The human body is everything that makes up, well, us. However, there are plenty of fascinating things we don't know about it, or rather, ourselves.

Once you look closer, dive under the surface of the skin, explore the inner workings of the biological systems that ensure our everyday life, you just can't help but admire the marvel that you really are.

To learn more about our bits and pieces, Redditor u/Zenssei made a post on r/AskReddit, asking other platform users to share some facts about the human body that not many people know about. Their call to action was immediately answered.

u/Zenssei said the idea for this post came to them pretty naturally. "I was just watching TV, thinking of [something] I could post on r/AskReddit," they told Bored Panda.

"I have learned quite a bit from the comments such as there is a right and a wrong way to swallow, or that about 20% of people have a bone ridge on the roof of the mouth... It was fun reading through the replies."

As of this article, the post already has received over 56K upvotes and 23K comments, and has become one of the coolest online trivia archives out there!

Its why people in emergencies on adrenaline can lift cars off children. Your body is capable of great strength, but it could also severely damage you, so your brain keeps you a weak, soft bag of jelly.

There are many ways we could look at the human body. "On an evolutionary scale, sometimes we are similar to animals, and sometimes we're not," general practitioner, medical researcher, and founder of PrimeHealth Clinical Research, Iris Gorfinkel, M.D., told Bored Panda. "We're symmetric, [our] basic body structure is similar; we have what's called homologous bone structure. In other words, you can find exact similarities between humans and other animals and how our bones are put together."

"Even our muscles and heart and vascular systems are similar. Our lungs are often similar too. [As well as] the fact that there's a long tube from the moment food enters our mouth to the point at which it goes out of our rectum," Gorfinkel explained. "Their breathing is similar to ours neurologically. Urologically (how urine is formed), we're also quite similar. In all of these aspects, we are very similar to animals."

People-Share-Interesting-Facts-About-Human-Body You hate the sound of your recorded voice because it's missing the low frequency you're used to hearing.

When you talk, you hear your voice as it goes to the air and back to you ear. It also goes through your skull to your ear, and this bone conduction mechanism transmits the low frequencies better than air does.

Your recorded voice only has the air transmitted sound. That causes the dissonance between what you think your voice sounds like, and what it really does. It's also why your voice will (almost) always be higher pitch than you think.

But if we continue to measure ourselves against animals, we inevitably start noticing differences. "Animals communicate across miles of land through subsonic sound, that's true. But human beings, on the other hand, have very complex language systems," Gorfinkel said. "We have introspection—that's another critical difference, [as well as] our creativity and emotions, like joy and sorrow and grief—although grief has been described in some animals, including elephants, wolves, and sea lions. But the biggest difference that makes us humans a complete and utter separate category within the animal kingdom, is our ability to have an imagination, to use language in such a complex way, and to hold fictions in our mind."

The comparison that Gorfinkel thought of on the spot illustrates her point on a meta-level. "Let's just say the lion is the guardian spirit of our tribe. He still could never convince a monkey to give him a banana by promising the little guy, say, an unlimited supply of bananas in monkey heaven. So our ability to create and believe in collected fiction, that's what makes human beings really different."

Some parts of our body, however, remain unknown even to science. Take the human brain for example. It has approximately 86 billion neurons, woven together by an estimated 100 trillion connections, or synapses. So untangling such a delicate network is a daunting task—we don't know the details of how those cells work, let alone how they come together to make up our sensory systems, our behavior, our consciousness.

"You would think it would be easy [to study the brain], it weighs only three pounds, and three-quarters of it is water and 60% of it is fatty tissue. And you'd also think it's easy because the brain can't feel pain. You know, surgery could be done on it, allowing for easy experimentation, as inhumane as it sounds. But there are several things that make it extremely difficult," Gorfinkel said.

