The term cenesthesia , which derives from the French cénesthésie Although its most remote origins are found in the Greek language, it refers to the sensations that a person experiences regarding his own body .
Cenesthesia is linked to the proprioception (concept that is also known by the name of interception), which is the unconscious perception that an individual has about the location and movements of their body beyond the intervention of the senses of sight, smell, hearing and touch. The idea, used in the field of psychology, refers to the feeling that a human being has the existence of his body.
Our organism It has a very wide range of sensory receptors and nerve endings that provide us with internal sensitivity. The so-called proprioceptors They are found in various parts of the body, such as tendons, muscles, vestibular apparatus and joints. When they are stimulated, we can know in what position we are, or at what speed and acceleration we are moving.
In this way, we can say that the proprioceptors are a kind of interreceptors that are grouped in a subsystem in which the receptors are linked to the movement and the balance of the body, as well as those sensitive to blood pressure and chemoreceptors sensitive to the concentration of carbon dioxide, oxygen and pH. Other sensations such as pain, hunger, the desire to evacuate the intestine, temperature and bladder status can also be perceived by these means, which are part of the cenesthesia.
It is often said that cenesthesia is a difficult sensation since it mentions a somewhat abstract question. Every person She feels the inside of her body in a way that only she knows: that experimentation of the internal is cenesthesia.
Just as the description of our feelings, something even more abstract, does not usually coincide with that of our close friends, the same happens with the way we perceive the inside of our body and phenomena that take place there
Take, for example, hunger, one of the sensations that every human being must experience at least once a day: there are those who can not miss even one of the foods fundamental (breakfast, lunch, snack and dinner) and even add others to calm anxiety, while there are also those who seem to be satisfied with a ration of a bird.
The artist Alberto Lopez Claro , born in 1882 in the Municipality of Azul, Province of Buenos Aires, Argentina, is the author of a painting entitled The man (problem of cenesthesia)painted on oil and published approximately in 1945. López Claro adopted the pseudonym of Claudio Lantier in 1931, which is why his work can be found signed with both names.
It is important not to confuse cenesthesia with kinesthesia . This second term refers, according to the dictionary of the Royal Spanish Academy (RAE ), to the perception of the position and balance of the different parts of the body.
Synesthesia, on the other hand, is the sensation which is generated in a body region as a result of a stimulus that was applied in another sector. The notion can also be used to name the proper image of a sense that is given by another image that is experienced by a different sense. The rhetoric , meanwhile, employs the idea of synesthesia to call the linking of two images that come from different senses.
Cenesthesia, kinesthesia and synesthesia, in short, are concepts that are associated with sensations but have different specific meanings.
