Human body partsare pretty remarkable.
Yes, that’s really a number.
Your body also has some 37trillioncells.
Need more proof of your amazingness?
Yes, we’re pretty impressive creatures.
Each and every part of your body is important, right?
Still, there are parts of your body that are far less important than your smallest fingers.
In fact, science tells us that there are body parts you don’t even need.
Here’s just what you could live without.
These surgeries make for$3 billioneach and every year.
When that happened, our molars were being used less and less which led to overcrowding.
What was the appendix good for as a human body part?
Nevertheless, it is thought that the appendix was more useful when humans relied on a more plant-rich diet.
If you didn’t know you had it, it’s okay.
It doesn’t do anything for you anyway.
In rodents and some mammals, the VNO serves to detect pheromones.
While most adult humans have a VNO of sorts, it doesn’t work in the same way.
Well, it actually doesn’t work at all.
You don’t see any nerve fibres connecting the organ to the brain."
Essentially, the organ is there, but it’s not hooked up.
Only some people have this human body part
Ready for an experiment?
While resting the back of your wrist and forearm against a table, squeeze together your thumb and pinky.
Do you see a muscle appear in the center of your wrist?
Don’t freak out if you don’t.
Well, unless you want to be really great at climbing trees.
This muscle is actually most useful when it’s taken from the arm and used elsewhere.
Although most people aren’t born with tails, youdidactually have one in the womb.
Despite losing that tail in development, what’s left of the human body part can still be useful.
According toSpine-health.com, the tailbone helps a person remained balanced and stable while sitting down.
“The tailbone is the connecting point for many pelvic floor muscles,” the site continued.
Although the coccyx definitely sounds helpful, science categorizes it as rudimentary.
As Spine-health.com explained, it is “vestigial (or no longer necessary) in the human body.”
Muscle fibers called arrector pili, which areinfluenced by adrenaline, cause this to happen.
And humans aren’t the only ones who go through this.
“These bumps are brought on by a contraction of miniature muscles that are attached to each hair.
Despite not serving much of a purpose at all, we continue to get goosebumps.
The leading theory has to do with attracting a mate.
“It’s nasty,” the doc opined, “but it’s cool!”
While armpit hair is no longer a necessity, it’s not likely to go away anytime soon.
Whether you choose to remove it or embrace it, though, is entirely up to you.
Outer ear muscles are pretty useless human body parts
Can you wiggle your ears?
Even if you might’t, though, you still have these human body parts.
Compared to other mammals and the few of you ear-wigglers out there our ears are pretty one-dimensional.
Okay, okay, that is a bit of an oversimplification.
Ourearscan analyze sounds while also controlling our equilibrium and coordination.
There’s no arguing that ears are useful and beneficial parts of the human body.
Nevertheless, ourouterear muscles have been rendered essentially useless.
Ear-wiggling, it seems, is but a party trick.
Tonsilsare part of the lymphatic system and do serve a purpose in fighting off infection.
In these cases,a tonsillectomy is still advised.
Healthy tonsils are, of course, useful.
After all,they’re lymph nodes.
That said, they’re not youronlylymph nodes.
It’s because of this that it’s possible to livea healthy lifewithout them.
Did you catch that?
“When present.”
Additionally, some people havemorethan one pyramidalis muscle.
From person to person, the muscles vary not only in number, but also in size.
And, uh, don’t do that.
It even works like a lymph node and helps fight infection.
In addition to dogs, other mammals, reptiles, and birds have third eyelids.
Technically a malformation, it resembles a bump on the rim of the outer ear.
You may have even noticed thatScarlett Johanssonappears to have this “unique congenital anomaly.”