"[Our billions of neurons], connected by trillions upon trillions of synapses in a barrel, is a veritable neuronal forest, and the information is moving at all different speeds, some up to, I think, 250 miles an hour. So even with things like functional MRI [we don't get close to] the nitty-gritty of understanding the very fine neuronal connections that are happening, that really define memory, that define all the complexity that I was just describing: language, reason, creativity, and emotions."

Christof Koch, Ph.D., Chief Scientist and President of the Allen Institute for Brain Science, and his colleagues study the brain on a large scale. But the more they look at many or most cells in the brain rather than just a few, the more they realize that even the parts of neuroscience they thought the field had nailed down are more complicated than anyone had realized.

"There may not be any simple path to understanding complex systems shaped by natural selection,” Koch thinks. "Evolution doesn't care about elegance. The brain doesn't care if you understand it."

Interesting fact: Sometimes doctors/nurses will intentionally break the collar bone of a baby passing through the birth cannel in order to help get the shoulders out. Otherwise it could create a hardship on the child and mother. (It depends on how the baby presents during birth. It doesn't happen often but it is a tool they use.)

He stuck closely to my heels all afternoon until I did a sudden change of direction and fell over him. Big fun to break a collarbone on moving day.

You say that as though it were an entirely unsupported structure that is structurally liable to fracturing along a fine line and propped up in a way so as to promote such a fracture, as a brick is in the confidence building exercise - not a demonstration of ability but a method of overcoming certain mental obstacles - and not actually somewhat structurally resistant to flex, and that landing that blow would simply happen with ease and without opposition, and that you actually know what you are talking about as opposed to blowing your own fantastical horn. "Just" snap the collar bone of a maniac conditioned towards strength and aggression who intends you harm... Do this often, or just LARP with peers in a safe, padded environment with strict precautions in place? While it is true that that particular bone is one of the easiest to break and that breaking it might possibly cause someone maybe some hesitancy to continue their assault, anyone who is filling other peoples' heads with the nonsense idea that it is a simple thing to do in a live situation and that it even will necessarily end a conflict is, themselves, a fantasy dwelling f*****t responsible only for the design of those persons' error.

As cool as this seems it isn't entirely accurate. The collar bone serves several functions, like nine muscles are attached to it, and arguably most importantly, it allows for free arm movement that doesn't interfere with the thorax. While it's true that it does absorb impact shock, which helps protect the spine, the collar bone is not a circuit breaker. It'd be more accurate to compare it to the engine compartment of a car, which mainly serves to store the engine, but will crumple in an accident to deaccelerate the car. But the truth is, the collar bone wasn't designed for anything. It just happened to help organisms survive and spread so they outlived the same organisms without it. Vertebrates with collar bones were more agile (and had less spine injuries) so they generally survived more situations than those without it.

That is worrisome that they tried to hide it from your mom. Since you have to be extra careful picking your baby up from their crib etc. As I read it, your mother did find out?

But that doesn't mean we should stop learning. On the contrary. There's plenty we can do as individuals and as a society to get a better understanding of ourselves and in turn, those around us. "Emotional education is sadly lacking in schools," Gorfinkel said. "We teach all kinds of useless things. And I hate to say it... They're not useless, but they're not as relative to us as understanding our emotional selves."

The doctor said there is precious little time devoted in schools to understanding emotions, such as anger, humiliation, shame, guilt, and what to do when we face them. Instead, they're often presented as something negative we need to control, as opposed to being contextualized. These emotions can actually help us, show us the path towards what needs to be done next. "They shine a light on how we need to manage our lives better," Gorfinkel explained.

"That is something that has long bothered me. Emotional education is, for the most part, not focused on; we focus on physical education, we focus on [general] education [like] mathematics, physics, chemistry, biochemistry, whatever it is, but a lot of the time, the most critical part that will determine our happiness, and our productivity is completely overlooked."

