Question

Which of the following options correctly identifies the effect of sympathetic and parasympathetic neural system on given features or organs?

• A. Feature/organ - Salivary glandsSympathetic neural system - Stimulates secretionParasympathetic neural system - Inhibits secretion
• B. Feature/organ - Pupil of the eyeSympathetic neural system - DilatesParasympathetic neural system - Constricts
• C. Feature/organ - Heart rateSympathetic neural system - DecreasesParasympathetic neural system - Increases
• D. Feature/organ - Intestinal PeristalsisSympathetic neural system - StimulatesParasympathetic neural system - Inhibits

Answer 1

Answer: (B)

Feature/organ - Pupil of the eye

Sympathetic neural system - Dilates

Parasympathetic neural system - Constricts

The correct matches are;

1. Feature/organ - Salivary glands

Sympathetic neural system - Inhibits secretion

Parasympathetic neural system - Stimulates secretion

2. Feature/organ - Pupil of the eye

Sympathetic neural system - Dilates

Parasympathetic neural system - Constricts

3. Feature/organ - Heart rate

Sympathetic neural system - Increases

Parasympathetic neural system - Decreases

4. Feature/organ - Intestinal Peristalsis

Sympathetic neural system - Inhibits

Parasympathetic neural system - Stimulates

So the correct option is 'B'.
