Question

Which of the following is not the action of sympathetic nervous system?

• B. Storage of bile in the gall bladder
• C. Constriction of peripheral arteries
• D. Contraction in the wall of urinary bladder

Answer 1

Answer: (B)

Storage of bile in the gall bladder

The sympathetic nervous system (SNS) is one of the two main divisions of the autonomic nervous system, directs the body's rapid involuntary response to dangerous or stressful situations. For example, the sympathetic nervous system can accelerate heart rate; widen bronchial passages; decrease motility (movement) of the large intestine; constrict blood vessels; increase peristalsis in the oesophagus; cause pupillary dilation, piloerection (goosebumps) and perspiration (sweating); and raise blood pressure.

Storage of bile in the gallbladder is functioning by the parasympathetic nerve.

So, the correct option is B.