Because of that, we have to do it ourselves. "Just make the most of picking the low lying fruit," Gorfinkel said. "I'm talking about [things like] sleep or finding the right amount of stress in your life—stress is an interesting thing. Too little stress is actually bad for a person, there's a sweet spot when it comes to stress. And it's kind of a bell curve, right? That if you have too little, there's not enough stimulation. And a person does not approach self-actualization. Even though stress is roundly considered a negative thing, in fact, a little bit, just the right amount is a positive thing. Of course, it can turn into a very negative thing if there's too much. But finding the sweet spot of stress is probably the best tip that I could give."

When you think about it, the Internet is a beautiful thing. One moment, u/Zenssei is chilling in front of their TV, the next, tens of thousands of people are teaching one another about the human body. More of this, please.

Your body will reduce your muscle strength to protect your spine.

Stand on flat ground, hold your arms out in a t-pose, and have a friend push down on your hand while you try to hold it in place. That's your control, how strong you actually are.

Now, remove 1 shoe (or put a book under 1 foot) and repeat with your hips askew so your spine isn't straight. An inch is all it takes.

Your strength will be reduced to the point that your friend can use a single finger to push your hand down.

After a while, with proper reeducation and all, the children can go on to have a normal life without cognitive deficit. They will have a limping, blindness from one eye and a very weark arm but can lead a normal life and not end up cognitively impaired.

One of the earliest sign of alzheimer's disease, before the memory loss, could be the loss of the sense of smell. It's also the case with Parkinson disease.

The reason it feels weird when you or someone touches the inside of your belly button is because the nerves actually go to your spinal cord. These nerves lie at the same level that relay signals to your urethra and bladder. So when you feel like you have to pee when you touch the inside of your belly button, that's why.

I can't take it. That's why I don't wear elastic in my pants. Can't stand it against my belly button!

People-Share-Interesting-Facts-About-Human-Body You can poop out of your mouth if your intestines get backed up enough. It's like vomit, doesn't look like actual poop per se, but it's still disgusting.

People-Share-Interesting-Facts-About-Human-Body Humans have stripes, we just normally can’t see them. They’re called Blaschko’s lines and form along the paths of embryonic cell migration. The stripes are sort of U-shaped down our front, V-shaped on our back, wavy on the head and face and we have basic, simple stripes on our extremities.

Ha ha, the bot that picks the images and just looked for 'human'+'stripes'!? Good fact though.

Each one of your eyes has a blind spot where the optic nerve exit your eye into your brain. You can't see it because your brain tricks you not to see, it covers the spot with some made up image of what it thinks fits better with the rest of it.

We're the best marathon runners in the animal kingdom and can win a marathon against any animal out there.

AND - that's why we pair with dogs so well, because they're marathon runners also, so we could hunt prey together by wearing it down over time rather than catching it in a sprint or a super quick movement the way many animals do - alligators, bears, birds, snakes, spiders, oh, and obviously... cats ;). That's true!

Your brain likes stimulation, if it doesn't get any it will make some up, some people are more sucepticle to it then others, the colors you see before you fall asleep are a common mild occurrence, there are several classes of these hallucinations, closed-eye visuals, which are caused by leaving your eyes closed for a long time, hypnagogia, which is caused by the onset of sleep, prisoners cinema, which is caused by looking into a dark place for a long time, ganzfeld effect, which is caused by blocking out all external stimuli, and Charles bonnet syndrome, caused by sight loss.



Most are these are simple phosphenes but some can be whole imagined scenes, or more abstract fractal-like imagery

I get the fractal imagery. It is very pretty. Box that I know it is because my brain is bored, I will try to stimulate it more.

When you have a bowel movement, your heart rhythm shifts temporarily due to a vagus response. The reason Elvis died on the toilet was because his heart was beating 200+ bpm and the quick rhythm change caused a myocardial infarction. People with low heart rates have been known to pass out on the toilet because their bodies can't handle the shift.

It's also why EMTs will absolutely not let you use the bathroom before getting on the ambulance. Especially if the bathroom is a standard 5'x8'.

What do the dimensions of the bathroom have to do with poop-based heart attacks?
