Vivisection (from Latin vivus, meaning "alive", and sectio, meaning "cutting") is defined as surgery conducted for experimental purposes on a living organism, typically animals with a central nervous system, to view living internal structure. The term is sometimes more broadly defined as any experimentation on live animals (see animal testing.) The term is often used by organizations opposed to animal experimentation but is rarely used by practicing scientists. Human vivisection has been perpetrated as a form of torture.
