Question

As compared to sympathetic nervous system parasympathetic nervous system

• A. Dilates pupil
• B. Causes goose bumps
• C. Inhibits salivation
• D. Contracts urinary bladder

Answer 1

The correct option is D Contracts urinary bladder

The sympathetic nervous system is activated during an emergency situation which causes the blood flow to be diverted towards the skeletal system to prepare the body for the emergency situation and decreases the activity of the digestive, and urinary system. So sympathetic nervous system causes the dilation of pupil, goosebumps, inhibits salivation and relaxes the bladder. The parasympathetic nervous system does the opposite to this, therefore causing contraction of the urinary bladder. So the correct option is 'contracts urinary bladder'
