It's wild to think that we've grown organs in labs, built robots that can perform surgery, and started producing mind-controlled prosthetics, but we still don't know exactly how anesthesia works, or what's actually going on when a baby has colic.

For all the incredible progress made in modern science, it seems the human body continues to hold some stubborn secrets. Beneath our skin lies one of the most complex and mysterious systems in the universe, and experts are struggling to piece together how and why it all functions the way it does.

Someone recently asked doctors, "What’s a mystery about the human body that science still hasn’t fully explained?" and the answers came pouring in faster than you can say, "I really don't know." It wasn't only medical experts giving their two cents, but also ordinary people who've been met with blank stares after asking a doctor about something seemingly simple.

Bored Panda has put together a list of the best answers for you to scroll through while you wonder why you get goosebumps, talk in your sleep, or why yawning is contagious. May they serve as reminders that no matter how far we've come, we still have a long way to go.

Have you ever wondered why we have fingerprints? Well, so have some scientists...

Initially, it was thought that the swirly patterns helped us to grip things. But it turns out that might not be the case. "Fingerprints actually allow less of our skin to come into contact with objects than perfectly smooth fingertips would," reports thehealthy.com.

According to the site, some theories about the evolutionary purposes of fingerprints include that they protect our fingers or provide touch sensitivity. But at the end of the day, scientists really don't know.

    Patient lying in hospital bed wearing oxygen mask and surgical cap, illustrating mysteries about the human body science unexplained I was in hospital once and about to be put under sedation - I casually asked how Anesthesia works to which the anesthetist replied "We don't actually know".

    When I got home I did some research - we don't know how anesthesia actually works, we just know that it does.

    I had to get picked up by a "responsible adult" after same-day surgery and be under her supervision for 24 hours. She was cautioned not to let me make any important decisions like buying a car. Thing is, I was totally lucid right after I woke up, and I remember everything.

    Not really true. Like most older drûgs our understanding oh how the body works was very sparce when thy were first found to have an effect. Over time our understanding of physiology has of course increased massively, but in nearly all cases there's only a certain depth we can drill down to, so cellular level is now largely understood, even molecular level in some cases, but there's always going to be more to find out.

    Another "shower thought" you might have had is why some people are left-handed while others are right-handed, or why we even need to have one dominant hand.

    Only about 10% of people are left-handed, and the vast majority are right-handed. Should we not have evolved enough by now for us to use both hands equally?

    Did you know scientists were given a grant to study endometriosis and instead of doing research on how to help those who suffer from it, they studied the attractiveness of people with it? And people with endometriosis were judged to be more attractive and have larger breasts? The article is now redacted at the request of the authors, who said this: "We conducted the study in good faith and according to correct methodology. We believe that our findings have been partly misinterpreted, but at the same time realize that the article may have caused distress to some people. Women's respect is a priority for us and we are extremely sorry for the discontent the publication originated." I will link the article below, BP hides links now.

    I have Fibromyalgia and in the past they said there is no genetic link, it's just caused by physical or mental trauma. No explanation why two people could go through the same thing and only one get it. They did think it was more likely in females though. Now there seems to be a general consensus there is a genetic link, which predisposes people and then they just have to see whether it's triggered. Considering my mum, sister and I, and likely my grandma, all have it I would definitely agree to that. It's a bit like my Coeliac's (another autoimmune condition) disease. When my brother was diagnosed with it, I had a genetic test done that showed one faulty gene out of two. That meant that while I didn't have it at the time, there was a chance I could get it at any time. I developed it about 10 years later, I think the trigger was either being mostly gluten free while living with my brother, then going back to eating more gluten, but who knows.

    Or get so used to it that it becomes "normal". By brain is so good at blocking out pain that I barely notice it at all. I only notice acute changes in pain level. If I break a bone, it'll hurt like hell, but if I leave it alone, my brain will just recalibrate that to zero, and I go on. It's not at all a good thing sometimes. It works in reverse, too. Only when I recover do I realize the extent of my pain.

