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, 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 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
homeostasis as well.
