When you're in the market for a slew of very specific facts that all fall under the same general theme, the internet really delivers.
Forget streamlined public health capabilities and revolutionized human communication, the true beauty of the internet is all the random, barely useful information you can find when a bunch odd people decide to assemble and swap info.
<p>A recent Reddit thread centered around one theme in particular: the weirdest things about the human body. </p><p>Doctors were asked to weigh in, but unsurprisingly most of the contributors were non-doctors who read something weird one time. </p><p>But that was probably a blessing for the thread. After all, some of these bizarre facts are real doozies. </p><p>bitictac asked, <a href="https://www.reddit.com/r/AskReddit/comments/kum69x/doctors_of_reddit_whats_the_weirdestgrossest_fact/?utm_source=share&utm_medium=web2x&context=3" target="_blank">"Doctors of reddit, what’s the weirdest/grossest fact about the human body that no one seems to know?"</a></p>

Eyeballs Are Weird
<p>Our eyes are super cool. You would think they all of the blood vessels going into the eye would be behind the photoreceptors, right? So that the blood vessels don't interfere with the light we're seeing? Well, it turns out, that's not the case. That's why we have a blind spot. Its where the blood vessels enter through the back of the eye, and then they spread out around the inside of the eye. So there's a whole bunch of blood vessels in the inside of our eyeballs, and that means that as light enters the eye through the pupil, a shadow of the blood vessels gets cast onto the photoreceptors in the back of the eye. Normally, our brain does a great job of photoshopping these out. But under the other conditions, <a href="https://youtu.be/L_W-IXqoxHA" rel="noopener noreferrer dofollow" target="_blank">it's actually possible to see those blood vessels.</a></p><p>But it gets even weirder. The blood vessels in the eye are so incredibly tiny that blood actually flows through them in a single-file line, one blood cell at a time. The plasma and the red blood cells, which make up the vast majority of blood, pass by completely invisible. But the other 1% of our blood, the white blood cells, can on rare occasions actually be seen! Once again, it requires pretty specific circumstances, most importantly a uniform field of blue light. And it just so happens that the sky on a clear day is the perfect shade of blue to see the <a href="https://youtu.be/FkUwogWzSwk" target="_blank">blue field entoptic phenomenon.</a></p><p>- M<a href="https://www.reddit.com/r/AskReddit/comments/i7fv0d/whats_a_strange_but_true_fact_about_the_human_body/g125v29?utm_source=share&utm_medium=web2x" target="_blank" rel="dofollow">asteringTheFlames</a></p><div class="ad-tag" data-ad-name="In_Content_Responsive_7" style="min-height:280px"></div>

The body is an amazing thing, capable of extraordinary possibilities. We often tend to ignore our bodies, which is a ludicrous thing to do. The more we know about our bodies, the longer we can keep them functioning at 100%. Everything is connected, so everything functions as a whole to keep us breathing and strong. So let's figure out the things that we don't know that we most definitely should.

Bone in the Eye.....
<p>The bone that supports your eyeball, called the orbital floor, is paper thin and has a large empty cavity, called the maxillary sinus, on the opposite side. When you get hit hard in the eyeball, instead of your eyeball itself rupturing, the bone underneath your eye breaks, which is called an orbital floor fracture.</p><div class="ad-tag" data-ad-name="In_Content_Responsive_2" style="min-height:280px"></div>

<p>This releases the pressure from the impact and saves your eyeball. If you crush a beachball against a concrete wall, you can pop it, but if you try crush it against a styrofoam wall, the wall breaks but the beachball is fine. An amazing evolutionary adaptation to protect your eyesight. <a href="https://www.reddit.com/user/ddsmd/" target="_blank">ddsmd</a></p>

Extra Ribs for Free....
<p>Some people are born with extra ribs called cervical ribs which grow from the C7 vertebrae in the neck. It's a weird and rare mutation that a lot of people don't even know they have, although it is also a cause of thoracic outlet syndrome, which is where pressure is applied to the nerves, veins and arteries running into the arms. It can be really painful, and in some rare cases can cause gangrene in the arms. If left untreated it can kill you if you're really unlucky. (source: I have the non-cervical rib induced variety) <a href="https://www.reddit.com/user/WinterF19/" target="_blank">WinterF19</a></p><div class="ad-tag" data-ad-name="In_Content_Responsive_4" style="min-height:280px"></div>

The Amazing Brain....
<p>Really late but I discovered this thing during my thesis.</p><p>We were researching patients with neurological problems and people who had brain injuries and we found a woman in her 30 that had had part of her brain removed. More specifically the area that activates when you move your body.</p><div class="ad-tag" data-ad-name="In_Content_Responsive_5" style="min-height:280px"></div>

<p>Well she was moving and talking with just some minor missteps and theoretically it was not possible, she was paralyzed in the first 3 months after the operation (she was caught in a car accident if I remember correctly).</p><p>We were trying out a new scanner for the brain and we found out that an area of the brain that wasn't supposed to work and control the movement was doing just that. The occipital area (usually controls the vision) was now working as a motor control area.</p><p>The brain is really amazing... <a href="https://www.reddit.com/user/yourteam/" target="_blank">yourteam</a><span></span></p>

The Q-Tip....
<p>Some people will cough if they put something in one ear, a very small percentage will cough if something is in either ear. It is called Arnold's ear-cough reflex. <a href="https://www.reddit.com/user/ArtEclectic/" target="_blank">ArtEclectic</a></p><p><a href="https://www.reddit.com/user/ArtEclectic/" target="_blank"></a><span></span>I always cough when I q-tip out my ears!

The Smell of Rain.
<p>You know the smell of rain, or disturbed soil? It's a compound produced by bacteria called Geosmin, and the human nose is extremely sensitive to it. We can smell it at as low a concentration as 5 parts per trillion. <a href="https://www.reddit.com/user/Nonions/" target="_blank">Nonions</a></p><p><a href="https://www.reddit.com/user/Nonions/" target="_blank"></a><span></span>We can smell rain better then sharks can smell blood. I actually just learned about this.

Palm Facing.... Up
<p>There is a muscle, called palmaris longus, in the forearm missing in about 10% of the population. You can easy test if you have it by putting your pinky and thumb together, while holding your palm facing up, and flex the hand upwards. If 1 tendon is standing out more than the others that's palmaris longus. <a href="https://www.reddit.com/user/johigangan/" target="_blank">johigangan</a></p><div class="ad-tag" data-ad-name="In_Content_Responsive_9" style="min-height:280px"></div>

She is alive, and has no real side effects from this condition that we know of.</p><p><strong><em>EDIT:</em></strong> Okay to clarify, her cerebellum was not removed nor did I do it. She was born without one, and the medical professionals (Again, not me) found out after she complained about a headache which lead to an MRI. <a href="https://www.reddit.com/user/HarryShachar/" target="_blank">HarryShachar</a></p>

The human body is such a mystery. Sometimes it's weak, often it's strong and no matter what... there is always a question of "how is this possible?" Why is the body this way?
Redditor u/Lucario2654 wanted to know what some of us thought about basic anatomy by asking.... What is the stupidest thing about the human body?