    "Some of the theories think it's because of the way our brains are wired," says American evolutionary psychologist and behavioral geneticist, Dr. Nancy Segal, adding that "Handedness does seem to have a genetic component that is inherited but there's no simple pathway from parent to child we're able to figure out."

    Segal told CBS News that "lefties" often have a more dominant right side of their brain, while righties have a more dominant left side of their brain.

    Person lying on a pillow with hand covering face, illustrating mysteries about the human body and its unexplained science. Autoimmune anything. I used to think it was pretty straightforward then I was diagnosed with a disorder. Everything is so hit and miss and open to interpretation, even bloodwork. I went from seropositive to seronegative at one point, how??? Do antibodies, rheumatoid factor, and ana just disappear? Or fluctuate? Depends on the rheumotologist you ask.

    Symptoms all overlap for so many similar things and the treatments all work differently for different people until sometimes they randomly don't or do for awhile then quit. Maybe you have Lupus maybe you have Arthritis? Can't be sure so take this malaria medicine about it and let me know if you get mouth sores, your liver swells up, or it does nothing for no reason. Could be the meds, could be a flair.

    Either way it's going to affect parts of your body you never knew interacted. How is your relationship with gluten and dairy because it's about to get weird. Which came first, the depression or the inflamation? No idea, but here's another four pills about it. You're hypermobile ever heard of Elors Danlos or pots? Similar but different but who knows... why did you come in again?

    A couple of wonderful things about the placebo effect is that it can help without harming, and it can still work for some people when they know they are being given a placebo.

I have to see medical numbers change before I will even believe that meds will work, because painkillers just make me sleepy and annoyed, antihistamines give me distonia, medical fish oil did nothing (but Crestor worked), and even my semiglutide hasn't made me "loose weight" because I am a real diabetic 2 and just use it to get my numbers into the green.

    Elderly man resting head on hands over a walking cane, illustrating mysteries about the human body science hasn't explained. ALS.
    It's a horrible disease with no cure, no real treatment, no known cause, and 100% death rate. Diagnosis is often only through a lengthy process of elimination. Typical life expectancy after diagnosis is 2-5 years. It causes slow, progressive degeneration and loss of muscle function leading to paralysis. Probably something autoimmune related which is its own can of worms.

    It has at least 3 common names for the same thing:

    Amyotrophic Lateral Sclerosis (ALS)

    Lou Gherig's Disease

    Motor Neuron Disease (MND).

    Then there's the issue of dreaming... Why do we do it? What's the point?

    “Humans spend nearly a third of their lives asleep, yet science has still very little understanding of how and why we dream,” reveals Health and Wellness expert, Caleb Backe.

    According to thehealthy.com, dreaming occurs during REM sleep, and our heart rates increase when we dream. As with other mysteries, scientists are divided about what purpose dreaming actually serves.

    Young man with glasses and green sweater standing indoors in a room, reflecting mysteries about the human body science hasn't explained. There is still no single concrete scientific model for what consciousness is.

    We know that the brain is a network of neurons that send electrical signals to each other, something like a complex computer. We can observe the functioning of the hardware through functional magnetic resonance imaging (fMRI) scans. We can even identify which parts of the brain are active when we feel happiness, sadness, or recognize a face.

    But we have no idea how this electrical and chemical activity results in the creation of the subjective, first-person perception of seeing the color red, feeling heat, or possessing a sense of self. This is what philosophers call the hard problem of consciousness.

    We are becoming extremely good at imitating the functions of the brain with artificial intelligence, but we haven't even begun to try to imitate the experience itself. It is the greatest mystery that exists.

    I asked my therapist once if she knew whether thoughts are simply chemical reactions in the brain. I don't know. She didn't either. It's a question with no answer. We discussed that for about 20mins. Best session ever.

    A neurosurgeon discovered the switch. While operating, he inadvertently disconnected the claustrum (a netlike organ that connects most areas of the brain). His patient, who had been awake and responsive, shut off like a machine. When he reconnected the claustrum, she resumed responding and had no memory of being shut off like C3PO.

