What is common knowledge in your field but shocks outsiders?
We don't all have the same number of bones or muscles. There's an average, I guess. We all kind of cluster around it. Some muscles are pretty rare. Some people just invent their own artisanal bones.

Court ordered therapy almost never works and usually makes the problem worse.
Can lead a horse to water, but you can’t make them stop harming their kid/spouse, the kid/spouse won’t rebuild the lost affection, and mostly abusers just learn to be more efficient and cruel abusers.

Again: bodies are a scam. (but this is also very cool?)
Community homelessness is a rich city problem, positively correlated with high housing prices. Poverty rates and substance abuse rates do not predict community homelessness. **

Captain Caaaaavvvvveeemaaaaaaaan!
I shared a clip of Captain Caveman, a Saturday morning cartoon character with super strength and a throwback sense of humor. Yeah, I'm GenX.
Only thing that's basic is their understanding of the world
which bones are typically missing?
like an ear bone?
my brain is having a hard time with this
No way I'm beating that but: you don't need to worry about the 0.5% ABV in a non-alcoholic drink. There may *technically* be alcohol there, but you'd find just as much in a ripe banana, in bread, occurring naturally in your own body, etc.

(because I had to look as well)
(Also this: )
(My youngest sibling had similar 🦷 nonsense)
Some of them are rare enough we've only seen them a few times and we're not sure. At a guess, chondrohumeralis probably enables chest movement but I don't KNOW.
His doctor was very interested in how *that* worked.
I think ears are also learned - i spent a lot of bored idle time in high school one year learning to move one muscle to move my right ear. never managed the left

The tendon runs through the carpal canal, which might increase pressure there unless the canal also widens.
It even runs to the 2nd metacarpal, putting it on the same side as the nerve.
I can tell you overall that these differences aren't usually a problem in general though. Sometimes what we think of as normal isn't even the most common.
OH COOL THERE'S MORE THAN ONE o.O
I am not a contortionist, but I guess the option is still available.
This is NOT my field, but I am amazed at all the ways normal pregnancies can go awry.
It was good practice for when I started learning about bird anatomy, which is weirder.
True fact, no joke. Nice guy.
McDonald's in America.
But yes I studied human muscle identification on a very tolerant cat.
good retort tho.
Most researchers think they know how to develop search strategies & the results show they would benefit from a librarian consult #medlibs
I think I always assumed this was universal because of how many breathing exercises there are where you breathe through your mouth vs your nose at different times
Unlike the nasal closing I have found no practical use for this!
"I had no idea anyone could do this!"
and
"I had no idea there were some people who could not do this!"
It's something that apparently almost never comes up!
It's a miracle it works AT ALL, and if the weirdness won't kill you, well, turns out you're gonna have it.
And this is how we discovered MPTP, which is used to this day to study Parkinson's disease.
wiki disagrees on how we found out
I also recall the mexican surgeon who put stem cells into brains of late stage parkinson's patients with miraculous rapid recovery and congress demanded action and the FDA/NIH wasted so much time and money on that
Also: Artisanal Bones is the name of my new band
Except for full image drawings. Then you research sports med how to safely work on a male/female pelvis.
People can/do donate themselves to med schools. My uncle, a doctor with a serious illness, did.
Guess I got used to it fast--I didn't mention it much!
(It's not, she had to get surgery)
Wisdom teeth, though--some people get none, there have been cases of people with 12.
I had three; my boyfriend in college had six.
Without a seatbelt an airbag provides no effective protection in a car crash.
The human body never ceases to amaze.
So foot anatomy is kind of “on average” guesswork
And everyone’s ears are a supposedly a little different, sort of like fingerprints
I haven't been shocked by anything for ages, this really made me question my understanding! Now I want to know all about it!
Amazing! Thanks!
huh.
Especially if your teacher also points out that cutting the tendon means the finger can’t be controlled anymore: literally puppet strings
(And then everyone in class wriggles their fingers nervously…)
this is common enough that it’s got a name, retrograde uterus
it also means back labor and period cramps you feel in your börthøle
Excellent band name.
Turns out it was just weirdly placed.
It’s a strange phenomenon, the laws of nature defied

It's called a duodenal malrotation and apparently is no biggie.
(Middle ear bones for those curious.)
1 guy I slept with only had one testicle because of an unfortunate "walk it off" situation that ended up being testicular torsion. But! Another guy I slept with had 3 testicles. So the average number of testicles of men I slept with stayed at 2.0

PS. Is that why some people can wiggle their ears?
Generally though, I love the term 'Artisanal Bones' and I'm going to steal it
Some fruit and vegetable oils can become massively toxic and dangerous at concentration.
For example look at this garlic oil safety data sheet: flammable, corrosive, skin irritant.

I LOVE BlueSky!
He never noticed until I pointed it out.
Anatomy class in college:
"The great diagnostician is asked to assess the patient with puzzling problems. The doctor comes before the class, the patient disrobes, and the doctor stares. Suddenly he says: Sinus inversus!"
The right nut was lower than the left
Writing a good children’s book is hard and takes a lot of work.
and some of my other teeth have weirdly shaped roots.
One the roots on my wisdom tooth has twisted around 90° to be parallel with the top of the tooth (it broke during extraction but I glued it back on).
(Also, hello fellow high pain threshold person!)
thinking of taking up competitive head-butting
Every other post I've seen for this prompt made me think, "Hmm, that's interesting."
This one was more like, "Dafuq?! Why are bodies so weird?"
i am learning i am an unusual person, through this thread.
My mom had a couple extra tailbones. And extra thick kneecaps—that one I inherited. It's nice because, while they are not beautiful, they do seem to be virtually unbreakable.

I was like, "Oh well that explains bisexual sitting positions".
*gasps in queer girl with extra lumbar vertebra*
There are so many ways we are different from each other but recognizably human and I think that's neat.
Bodies are weird!
Badly installed electrics may well work, but the cable your Husband/Uncle Terry put in, unless it’s been properly thought out and installed is more likely to make your house catch fire than for you to get an electric shock.
Counterintuitively, much more variation right around the heart than on the periphery!

Her twin sister has neither issue, but isn't an identical twin anyway
My daughter is a fairly advanced pianist, and constantly have to explain to teachers that her thumbs simply aren't able to bend the way they ask, because she has extra bones.
My husband has this muscle in BOTH forearms and that man has brutal grip strength.
