Definitions
noun
- originates in the brain stem and lower part of the spinal cord; opposes physiological effects of the sympathetic nervous system: stimulates digestive secretions; slows the heart; constricts the pupils; dilates blood vessels
adjective
- of or relating to the parasympathetic nervous system
Examples
The toxin also inhibits release of acetylcholine in all parasympathetic and cholinergic postganglionic sympathetic neurones.
Postganglionic parasympathetic nerves mediate both cholinergic contractions and nonadrenergic, noncholinergic relaxations of smooth muscle in the airway.
The constrictor muscle is supplied by the parasympathetic nervous system, and the dilator by the sympathetic nervous system.
