==Description==

==Description==

'''Atrophy''' is the partial or complete wasting away of a part of the [[body]]. Causes of atrophy include [[mutations]] (which can destroy the gene to build up the organ), poor nourishment, poor circulation, loss of [[hormonal]] [[support]], loss of nerve supply to the target organ, excessive amount of [http://en.wikipedia.org/wiki/Apoptosis apoptosis] of cells, and disuse or lack of [[exercise]] or [[disease]] intrinsic to the tissue itself. Hormonal and nerve inputs that maintain an organ or body part are referred to as trophic [noun] in medical practice ('trophic" is an adjective that can be paired with various nouns). ''Trophic'' [[describes]] the trophic condition of tissue. A diminished ''muscular trophic'' is designated as atrophy.

Atrophy is the general [[physiological]] [[process]] of reabsorption and breakdown of tissues, involving apoptosis on a [[cellular]] level. When it occurs as a result of [[disease]] or loss of trophic support due to other disease, it is termed pathological atrophy, although it can be a part of [[normal]] body development and [http://en.wikipedia.org/wiki/Homeostasis homeostasis] as well.[http://en.wikipedia.org/wiki/Atrophy]
