MHT CET Biology question

Given below is a table comparing the effects of sympathetic and parasympathetic nervous system for four features (a-d). Which one feature is correctly described? Table columns: Features | Sympathetic Nervous System | Parasympathetic Nervous System

(A)Salivary gland: Sympathetic Nervous System - Stimulates secretion; Parasympathetic Nervous System - Inhibits secretion
(B)Pupil of the eye: Sympathetic Nervous System - Dilate; Parasympathetic Nervous System - ConstrictsCorrect
(C)Heart rate: Sympathetic Nervous System - Decreases; Parasympathetic Nervous System - Increases
(D)Intestinal Peristalsis: Sympathetic Nervous System - Stimulates; Parasympathetic Nervous System - Inhibits

Answer: (B)

Solution

Sympathetic stimulation dilates the pupil and parasympathetic constricts it; in (a) salivary secretion is decreased by sympathetic and increased by parasympathetic, in (c) heart rate is increased
