Show Hint

- Heart beat.
- Arterial blood pressure.
- Bronchi dilation.
- Micturition.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
The sympathetic nervous system prepares the body for emergency, the fight or flight response.
Step 2: Its actions
It increases heart rate, raises arterial blood pressure and dilates the bronchi so that more air enters the lungs.
Step 3: Micturition
The sympathetic system relaxes the bladder wall and contracts the internal sphincter, so it inhibits urination. Micturition is brought about by parasympathetic stimulation.
Final Answer:
Micturition is not stimulated by the sympathetic system. \[ \boxed{\text{(D) }\text{Micturition.}} \]
