Atrophy is a dystrophic process and a decrease in the mass of an organ, both as such and as a result of a violation of the cellular nutrition of the body. There are physiological atrophy (physiological atrophy, forced atrophy or deprivation, “pituitary”, traumatic, adaptive, nervous origin, as a result of hypnosis, against the background of intoxication, diabetic, in the absence of one of the endocrine organs, chronic acromegaly), pathological or parenchymal, local and general; polar, centripetal (giant cells - Beger-Hübner, Moebi cells) and centrifugal (dystrophic changes in fibers). Atrophy may be a consequence of congenital (impaired development of cells in certain areas of the cerebral cortex, congenital atrophy of the optic nerves, dysgenesis of gonadal tissues, testicular aplasia, etc.
