Which of these effects on digestion is not produced by the parasympathetic nervous system?
A
Increased salivation
B
Increased secretion of digestive enzymes
C
Relaxation of the sphincters
D
Decreased gastric motility
Verified step by step guidance1
Understand the role of the parasympathetic nervous system in digestion. It generally promotes activities that enhance digestion, such as increasing salivation and secretion of digestive enzymes.
Recognize that the parasympathetic nervous system is responsible for 'rest and digest' functions, which include increasing gastric motility to facilitate the movement of food through the digestive tract.
Identify the effects listed in the problem: increased salivation, increased secretion of digestive enzymes, relaxation of the sphincters, and decreased gastric motility.
Analyze each effect: Increased salivation and increased secretion of digestive enzymes are typical parasympathetic responses. Relaxation of sphincters is also a parasympathetic effect to allow passage of food.
Determine which effect is not typical of the parasympathetic nervous system. Decreased gastric motility contradicts the parasympathetic function, as it usually increases motility to aid digestion.
