Here is one example when it may occur goose skin. You eat the lemon lolk and feel sour taste. Even imagining this picture, goosebumps run on the skin. Feel? Hair on the skin rises instantly. All thanks to very small muscles, which are attached to the root of each hairs. At the moments of rage, cold, light touch, etc. These small muscles are reduced, and the hair becomes end. In scientific it is called the effect piloarecles.

Causes of the appearance of goose skin.

What is the real reason for the appearance of goose skin? Why is this trembling such an ordinary phenomenon? Experts say it is just an evolutionary biological response. She takes her beginning from those times when our ancestors of the hair cover had much more than now. And the hair end was a kind of protective mechanism. The person acquired an awesome look and seemed more massive. In this way, our ancestors made an impressive impact on their enemies.

By the way, it doesn't remind you to you?

Yes, this reaction is inherent in many mammals. It is often observed in cats, chimpanzees, dictums and other animals. And in combination with a formidable roar, a growl or hiss, it becomes clear that they are better not to touch. For example, as this dickery in the photo.

Unlike animals, people during evolution significantly reduced the number of hairs in their body. At the same time, they lost the opportunity to bring the enemy's thrill in such an interesting way as their hair ended. And here goosebumps stayed.

In Russian, you can meet a sufficient amount of mysterious about the meaning of which is hard to guess. The speech design of "hair end" definitely belongs to the number of such. Fortunately, the origin of this expression helps instantly understand the meaning that is lighted in it. So, where did this turn come from, in what situations it is appropriate to use it, what does it mean?

Phraseological "hair end": origin

In order to figure out the value of this speech turnover, it is necessary to start smash it into separate words. So, "hair end" is a phraseologist consisting of two words. If the value of the first of them is not a secret for those who know Russian, then with the second not everything is so easy. What is the attitude of mysterious "DB" can have the hair representatives of the genus of human?

Standing the end means stretching on the tips of the fingers, stand up. Researchers associate the origin of this speech design with which was actively used in the past times. We are talking about the punch - a terrible adaptation, by whom the executioners stretched the body of the victim during interrogation.

Consequently, "hair end" is a condition in which the hair is pulled out. Why is it going on?

Fear, anxiety

If the brain responsible for the processing of emotions recognizes the danger, the signal is sent to the hypothalamus. The hypothalamus ensures the activation of the sympathetic nervous system, as a result, the body turns into the stress mode. In the sympathetic nerves in the skin, the production of stress hormone begins. This leads to the increase in heartbeat, respiratory impairment. Adrenaline, secreted by adrenal mines, reaches the dermis.

Is it possible for "hair stood on end"? Phraseology describes a stressful state, which is one of the consequences of the processes that are described above. Having reached the dermis, interfere with the work of the whole organism. Including they affect the hair muscles attached to the follicle of each hairs, which is on the body.

With a reduction, the hair muscle affects the follicle (root), forcing hair literally "stand up."

Biological reaction

Hair end - the state with which our distant ancestors faced. Once hair on the human body was significantly more than it is observed now. It is not surprising that they served as a kind of protection tool, which was activated at the moments of danger.

The hair rose endback when their owner discovered the threat of his safety, she was imaginary or real. The kind of man became frightened, with potential opponents he seemed more massive, therefore, stronger. This protective mechanism can be observed, for example, in cats. Noticing a dog on the street, animals fuse their back, their wool rises. Thanks to this, their natural dimensions are visually increasing, which allows you to appreciate the fear of the enemy and make it refuse to attack. Diffases behave in a similar way, only instead of hair needles.

What means

So, in what situations do people usually use the speech design of "hair on end"? First of all, it is used to describe a strong fright. It does not matter whether a person was afraid of a real danger or experienced fear when watching the horror movie, thriller. In all situations, this phraseology can be used to tell about the experienced nightmare.

In some cases, this steady turnover is also used to describe strong surprise, experienced by man. For example, if seen or heard plunged into shock. It is not necessary to experience fear at all.

What are the synonyms exist

The phraseological "hair end" has a lot of synonyms that can be successfully replaced without the slightest damage for the meaning of said or written. Suppose the Speech Design "Clamp on the skin runs" is also ideal for talking about experienced fear. "Blood is fastened in the veins" - another suitable stable turnover for describing this situation. At the same time, blood in the veins can not only be intertwined, but also to cool, drop and so on.

What other options exist, how can I replace the expression "hair end"? The value of phraseologism indicates that he tells about fright. Consequently, the speech design of "Soul went into the heels". It can also be said that "goosebumps running (crawling)."

In addition, other sustainable revs can be used, in which the word "hair" is present. For example, it will be appropriate to say that "the hair on the head moved", this phrase has a similar meaning. Finally, the phraseological design of the "ignition is shaking", also helps to describe someone's fright.

When the almond body is in your brain (it plays a key role in the processing of emotions) fixes the threat (or simply becomes a witness "saw - 25"), it sends an alarm signal to the hypothalamus - your vegetative nervous system control center.

2. Activation of the system

Taking a signal, the hypothalamus activates the sympathetic nervous system - includes the stress mode "Bay or Run". The adrenal glands are actively working. Noraderenalin is formed in the skin of sympathetic nerves - a stress hormone, because of which, in particular, heartbeat is rapidly.

3. Ready for defense

Now you're ready to jump over the fence or, alas, impose in pants. Breathing is studied, the heart knocks the hollow hammer - in order for the adrenaline allocated by the adrenal glands together with blood fasterly scattered in the body and reached - among other things, the skin layer called the derma. Here, in the dermis, adrenaline and norepinephrine are taken to work.

4. Voltage Micromyshts

Stress hormones raise alarm throughout the body. This fate does not avoid the so-called hair muscles - micromshets attached to the follicle (root) of each hairs on your body. Adrenaline and norepinephrine literally dug into these micromsheses, forcing them to shrink and remain in this position to the "abundance".

5. Out!

Reducing, the hair muscle has an impact on both the follicle (for someone's hair stands on end), and on the dermum (which is formed on the surface a tubercle, goosebump). This is an evolutionary protective mechanism, common in humans, cats, dictates, etc.: When wool (needles) becomes end, the animal seems more and more dangerous than in fact. The difference is that a person has long been scared of a goose skin for a long time.
