In 80 years, we will have an additional artery. But why?

Before birth, each person forabout 9 months develops in the womb. It is during this period of time that the brains, the digestive system and all other organs necessary for life are formed. This is a well-known fact, but few people know that in the womb each of us had organs that disappeared after birth. These include the so-called median artery, which is in the hand of every developingbaby. It is necessary in order to provide the maximum blood flow in the hands, which is necessary for their full formation. Usually this artery disappears by the time of birth, but in some people it remains for life. Recently, Australian scientists found that this artery began to be found much more often than before. Based on this, they put forward the assumption that in 2100 almost every person will have it. But why do we need another artery?

In the future, hands will be better supplied with blood. So, at least, Australian scientists think

What is the median artery?

Most people have at least twoimportant arteries - radial and ulnar. They are necessary in order to provide the limbs with the necessary blood flow. When a person is in the womb, he has another artery, the middle one, which helps the other two. By the time of birth or about a month after this event, this artery disappears. But for some people, it remains for life. Scientists have been studying this phenomenon since the 18th century and they still cannot answer exactly for what reasons this happens.

When you check your pulse, you touch the radial artery

According to the scientific publication New Atlas, approximatelyin 80 years, this artery can become an integral part of all people. Australian scientists tested for the presence of arteries in the bodies of several dozen people who were born at the beginning of the last century. They also checked for the presence of the median artery of the hands of people who were born at the end of the last century. According to their calculations, today an additional artery occurs three times more often than before. There is a chance that in the future, the additional blood vessel will be encountered by many more people.

Human evolution

Scientists believe that saving additionalarteries are a sign that humans are evolving. Why we need an extra blood vessel is still unknown. But, chances are, people with an extra artery in their arm are more likely to survive. It can be assumed that increased blood flow to the hands may contribute to increased finger dexterity and forearm strength. But more research is needed to prove all this. Most likely, Australian scientists will do this in the coming years.

In the future, people's fingers may become more dexterous

But from the additional rush of blood to the hands, side effects can occur. People with an accessory artery often have a neurological disorder referred to as carpal tunnel syndrome... People suffering from this disease feelnumbness and pain in the fingers. The cause of the disease is the compression of the median nerve between the bones and tendons. Treatment for carpal tunnel syndrome usually boils down to exercise and surgical release of pinched nerves.

Carpal tunnel syndrome can also develop from diabetes

It is important to note that the study resultsAustralian scientists raise some doubts. Note that they only studied the hands of 80 people born in the early 20th century. The volunteers born at the end of the century were probably also few. To make such a strong assumption that in a few decades people will have a new artery, it is necessary to conduct a study with a large number of participants. Whether they are going to repeat the scientific work or not is not yet clear. But it is clearly worth doing this, if not for them, then at least for other groups of scientists.

But the fact that the structure of the human body is changing -it is a fact. In early 2019, I talked about a bone called fabella. In our distant ancestors, it was located behind the knee. It is very small in size but could play an important role in human organisms. It is believed to be able to reduce friction between tendons. In the course of evolution, people have lost this bone, but for several decades in a row, it has again begun to occur in the bodies of some people. What is the reason, you can read in this material.
