It may be hard to believe, but our body is no less than a museum, containing ancient features whose purpose is no longer understood.
From wisdom teeth to the appendix, there are many other things whose purpose of existence is beyond the understanding of scientists.
One of these things is hidden in our hands, rather it should be said that it can still be seen in the wrists of most people, but many are missing it.
In fact, there are 15 percent of people in the world who do not have this thing in their wrist and that is a specific muscle.
If you want to see if this muscle is present in the hands or not, place the hand on a spot table and then touch the thumb with the little finger.
When you do this, will you notice a muscle or line in the middle of the wrist that is somewhat raised?
If yes, then you are among the 85% of people in the world who still have this muscle called Palmis longus on their hands.
But 15 percent of people are born without this muscle in one or both hands.
But this muscle does not seem to serve a particular purpose as its absence or presence does not make a significant difference to grip strength or wrist flexibility.
Most surgeons often remove this muscle during plastic surgery or any surgery on the body.
So why do we have this muscle in our body? The answer is very interesting.
Scientists discovered that although this muscle is present in most mammals today, it is more prominent in animals that are accustomed to rotating the elbow, such as langurs or monkeys.
That is, it is more prominent in the hands of animals that are used to swinging on their hands or, say, spend more time in trees.
That is, there is no real use for it in humans and it is part of our physical evolution that was transferred to us from ancient humans.
In ancient times, this muscle was very prominent, but as the use of thumbs became more common and there was no need to climb trees, its thickness gradually decreased and now it only exists as a monument.
That is, it doesn’t matter if you have the file in hand or not because it is not used.
Interestingly, some people have this muscle in only one hand, some in both hands, and 15 percent are completely absent.
According to scientists, most people have 20 muscles from the wrist to the elbow, all of which help to bend the hands, move the wrists, move the hands, and other functions.
But 15 percent of people have 19 muscles from the wrist to the elbow and the palmar longus is absent.
According to scientists, this muscle helps to some extent in the flexibility of the wrist and is prominent when we move the hands to grasp something, but it is no longer needed for daily activities.
That is, even if you do not have this muscle in your hand, there is no difference in the movement of the hand and wrist.
Well, you can definitely check whether you have this file in your hand or not, the procedure of which is mentioned above.
