Question

Which one of the following is not an effect of sympathetic nervous system?

• A. Dilation of pupil
• B. Inhibition of peristalsis
• C. Elevation of blood pressure
• D. Stimulation for saliva secretion during digestion or eating

Answer 1

The correct option is D Stimulation for saliva secretion during digestion or eating

The sympathetic nervous system is involved in the stimulation of activities that prepare the body for action, such as increasing the heart rate, increasing the release of sugar from the liver into the blood, and other generally considered as fight-or-flight responses (responses that serve to fight off or retreat from danger).

The parasympathetic nervous system activates tranquil functions, such as stimulating the secretion of saliva or digestive enzymes into the stomach.
