1. Necrosis

   Necrosis (from Ancient Greek νέκρωσις, nékrōsis, "death") is a form of cell injury which results in the premature death of cells in living tissue by autolysis. Necrosis is caused by factors external to the cell or tissue, such as infection, or trauma which result in the unregulated digestion of cell components. In contrast, apoptosis is a naturally occurring programmed and targeted cause of cellular death. While apoptosis often provides beneficial effects to the organism, necrosis is almost always detrimental and can be fatal.Cellular death due to necrosis does not follow the apoptotic signal transduction pathway, but rather various receptors are activated and result in the loss of cell membrane integrity and an uncontrolled release of products of cell death into the extracellular space. This initiates in the surrounding tissue an inflammatory response, which attracts leukocytes and nearby phagocytes which eliminate the dead cells by phagocytosis. However, microbial damaging substances released by leukocytes would create collateral damage to surrounding tissues. This excess collateral damage inhibits the healing process. Thus, untreated necrosis results in a build-up of decomposing dead tissue and cell debris at or near the site of the cell death. A classic example is gangrene. For this reason, it is often necessary to remove necrotic tissue surgically, a procedure known as debridement.

1. necrosis

   Necrosis is a form of cell injury which results in the premature death of cells in living tissue by autolysis, a process that destructs the cell's own components. It is often caused by factors external to the cell or tissue, such as infection, toxins, trauma, or lack of adequate blood supply due to ischemia. This cellular damage is irreversible and often triggers an inflammatory response in the body.

   mortification or gangrene of bone, or the death of a bone or portion of a bone in mass, as opposed to its death by molecular disintegration. See Caries

2. Necrosisnoun

   a disease of trees, in which the branches gradually dry up from the bark to the center

3. Etymology: [NL., fr. Gr. ne`krwsis, fr. nekroy^n to make dead, to mortify, nekro`s a dead body.]

1. Necrosis

   Necrosis is a form of cell injury that results in the premature death of cells in living tissue. Necrosis is caused by factors external to the cell or tissue, such as infection, toxins, or trauma that result in the unregulated digestion of cell components. In contrast, apoptosis is a naturally occurring programmed and targeted cause of cellular death. While apoptosis often provides beneficial effects to the organism, necrosis is almost always detrimental and can be fatal. Cells that die due to necrosis do not follow the apoptotic signal transduction pathway but rather various receptors are activated that result in the loss of cell membrane integrity and an uncontrolled release of products of cell death into the intracellular space. This initiates an inflammatory response in the surrounding tissue: Nearby phagocytes are prevented from locating and engulfing the dead cells. The result is a build-up of dead tissue and cell debris at, or near, the site of the cell death. A classic example is gangrene. For this reason, it is often necessary to remove necrotic tissue surgically, a process known as debridement.

1. Necrosis

   The pathological process occurring in cells that are dying from irreparable injuries. It is caused by the progressive, uncontrolled action of degradative ENZYMES, leading to MITOCHONDRIAL SWELLING, nuclear flocculation, and cell lysis. Distinguish it from APOPTOSIS which is a normal, regulated cellular process.