    Yes, talking to yourself and talking to others, communicating. Consciousness is communication and community, we need it in order to survive. Otherwise we would live and die without even knowing. Knowledge of ourselves and the world we live in. However I also believe that every living thing on the Earth has a conscious- ness some more aware than others and communicating in their own unique ways. It is even posited that AI could even develop consciousness through language!

    It’s something like jpg or mp4 compression of all “video” and stripping sound from images and storing them in the areas that deal with those parts. When you remember it all gets decompressed and stitched together again. And since brains like to mostly merge very similar memories as one item to strengthen the “recall” all your memories will be a little different from what actually happened. And every time that slightly different memory is stored again over the old one. That’s why witness statements are so fragile and can accidentally (or purposefully) be manipulated if the interviewer doesn’t choose their was very carefully.

I have dreams about a place that I have never been, in very rich detail. It has a stable, a river, a lake, and rooms filled with costumes as well as a stage and an industrial type kitchen. Has anyone else ever been there? :-) PS: No particular reason why there would be a stage - I'm not an actor or anything¯\_(ツ)_/¯

    Fun fact, dreams are generated by the half of the brain that doesn’t do reading. That’s why anything with text on it will be in random combinations of letters and will most of the time trigger you waking up as soon as you try to decipher it as more of your brain goes online in the attempt to make something of it.

    People with IBS have symptoms but otherwise will have completely normal gastrointestinal investigations, ie there is no structural problem that can be conventionally identified.

    Increasingly it’s thought that IBS may be a disease of disordered microbiota which in itself isn’t well understood. The microbiota even more mysteriously seems to have some connection to the brain and mind itself which may be why IBS is often comorbid with psychiatric problems like anxiety and depression.

Not only do I experience them (guaranteed to be a gut mess within 18 hours or major stress), I also work for a colorectal surgery practice and discuss these kind of things with our practitioners quite often. The microbiota dysfunction is more closely related to IBD, Crohn's Disease, Diverticulitis et al. Those are the effects in the lower half of the GI tract. The upper half (I am not so schooled in that) experiences GERD, heartburn, ulcers etc.

    They don't call it colic anymore. It's acid reflux and, according to our pediatrician, it's caused by an underdeveloped sphincter between the stomach and esophagus. It's not a birth defect, it's just that it's full development isn't necessary until after birth. That's why it takes a few weeks to a few months for it to stop.

    Man in a suit and white hard hat writing on a clipboard inside a large industrial building about human body mysteries. When I was choosing major back in my college days, I had many discussions with professors that essentially reduced to:

    - a doctor never truly understand how to fix a patient's problem (or even why a medicine works), but

    - an engineer can truly expect to resolve a machine's root problem, because there is always a logic to how things work (or not work).

    So I chose engineering and stayed in it for 40 years. No regret.

    The thing about engineering is the object either works or it doesn't. Biological matter is so intertwined with so many causes and effects affecting everything else, it's like untangling a tangled ball of yarn.

    It's a phenomenon that doctors just could not explain, no matter how hard they tried.

    "Numerous DNA studies showed no abnormalities in her genes associated with aging, nor did her parents have a history of abnormal development. Plus, all her sisters were normal and healthy," Reader's Digest notes, adding that scientists refer to her condition as Syndrome X, a metabolic syndrome.

    Person sitting and holding their stomach, illustrating unexplained mysteries about the human body by science. Endometriosis. It’s severely underresearched with no real known cause for why the body will do that. Severely painful to live with and affects more than just “bad periods”. Mine would trigger my sciatic nerve I believe and would cause major weakness in my legs to the point I began using a cane on a daily basis before I had a hysterectomy.

    This one is actually just about us falsely believing that we can feel it and confirmation bias. If you get a feeling that someone's staring at you and you look, but no one's there, then you forget about it. But if there is someone looking at you, you remember that you had that feeling, and get convinced that you felt them looking.

