Autonomic nervous system (ANS)

A self-regulating division of the nervous system that controls involuntary functions having to do with the cardiovascular, digestive, reproductive and respiratory systems of the body.  It is sub-divided into the parasympathetic and sympathetic nervous systems.  The origin of the term ‘autonomic nervous system’ is credited to John Newport Langley (1852-1925) who coined it in 1898 and ‘parasympathetic nervous system’ in 1905.
