DUAL INNERVATION: One organ can receive impulses from both sympathetic and parasympathetic motor neurons (dual innervation); one division increases activity of organ, other division decreases activity of organ. While some organs are innervated by just one division, most vital organs receive dual innervation which means they receive instructions from both the sympathetic and parasympathetic divisions.
