• metaplasia
  11 July 2003

  Definition: Metaplasia is the reversible replacement of one differentiated cell type with another differentiated cell type.
  Metaplasia causes precursor cells to change their cell fate, and do not change existing differentiated cells.
  Metaplasia is reversible and usually occurs in response to chronic irritation and inflammation and allows for substitution of cells that are better able to survive under circumstances in which a more fragile cell type might succumb.
  Metaplasia is a (...)

• hypertrophy
  3 June 2003

  Definition: Hypertrophy refers to an increase in the size of cells, resulting in an increase in the size of the organ.
  Pathogenesis
  The hypertrophied organ has no new cells, just larger cells. The increased size of the cells is due not to cellular swelling but to the synthesis of more structural components.
  Cells capable of division may respond to stress by undergoing both hyperplasia and hypertrophy, whereas in nondividing cells (e.g., myocardial fibers), hypertrophy occurs.

• bridging necrosis
  27 January 2004

  Definition: Bridging necrosis is the term given to confluent necrosis linking terminal venules to portal tracts. The term "Bridging necrosis" has been used for necrosis linking any of the vascular structures, but it is now more often restricted to the linking of terminal hepatic venules (centrilobular veins) to portal tracts (central-portal bridging necrosis).
  Bridging necrosis describes the location rather than the type of necrosis. It usually results from extensive necrosis of confluent (...)
