Incredible facts
How many feelings does a person have?
Most people assume that we only have five senses, but others who are aware know that there are no more, no fewer, but 21. So when you hear someone say they have a sixth sense, they're probably right, although that doesn't mean they can see the future.
Having a wide range of feelings is extremely surprising for many people until they realize that they are using them every day without even paying attention to it.
Many of the human senses that we take for granted are incredibly important for the smooth functioning of our bodies.
Human sensory organs
10. Feeling full
When we eat or drink enough, our bodies always let us know. It turns out that this is a separate feeling in our body, which consists of its own set of sensory receptors that tell us when to stop eating.
Some of them are so-called “stretch receptors”, which help us understand that the stomach is full.
The stomach, in turn, sends certain signals to the brain during the digestion of food. This means that if you eat slowly, you will feel full in the right amount of time and will not overeat.
It will be the other way around if you eat the same amount of food but in a short period of time, so it takes time for our brain to realize that we are full.
Types of human feelings
9. Thermoreception
Having this feeling is unlikely to surprise anyone, but it's important to note that feeling hot and cold isn't part of our sense of touch, it's actually a separate sense.
Our thermoreceptors separate hot from cold and allow our bodies to adapt to changes in ambient temperature. Thermoreception signals work through the spinal cord, thus reaching the thalamus, to which they provide the necessary information.
8. Feeling the amount of oxygen
The purpose of “peripheral chemoreceptors” is to monitor blood flow in the arteries, as well as monitor oxygen, carbon dioxide and pH levels. When something happens, they warn us that the level of carbon dioxide is too high, so the human body automatically rebuilds and breathes according to the “established norm”.
In addition, our bodies have special receptors that tell us how full of oxygen our lungs are, so our brain knows exactly when to breathe in and out.
7. Trigger zone chemoreceptors
These receptors primarily interact with drugs and hormones that our body conducts through the bloodstream, and they tell our bodies when it's time to snatch, if we suddenly feel nauseous.
If these receptors are damaged, this can lead to regular vomiting and sometimes a complete loss of the ability to vomit. Such damage usually occurs after heart attacks.
6. Magnetoreception
Did you know that our body has the potential to determine the direction of motion based on its sense of understanding the Earth's magnetic field?
Although there is still some debate about our ability to use this sense, it is clear that it would be incredibly useful for navigational purposes apply it.
Some people, however, have a supernatural sense of direction, and they can use magnetoreception at a higher level than an ordinary person. Therefore, they can easily indicate, and without using a compass, where is south and where is north.
This feeling is most pronounced in bees, some birds, and cows.
5. Vestibular sense
The vestibular sense is also known as “equibrioception,” which is more like the name of a hallucinogenic movie. People know this feeling as a “sense of balance”. Many of us have experienced the hard way in which this feeling is impaired when drinking large amounts of alcohol.
Our sense of balance is regulated by the inner ear, and although it is part of the hearing system, it is still a separate sense.
4. Itching
In fact, this feeling is far more important than the usual itch you might think of. To begin with, from time to time, itching appears completely separate from the sense of touch, and serves extremely important functions.
Despite the fact that this feeling may initially seem more like a nuisance than a useful tool, itching is no less important than touch, because it sends signals to the brain that Something is wrong with a certain part of the skin.
In some cases, it may be just dryness, in others, it may be the presence of microscopic microbes hiding in the hair follicles, which are removed during scratching.
A single itch signals to the brain that you need to look at the affected area and find out what is happening to it.
3. Nociception
Nociception is a feeling that helps you feel pain. Some people think that this feeling is part of the sense of touch, but in fact, pain is something completely different.
Moreover, many experts say that the feeling of pain should be broken down into three more “subsenses”, each of which is associated with different types of pain:
– pain related to the skin;
-pain associated with bone tissue;
– pain felt by the body's organs.
While these are more like subcategories than individual feelings, the actual feeling of pain is much more than meets the eye.
If you don't feel pain, this is a signal to your brain that there are serious disorders in your body and that your body is in danger.
2. Chronoception
Chronoception is a sense of time. It is quite well developed for most of us, especially among young people.
Part of this feeling is controlled by the suprachiasmatic nucleus, which controls our circadian rhythms. Although a person's ability to perceive the passage of time is generally very useful, this feeling can be easily fooled like any other.
Each of us has experienced situations where it seems to us that time goes by faster or slower than it actually is.
1. Proprioception
Proprioception is about knowing where our arms and legs are in relation to the rest of the body. This is what police officers test when they test a driver's sobriety by making him do things like touching the tip of his nose with his finger.
We all take this feeling for granted, but if it were taken away from us, we would miss it very much.
However, there are still rare cases that are a mystery to doctors when a person loses this feeling. When this happens, the easiest tasks, such as opening the door, picking up a cup, and others, become overwhelming.
Such people have to carefully monitor their every movement in order to use their limbs properly.
