Why touching your belly button causes that strange sensation?

The navel is nothing more than our first scar, if, as you read, the navel is formed by the scar tissue that protrudes from the umbilical cord, which attached you to the placenta in your mother's womb and served to feed you and breathe during your pregnancy. Once the umbilical cord was cut, the munon that fell behind fell and the navel was left.Having made that clear: Why touching your belly button gives that rare sensation?

Touching your belly button: why does this strange sensation cause us?

It turns out that the belly button is connected to the fibers that lead to the spinal cord at that level It also transmits information from the bladder and urethra to your brain.That is why when you touch your belly button, you are stimulating these same areas.

By digging into the navel in some way you're cheating on your brain to think it's receiving signals from other places, imitating the sense of need of urinating or tingling in the groin.

Deep, behind the navel, everything is covered by the parietal peritoneum, a very sensitive structure and whose sensory nerve fibers go to the spinal cord and whose nerves they send the sensation about the bladder and the urethra to the brain. However, in order for this "false information" to be transmitted, you have to touch the "end of the navel", because only slightly inserting the finger in the navel does not It will produce the same sensation.

Why touching your belly button causes that strange sensation?

In order for this sensation to be described by many as "strange", you must sink your finger with a moderate force in the cavity, since, otherwise, when only is pressed on the skin around your belly button, it does not produce the same sensation, because it is not hitting the deepest fibers behind the muscular layer.

As you have seen if there is a scientific explanation behind that strange sensation we have when we touch our navel.

Even so, with strange sensation or not, the navel is a very sensitive part of our body , and a vivid reminder of the old connection we had with our mothers, even from the womb.Besides that, it is the center of our body and, although, a specific function is not known, it is important to take care of it and dedicate attention to their hygiene, since it can harbor germs that if not taken into account can cause infections.

Regarding the navel you would also like to know that there are different types and there is one that stands out Among the rest for being peculiar: the navels left.What you may not imagine is that there are very few people who have it that way.In fact, it is estimated that approximately only 10% of the population has the navel left. Curious! Right?

Have you also experienced that strange sensation when you squeeze your belly button? Now you know that it is because you send signals about your urethra and bladder to the brain.And, by the way, how is your belly button? Do you belong to 10% of the one we talked to you about?>

Why does this Venus have the second toe so long? It is NOT the only one.Do you have it too?

The man who killed 40,000 elephants by mistake As paradoxical as it may seem, The cause of this disaster was an ecologist convinced: Allan Savory .Allan was born in Rodhesia (now Zimbabwe) in 1935.He belonged to a family of farmers and throughout his childhood he heard that the herds of wild animals ended with the pastures of the extensive African grasslands.Overgrazing was considered for decades the cause of desertification .Because of this, the land was no longer susceptible or of feed the flocks or be cultivated ada .This inevitably led to famine and, therefore, to conflicts between the various human groups that populated these areas. Following that philosophy, between 1955 and 1969 , Allan Savory worked in North Rodeshia and later in South Rodhesia as an independent research and scientific officer .His role was t...

Solar radiation: how does it affect you?

The sun is a source of health and beauty, but according to the frequency and duration of the exposure we make to solar radiation, the effects may be favorable or not so much.Remember that the effect of Sun is not immediate and can cause some problems that we will detail below. Red, reddish skin The skin redness after exposure to the sun , it can take up to 24 hours to appear, since that is the period of time that the blood vessels need to dilate and allow more blood to reach to the cells affected by the rays.Also, it is also what it takes for the skin to make the “ melanin ”, that is the pigment that darkens our skin. The radiations of the Sun and the ozone layer The radiations of the Sun that are received on the Earth's surface change as it passes through the Atmosphere.There are some radiations that are carriers of high energy content, such as gamma rays, UVC, UVB, etc.The effects of these radiations on humans depend on energy, that is, on the ability to pene...

Here we talk about the reasons that usually explain this crying, along with a new and controversial hypothesis.

Are you one of those who enjoy music, no matter what genre? And besides, do you love listening to all lungs? Well, a study indicates some interesting things. What loud music can do to your relationships! An investigation sponsored by Apple Music and Sonos , christened "Music makes home", found 30,000 people and selected 30 families from around the world, as reported by Mashable.com. The study I provide each family with a Sonos sound system and a subscription to Apple Music, and I equip the houses with Apple iBeacons for data collection, in addition to giving them smart watches so that each one could measure their beats and their steps, and a Nest Web camera system in order to record their way of life with and without music in their homes. The first week should take place without listening to music, and as I normally saw vian the second week if you had to use the equipment and put the music at full volume, and the observed behavior was surprising. During the fi...

It was simply beautiful, it lived along the American continent at the end of the Pliocene and became extinct 10,000 years ago.reason? Due to the climatic change of our planet.As the temperature rose, the large dams, the large animals that used to feed: mammoths, horses, prehistoric bison... The smallest animals ran too much and the Smilodon was not a good runner.In addition, he had to face predators more skilled than them, as was the case with the giant wolves.That is, the change of the derived ecosystems by general warming , I have just defeated these wonderful animals, which, without a doubt, we would have loved to know. The Smilodon (saber teeth), a fierce predator First we must clarify one aspec...

Here we go! 6 facts about Einstein that you surely do not know 1.Its authorship on the theory of relativity was debated The theory of relativity was full of accusations of plagiarism by German scientist David Hilbert and his supporters, because Hilbert claimed that it was he who had first discovered the theory and that Einstein had taken all the credit .In his defense, Einstein I affirm that it was Hilbert who had copied some of his documents. At the beginning it was thought that every scientist had discovered the theory by his side, but that was until it was discovered that, in fact, Hilbert had stolen some documents of Einstein without giving him any credit. Einstein published his discovery before Hilbert, who originally submitted some documents...

Will there be a Mega Tsunami in Hawaii?

Will there be a Mega Tsunami in Hawaii? If you are a reader from Science Daily Online and you live in Hawaii do not panic, apparently the possibility that a mega tsunami hits the Hawaiian archipelago in the next 50 years is only 3%, and this information is derived from a study of 5 years by researchers at the University of Hawaii at Manoa (UHM), which began just shortly after the 9.0 earthquake that shook Japan in 2011, and was followed by an even more devastating tsunami. The Investi gators evaluated the behavior of the different plates and tectonic faults that cause earthquakes and tsunamis in the Pacific, as well as the behavior of some large tsunami...
