Question
Which is not an expected effect of stimulation of the parasympathetic nerve?Multiple choice question.Reduction in heart rateIncreased saliva secretionIncreased sweat gland secretionIncrease in digestive activity
Solution
The parasympathetic nervous system is part of the autonomic nervous system that conserves energy as it slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles in the gastrointestinal tract.
Here are the effects of the parasympathetic nerve stimulation:
-
Reduction in heart rate: The parasympathetic nervous system slows the heart rate when the body is in a relaxed state. So, this is an expected effect.
-
Increased saliva secretion: The parasympathetic nervous system stimulates the salivary glands to secrete more saliva during digestion. So, this is also an expected effect.
-
Increased sweat gland secretion: This is not an expected effect of parasympathetic nerve stimulation. The sympathetic nervous system, not the parasympathetic nervous system, is responsible for stimulating sweat gland secretion, especially during stress or high temperatures.
-
Increase in digestive activity: The parasympathetic nervous system increases the activity of the digestive system by stimulating the secretion of digestive enzymes and movement of the digestive tract. So, this is an expected effect.
So, the answer is "Increased sweat gland secretion" as it is not an expected effect of stimulation of the parasympathetic nerve.
