Question

Quizplus · Accepted Answer

The dry mouth response is caused by the sympathetic division of the autonomic nervous system, which reduces salivary gland secretion due to its role in the body's fight or flight response. This response is triggered in situations of stress or anxiety, such as when giving an oral presentation. Choice A is incorrect because acetylcholine stimulates salivary glands to produce more saliva. Choice C and D are incorrect because they do not play a role in regulating salivary gland secretion. Choice E is incorrect because the parasympathetic division of the autonomic nervous system stimulates salivary gland secretion.
