Atrophy
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 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 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.

Famous quotes containing the word atrophy:
“The author’s conviction on this day of New Year is that music begins to atrophy when it departs too far from the dance; that poetry begins to atrophy when it gets too far from music; but this must not be taken as implying that all good music is dance music or all poetry lyric. Bach and Mozart are never too far from physical movement.”
—Ezra Pound (1885–1972)
“Unless they are immediate victims, the majority of mankind behaves as if war was an act of God which could not be prevented; or they behave as if war elsewhere was none of their business. It would be a bitter cosmic joke if we destroy ourselves due to atrophy of the imagination.”
—Martha Gellhorn (b. 1908)
“Scepticism, as I said, is not intellectual only; it is moral also; a chronic atrophy and disease of the whole soul. A man lives by believing something; not by debating and arguing about many things. A sad case for him when all that he can manage to believe is something he can button in his pocket, and with one or the other organ eat and digest! Lower than that he will not get.”
—Thomas Carlyle (1795–1881)
