This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Physiology
A research physiologist is performing an experiment in which he stimulates sympathetic cholinergic neurons. Which of the following responses is expected? 
Select and explain. 
A. Bradycardia, B. Bronchoconstriction, C. Diaphoresis, D. Increased gastrointestinal motility
C: Diaphoresis
Answer: C: Diaphoresis 
Explanation: The vast majority of sweat glands in the body are innervated by sympathetic cholinergic neurons. Sympathetic cholinergic neurons are sympathetic postganglionic neurons that happen to release acetylcholine instead of norepinephrine. Bradycardia, bronchoconstriction, and increased gastrointestinal motility would all result from stimulating parasympathetic cholinergic neurons.
