facts about the human body
Redditor u/alwaysclimbing5 wanted to learn a few things about anatomy by asking.... What's a cool fact about the human body that a lot of people don't know?

Bone in the Eye.....
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.
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. ddsmd
Extra Ribs for Free....
GiphySome 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.

The Amazing Brain....
Really late but I discovered this thing during my thesis.
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.
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).
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.
The brain is really amazing... yourteam

The Q-Tip....
GiphySome 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. ArtEclectic
I always cough when I q-tip out my ears! I thought that happened for everyone! When I swab it out I can feel the tickle way deep in my throat. ldobehardcore
Liver Phoenix!
Your liver can regenerate, and much faster than you think. I had a quarter of my liver removed, and a month later it was back. Rock_Robster__
Idk that's about exactly as fast as I want my liver to regenerate. rubywolf27
The Smell of Rain.
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. Nonions
We can smell rain better then sharks can smell blood. I actually just learned about this. There Is a podcast from Stuff You Should Know that goes over all this info. The smell of rain. Yellowbellies2
Palm Facing.... Up
GiphyThere 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. johigangan
The Cerebellum...
A woman was found without a cerebellum, the part of the brain that controls motor abilities of the body. She is alive, and has no real side effects from this condition that we know of.
EDIT: 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. HarryShachar
