definition of meanings

The senses are the physiological mechanism that a human being has to be able to perceive elements or situations that make life purely sensitive.

These are five, while their study and classification is due to the contribution of various disciplines such as cognitive psychology and the philosophy of perception, among the most prominent. Below I will list and synthesize the characteristics of each of these, as well as their scope.

The eyesight or vision is one that allows us to detect electromagnetic energy thanks to the visible light that enters through the eye, after this a signal is sent to the brain so that this image can be seen. Indeed, from the biological point of view, the eyes are practically an external projection of the brain and perhaps the main point of contact of our mind and consciousness with the outside. This has been further reinforced in the current audiovisual civilization in which the image is part of everyday reality.

Then we have the sense of taste or flavor that is the one that is responsible for the distinction of the flavors that enter our mouth through the food we eat. Our language consists of four taste receptors (bitter, sweet, salty and acid), although since the last century there was talk of a fifth that a couple of years ago was confirmed; it is called it is called umami and that it has the ability to distinguish the amino acid glutamate that is generally found in meats. Compared to other living beings, the sense of taste of human beings has been reduced, perhaps as a consequence of the use of the language for other relevant purposes, of which the most important, by far, is phonation, that is, the ability to speak and communicate.

Following, we meet the Sense of hearing, also known as hearing, which is one that allows us to perceive the vibrations of the environment that oscillate between 20 and 20,000 HZ. This sense is another of the fundamental ways of contact with the environment and with other people and, despite the limitations of human hearing compared to what we observe in other animals, its abolition is a serious problem for the life of relationship.

The touch It is another of the senses, in which the largest and heaviest organ in the body, that is, the skin, interacts with the outside world. Thanks to touch, we also recognize friendly or harmful external stimuli, as well as the various sensations such as from a caress to a trauma.

And finally there is the sense of smell or smell, this is the other of the chemical senses along with that of taste; but, unlike this one that has 5 precise receptors of the taste, the smell has hundreds of olfactory receptors. In man, its capacity has been markedly reduced, but it is still the sense with faster and more direct neurological pathways.

Meanwhile, the senses that human beings have at their disposal are not limited only to these (of a physiological type), but there are other variants of senses that allow us to carry out and carry out other types of operations that are not limited only to the sensitive issue .

So we meet the sense of balance which is the one that allows us to remain stable at a certain point. Then we have common sense, which is the one that allows us to preserve prudence and good sense in certain situations, since its implementation makes us look in our reason for those beliefs and most common propositions to observe at a given moment and that requires yes or yes an answer from U.S. And finally there is the sense of humor, which is the one that, if we have him, will allow us to live a life and take certain circumstances in a more relaxed way. According to some scientists, a sense of humor is one of the few distinctions between humans and other animals, so the value of this tool should never be underestimated ...
