these topics

​@@kellylyons1038I was diagnosed with it, along with tachycardia at 29 yrs old in 2000. I had to have a tilt table test to get my diagnosis. Basically it's when your body can't accommodate the change in position between lying/sitting to standing. Due to the tachycardia, I was placed on metoprolol. Otherwise, they just recommend getting up slowly and drinking more fluids and increasing salt intake. Unfortunately, there isn't much else that can be done except get used to the lovely spinning sensation that is your world for a while. When I get sick my episodes can last weeks. A cardiologist is usually the one who will follow through with POTS cases due to the cardiac component.

I have the beginnings of that. It's called Cubital Tunnel Syndrome

It can also come on acutely if one uses elbows in a fight, or has a particularly gnarly fall... like enough to bruise or chip the bone in the elbow... AND it's anecdotal, just my experience, but a TENS device can help with healing. I dinged my elbow bad enough to lose some of my grip and wrist strength, but religiously used the TENS twice a day, watching my hand flop around like a fish... about a half hour per session, and recovered in a couple weeks. Still sucked, and maybe I only felt like I was doing something about it, but it seemed to feel better... Sometimes you do what you gotta do for relief, even if it only feels different (when anything different would be "good")... haha ;o)

I've literally just started dealing with that this past week. I've always had my hand get numb sometimes when I'm lying in bed, but things REALLY ramped up recently. It has started to wake me up and won't stop until I physically get out of bed and walk around for a while shaking my arm lol it has been having a significant effect on my sleep. I think the reason it suddenly got worse is due to me throwing pottery more frequently now, which requires you to firmly rest your elbows on your legs for stability while manipulating the clay. That combined with me being a sign language interpreter, I feel like I'm really doing a number on these nerves 🙃

@@weekendatmyplace3483 you can counteract the elbow flexion during sleep by taking an elbow pad and wearing it in reverse. That way, you can only bend your elbows so much.

​@@weekendatmyplace3483snuggling a pillow or stuffed animal can help you learn to keep your arms less curled while you sleep. That and shoving padding under my elbows when I lean on something is how I dealt with my issues.

If you look up the nervous system and look at the teeth area, a ton of nerves run into the teeth. So that may be why.

@@justabookworm1382 But why does it continue to fire when I just touch the skin? It's like a phantom thing. It's like the nerve became visible or something after that needle hit it.

@@meghanmonroewhat you are experiencing is uncommon but not that rare after dental procedures , there is a nerve called the trigeminal nerve, branches of which give sensory innervation to the face and they can get damaged during procedures , causing intense pain . It’ll go away most likely but do contact your doctor if it doesn’t .

@@frubbs7083 This was at least 2 or 3 months ago. It doesn't hurt, it's just uncomfortable. It's almost closer to a pins and needles than anything at this point, just specifically when I touch that spot on my chin. So strange.

I sure hope your dentist wasn't asking you "Is it safe?" Seriously, though, I hope you're able to get an answer.

There are just so many variables that account for an individual's pain tolerance. What she said wasn't inaccurate, it just lacked nuance (per the type of format this media is in, no fault of her own). Some people experience lower distress/pain tolerance after trauma, but some people experience *greater* distress/pain tolerance after trauma. It just depends on all the other factors involved (including genetics). Women are also somewhat desensitized to the *type* of pain specific to uterine cramping (as compared to men, or people that don't have periods), because it happens to us all the time (see: videos of men vs. women experiencing abdominal cramping with a TENs unit). That's not to say cramps and labor don't hurt, but we don't experience that pain on the same level as we would if we *never* had any abdominal cramping. :)

@@caseygunn1717yeah, I was somewhat confused by that answer. It sounded like she said being female leads to a lower pain tolerance? Honestly I wouldn’t have thought gender had any bearing on it at all. I can totally understand being desensitised to a pain you feel regularly, like your example of women regularly getting abdominal cramps. I have a host of old injuries that constantly cause pain, but I barely notice them anymore because they’re always there. So it makes sense… but why would being female lead to lower pain tolerance in general?

Brain zaps are a very common occurrence after coming off of anti-anxiety/depression medication, your doctor really should have known about them.

@@CorinaStadler i was also in the middle of taking them when it happened, she said it was her first time hearing about anything involving brain shocks, we're in a small ish town so

I’ve had that too, it was on Cymbalta (duloxetine). Brain zaps are weird.

Taking atypical antipsychotics can cause them too. I used to get brutal brain zaps when I was on Geodon.

Yeah fr same hahahaha

😳😳😳😳😳

Go for it!

@@kennyfresquez7019 I will! Thanks.

If you want to give it a shot, not nearly enough doctors in the world

Yes, and there is also "fawn" and "flop"

I’m a freezer 🥴

Also fawn.

​@@DizzehxxMitizzeh42what the heck is flop 😭

You didn't think about how smart neurologists are? The brain is probably one of the most complex things humans have so far encountered and they kind of understand a bit of it. That's smart.

As an RN of 26 yrs with double sciatica, I can tell you that all humans (with the exception of musculoskeletal deformities) have the nerve in a pinchable area. It is pinched or painful when the muscles tighten or become inflamed causing the nerve to become irritated or the pelvis to shift out of place and pinch the nerve. Strengthening exercises for the abdomen, buttocks, and lower back can help to prevent it as long as your doctor approves them. There are other remedies for relief, but those require a doctor.

We sit a lot in our society. I had a client who sat a lot because he was a truck driver and he had his huge wallet in his back pocket the entire time he drove. Helped a lot when he removed the wallet but of course he was still sitting all day. Definitely something he needed to see a PT for but he was a grumpy old man who wanted me to just fix it 😂

We are one of the few bipedal animals. We evolved over time to walk upright so maybe that change didn’t account for sciatica pain

Even better, she mostly leaves them out entirely.

I doubt Most people would understand that, If Science even knows the exact how and why and IT would Take forever

Wikipedia is wrong then Sources, I can't link any, but if you look up the words acupuncture meta-analysis, you'll see scientific articles about it

I would see a specialist--someone in neuro, or maybe even an orthodontist since it's mouth-related. You might have an underlying, continuing infection that's causing the issue, and need to get checked for that. In the meantime, zinc can help with immune strength.

Ha, yeah.

Curious . . . .i have high Histamin and both a Low and high pain tolerance dependend on what Typ of pain WE are talking, my migrains and Periode pain are debilitating but since I am so used to those, the later are so bade they have me faint and throw Up bile on a regular basis, i react very little to other Typs of pain to a Paint I deeply unnerve people trying to treat me, breaking something Just really does Not compare, Burns, whatever, teeth threatnent without numbing, way less of a hessle then dealing with having to wait for the Feeling to come Back after
