    agree. The sympathetic system is a fight or flight response so diaphoresis, tachycardia, GI shut down are all part of that.

    Excellent guys and gals.

    The correct answer is C. 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 (choice A), bronchoconstriction (choice B), and increased gastrointestinal motility (choice D) would all result from stimulating parasympathetic cholinergic neurons.

    Increased peripheral vascular resistance (choice E) would result from stimulating sympathetic adrenergic neurons.