    *We yawn for several reasons, most notably to cool down the brain and to help transition between states of alertness like from sleep to wakefulness. While it is often associated with being tired or bored, these are seen more as triggers than the primary function. Contagious yawning is linked to empathy and social communication, suggesting an ancient form of communication to sync a group's alertness *

    Group of medical professionals in white coats walking and discussing in a bright hospital corridor related to human body mysteries. Most of it isn’t fully explained. Most of it is partially explained. A lot of engineering-types of people come into the hospital expecting the body to be explained- if there’s a problem you simply need to find the bug and fix it let me see the data I can do it myself - and then they get wildly disappointed when symptoms and lab values and imaging don’t correlate one to one, that medications have side effects that sometimes are worse than the problem they are meant to solve, and that replacement of one organ doesn’t fix the rest of the organs that are failing, even if the damage was all related to the first organ. The idea that humans and their body parts have a life span is both innate understood and yet impossible for many people to comprehend. Anyway- there’s more that we don’t know than that we know about how it all works. That’s why science funding and high quality research are important to fund.

I was really lucky to be referred to a rheumatologist who had started a specific fibromyalgia clinic. She has always been great, keeping updated with new information and running her own studies (there was one my mum was part of but I was too young or ineligible for some other reason).

    “We Don’t Actually Know”: 44 Medical Mysteries That Doctors Can’t Explain Epilepsy/Seizures.

    Most people don’t realize this, but in around 60–70% of epilepsy cases, doctors can’t find a clear cause. It’s not that the cause doesn’t exis.

    it’s just that our current tests can’t detect it yet. Epilepsy can come from tons of different things (genetics, brain injury, infections), but for most patients, it ends up being labeled as “unknown cause” or “idiopathic. Or in my case STRESS. W*f

    Science still has a lot to figure out about what’s going on under the surface.

    How we lose accommodation ( our ability to read small print). We have a lot of theories but no concrete explanation as to why. The lens continues to grow throughout our life but it becomes more biconvex which should add plus power to the eye but it doesn't. The ciliary muscle remains functional well into the 90th decade. The lens zonules remain attached and functional throughout life. We think it's a change of all the above. But, no smoking gun. This is why you can ask 10 different eye doctors why we lose our ability to read small print and each have a different reason why.

    Older woman with gray hair touching her shoulder showing skin details, illustrating mysteries about the human body unexplained by science. Frozen shoulder! We know who it tends to affect (mainly middle aged people, diabetics), but the why isn'tfully understood.

    I was heading in that direction, with both rotator cuff and bicep tendonitis bilaterally. My rheumatologist gave me some exercises. I do them regularly and they keep things under control.

    Here chiropractor (at least Swedish and at least for one case) could help! So please do not refer to other countries chiropractors. Medics said its just to wait. First shoulder took over year? Chiropractor fixed the other in a few visits. This is why I think Swedish chiropractors can do good stuff..

    What's the difference between a Swedish chiropractor and a non Swedish one? Honest question.

    Just the brain full stop. Our understanding of how brain leads to "us", is laughably weak.

    The human body is so incredibly complicated that it’s a miracle it’s able to function at all.

    To add to that, a miracle that a human body functions in every stage of growth from a single cell right up to a full grown adult.

    There is no such thing as a miracle. But perhaps OP meant that as a figure of speech.

    Genetics. How was I born with my grandmother's chestnut hair color, my Dad's green eyes and small hands, and my mother's hips and beautiful fingernails? There are six of us. We all look different with pieces of other relatives showing up in facial features, hair color etc.

    Wouldn't this be dominant and recessive genes through the gene pool?

    Yes? Just some recombinations with the genes from the xx and the xy contributors? Or do they mean how some genes can become certain things? That is the interesting question! Not how we get the genes from our parents. But where do the language of genes come from?!

    I consider myself the luckiest of five kids, in terms of my hair. I got the colour and curls from my mum, but my hair is thicker like my dad's so not just frizzy like mum's. My sister's is straighter like dad's but fine and blond like mum. My brothers all pretty much have exact copies of my dad's hair, though two didn't live long enough to know if it would darken as much in adulthood.

    A large gene pool, thankfully. One of nine kids all look so different from each other, and my parents.

    We would need a far more complex mind to do that. And we still wouldn't be able to understand THAT!
