    What is involution?

    Man does not always move along the path of direct development. Sometimes we can observe reverse processes in development. In this case, talking about involution. Let's take a closer look at what is involution.

    In a broad sense, involution is the reverse development of cells, tissues, organs and the whole organism, the transition to the previous state. In the body, it is characterized by the extinction of any functions. A typical example is the involution of the uterus after childbirth (when the uterus is reduced, acquiring prenatal sizes), the involution of lactation (when the woman’s breasts stop producing milk).

    Also involution may be called the reduction or loss of individual organs in the process of evolution, the simplification of their functions. In addition, atrophy of organs during aging also, in fact, is an involution.

    Separate and sexual involution, in which there is a weakening of sexual desire.

    Thus, involution is a complex process.

    Involution in other areas

    But not only in biology and medicine is found the use of the word. For example, psychologists may deal with an involution of personality when extinction of a person’s mental functions occurs.

    The word is also used by mathematicians to denote operations for finding values ​​opposite to the original. For example, the involution is a function f (x) = -x, given on a set of integers, rational or real numbers.
