Parasympathetic stimulation causes
(C) Pupillary constriction # Parasympathetic effects on the organ systems:> GIT: Molility and tone are increased; Secretions are increased; Sphincters are relaxed (usually)> Lungs: Bronchial muscles undergo contraction; Bronchial glands are stimulated> Eyes: Radial muscle of Iris has no action; Sphincter muscle of Iris -- contraction; Ciliary muscle: contraction for near vision> Sweat glands: No response to parasympathetic stimulation. While sweat glands respond to cholinergic stimulation by genized increase in secretion they do not parasympathetic stimulation by the same.
