Top 10 Human Body Parts That Are Useless How many cells do you think your body has? Is it thousands, millions or billions? Well, they’re way more than these. The human body has an estimated 37 trillion cells. These cells come together to form all the different body parts, each serving a unique yet important function.
But as it turns out, not all body parts have a defined function. A number of them have been rendered useless due to millions of years of evolution. Nevertheless, they still hang on. So in today’s video, we’re going to have a look at 10 of these parts that serve no purpose at all.
#10 Palmaris longus muscle
This little known tissue runs from the elbow to the wrist. A simple way to see it is to rest both your wrist and forearm on a table and connect the thumb to the pinky. You’ll see a bundle of flesh crop up in the middle of your wrist. This is the Palmaris longus muscle.
It’s fine if you don’t see it. Studies have shown around 10% of humans lack this muscle – and they’re still doing fine. Millions of years ago, this muscle was an important part of our ancestors’ existence. It added that extra grip at a time when walking was on all fours. That said, so does it mean that people who have the muscle have a far more firm grip than those who don’t? Absolutely not.
Since we adopted the upright posture over 3 million years ago, the Palmaris longus muscle has become useless to the point of being eliminated in some individuals. But maybe it isn’t so useless.
It can be harvested and used elsewhere in reconstructive surgery – that is in tendon grafting.
#9 Tonsils
Tonsils are still useful in a way. As part of the lymphatic system, they help trap disease-causing organisms around the throat.
But repeated disease attack on the tonsils can spell doom for you – you’ll have to deal with sore throats and, in the very worst case, breathing difficulties. Clearly, these aren’t conditions you’ll want to find yourself in.
That’s why you can have your tonsils removed and still go on with your life as if nothing happened. In fact, the tonsillectomy which is the process of removing tonsils was quite a common practice back then. It has only decreased in frequency as late as the 1970s.
But this proves something – tonsils aren't of much use to you. Well, people used to have them removed and yet continued to lead healthy lives. So how’s this possible? Why won’t you be negatively affected if your tonsils are removed?
The answer lies in the fact that they are just a part of the numerous lymph nodes found throughout your body – they’re found in other areas such as the armpits, the collarbone region, and the groin.
As such, when the tonsils are removed, these other lymph nodes can carry on with eliminating the harmful disease-causing agents like bacteria, sick cells, and viruses.
#8 Auricular muscles
The auricular muscles surround the outer part of the ear.
Ever tried wiggling your ears? Were you able to? Whether or not you’re able to wiggle your ears depends on these auricular muscles. And if you’re in the majority, you’ll find that shaking those ears isn’t something you can do. It’s just a few people who can do it and even then, it doesn’t mean much as far as survival is concerned – except for the few stares of wonder.
