Unbelievable Human Body Secrets That Will Change How You See Yourself Forever
You ever stop to think about what’s going on under your own skin? I mean, not just the usual “I’m stressed” or “I need a coffee” kind of thoughts—but the actual nuts and bolts of what makes us tick? Turns out, despite scientists poking around for years, our own bodies still hold secrets that’d make your head spin. For example, did you know we might actually have two brains? Yeah, the brain stem and forebrain are genetically different—like having a roommate in your skull you never met. And if that doesn’t blow your mind, try this: every time you remember something, you’re really just recalling the last time you remembered it—not the event itself. Creepy, right? Folks on Threads have dug up all sorts of uncanny facts and personal “wait, what?!” moments that reveal just how bizarre and fascinating our biology truly is. It’s like our bodies are this living, breathing mystery wrapped in an evolutionary riddle that just keeps evolving—and yes, sometimes getting a little creepy. Ready to see yourself in a whole new light? LEARN MORE.
We still don’t know so much about ourselves. Our brains, in particular, are still a mystery even to the most knowledgeable neuroscientists. Despite all the progress we’ve made, we still can’t explain everything.
But over time, we keep learning more about ourselves. And no, we’re not just talking about personal growth or personality traits; we’re also talking about how our bodies actually work. Frankly, we are kind of creepy. And some people on Threads have even shared discoveries that made them see their own bodies a little differently, and here’s what they had to say.
Ooh I have 2:
Recently scientists discovered that the brain stem and the forebrain (lobes) are made of genetically different materials. We essentially have 2 brains.
Also each time we access a memory, you are actually remembering the last time you remembered it, not the actual event.
Before cooking tools became widespread, our ancestors ate a rough diet consisting of roots, nuts, seeds, and raw meat. Naturally, chewing these foods required strong jaw muscles, and wisdom teeth provided extra grinding power. Today, our diets have changed dramatically, and we can even survive on liquids alone- funny how it works.
When you have a c-section, they sometimes they pull the whole uterus out and flop it on mom’s belly and then cut the uterus open and take the baby out. Then they close it and pop it back inside before sewing up the first incision. I had no idea until I was in the OR for one. Whew.
A heart pumps 300 litres of blood an hour. A blue whale is 27.000 + man that’s a lot of blood.
Some people have some or all of their internal organs situated on the other side of the body as opposed to the norm. If all organs are on the opposite side, it is called Situs Inversus Totalis. It affects around 1 out of 10k people. Usually organ functionality is not affected and sometimes those affected don’t even know about it unless they undergo visual examinations.
Some humans can live without a patella (kneecap). They can even run half marathons a couple of years after it has been taken out.
Young children can regrow a surprisingly complete fingertip, but only if the injury is beyond the base of the fingernail.
Our lungs go all the way up to our shoulder. Don’t know why this surprised me. The anesthesiologist told me that when they put the central line in for my son’s heart surgery. When putting the central line in there is a chance of knicking the lung.
When I had my gallbladder removed the surgeon explained that the connecting tube kinda turns itself into a mini gallbladder so the liver still has support, which I thought was pretty cool.
My uncle had two double transplant surgeries. Man was out there with 5 kidneys and 3 pancreas.
A friend has just received a kidney donation, and yes, it was located in a ‘new’ space, which was covered by a tattoo. The surgeon not only added the kidney, but pattern matched the tattoo!
Artistry and genius.
Scientists discovered in 2020 that there are mucus secreting salivary glands called Tubarial Glands that are immediately adjacent to the adenoids near the opening of the eustachian tube in the ear. Up until this discovery, we had no idea these glands existed, and often accidentally removed or damaged them during tonsillectomy and adnoidectomy surgeries.
Some people are born with a little hole just in front of the upper ear rim. It’s called a preauricular pit. Some of them have sinus tracts under the skin that can sometimes become clogged or even infected.
I learned this because I had gestational diabetes and my baby’s blood sugar was on the lower side when she was born. Being in contact with their birthing parent can raise a babies blood sugar up to 15 points. So they had me feed her and then hold her chest to chest. Her blood sugar was perfect after that.
There’s like a small percent of gout patients who have a severe reaction to allopurinol that results in their nails separating from their skin.
Many women’s feet grow in size during pregnancy. I’ve had 2 children and mine grew a size during each pregnancy.
If you only have one fallopian tube it can sometimes reach over to catch an egg released from the opposite ovary. I learned this while undergoing IUI and wondered why my doctor didn’t cancel my cycle when I ovulated on the “wrong” side (I was born with only one tube).
I’m gonna assume this isn’t common, since the doctors only have me as an example (but who knows, maybe others will chime in!) You can develop partial mouth numbness due to severe vitamin D deficiency. Once I upped my vitamin D, it went away!
You have balance receptors in your feet, eyes and ears. Take one away (touch your finger to your nose with eyes open, then close them) and you should be able to do both. If you can’t it may signal an issue.
