Question 8

A patient experiences sudden bradycardia, pupillary constriction, and increased salivation after accidental exposure to a potent cholinergic agent. Which part of the autonomic nervous system is primarily being stimulated?

Accepted Answer

B. Parasympathetic nervous system — Bradycardia (slowed heart rate), pupillary constriction (miosis), and increased salivation are classic manifestations of parasympathetic nervous system activation.
