1. 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. In medical practice, hormonal and nerve inputs that maintain an organ or body part are said to have trophic effects. A diminished muscular trophic condition is designated as atrophy. Atrophy is reduction in size of cell, organ or tissue, after attaining its normal mature growth. In contrast, hypoplasia is the reduction in the cellular numbers of an organ, or tissue that has not attained normal maturity. Atrophy is the general physiological process of reabsorption and breakdown of tissues, involving apoptosis. When it occurs as a result of disease or loss of trophic support because of other diseases, it is termed pathological atrophy, although it can be a part of normal body development and homeostasis as well.

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.

Examples of atrophy in a Sentence

1. Bruce Willis:

   A brain MRI can tell us if certain parts of the brain are shrinking or showing signs of atrophy.

4. Karin Nielsen-Saines:

   Even after the brain is formed, there are some problems that happen, there’s atrophy, there’s damage, even later in pregnancy. So just because someone’s reached the second trimester, it does n’t mean that there could n’t be a problem if they were to contract Zika. ’’ That type of damage can take several weeks to become apparent in prenatal testing. By the time some women learn what Zika has done to the fetuses they are carrying, their access to legal abortion could be blocked in most states. The telephone poll of 1,016 adults was conducted July 20 to 24, during the week when Florida announced it had discovered two people who hadpossibly contracted Zika locally, most likely through the bite of an infected mosquito. Since then, the number of cases in the Florida outbreak — believed to be centered in a one-square mile area just north of downtown Miami — hasswelled to 15. The poll — which had a margin of error of plus or minus 3.6 percentage points — also found that only 44 percent of Americans realized the Zika funding stalemate has not yet been resolved. Lawmakers left Washington last month after Senate Democratswould n’t back a dealnegotiated by House and Senate Republicans that included provisions affecting Planned Parenthood and the Affordable Care Act. Of people who were aware that Congress has not yet provided Zika funding, 55 percent said not passing the legislation is a problem. More blamed the Republicans than the Democrats for the continued impasse — 42 percent said it was the Republicans ’ fault, compared with 22 percent who faulted the Democrats. Seventeen percent said both parties are equally to blame. The apportionment of blame generally followed party lines. About one-fourth of those polled said funding Zika response efforts should be a top priority for the federal budget, nearly half said it was important but not a top priority, and 20 percent said it was not that important. The poll also showed that in the third week of July, barely half of Americans — 52 percent — felt Zika posed a public health threat in this country. And only 22 percent felt that it was a major threat. But it is not known whether the growing outbreak in Florida has changed opinions on that question.

5. Laura Van Doormaal:

   When we first took her home, we were in newborn bliss. Just absolutely in love with her. She was a great baby, but we started to realize her movement was declining. She had trouble breathing and eating. When she was five weeks old, she was diagnosed with spinal muscular atrophy.
