This document provides an outline and overview of the autonomic nervous system (ANS). It begins by introducing the ANS and its role in regulating internal environments. It then discusses the divisions of the ANS into the sympathetic and parasympathetic nervous systems. Key differences between the two divisions are explained, such as neurotransmitters, locations of ganglia, and effects on target organs. Examples of sympathetic and parasympathetic responses are provided. The document concludes by discussing dual innervation of organs and cooperative effects between the divisions of the ANS.
