Question

All of the following are typical cholinergic effects EXCEPT:

• A. \( \text{A decrease in heart rate and contraction of bronchial muscle} \)
• B. \( \text{A decrease in conduction velocity through the AV node} \)
• C. \( \text{An increase in sweat secretion} \)
• D. \( \text{An increase in pupillary diameter} \)

Hint:

Cholinergic drugs mimic parasympathetic neurotransmission, influencing various physiological functions.

Answer 1

The Correct Option is D

Cholinergic effects typically involve parasympathetic activation, leading to bradycardia, bronchoconstriction, increased secretion, and pupil constriction (miosis). An increase in pupillary diameter (mydriasis) is an effect of adrenergic stimulation, not cholinergic activity.
