In contrast to the sympathetic nervous system, the functions of the parasympathetic nervous system include:

A) Sweating: Sweating is a function of the sympathetic nervous system, not the parasympathetic nervous system. The sympathetic nervous system is responsible for the "fight or flight" response, which includes activating sweat glands. The parasympathetic system, in contrast, is more involved in "rest and digest" functions. B) Pupil dilation: Pupil dilation (mydriasis) is mediated by the sympathetic nervous system through the activation of alpha-1 adrenergic receptors. The parasympathetic system causes pupil constriction (miosis) by stimulating muscarinic receptors in the eye, which is the opposite of pupil dilation. C) Vasoconstriction: Vasoconstriction (narrowing of blood vessels) is generally a function of the sympathetic nervous system, which releases norepinephrine to constrict blood vessels and increase blood pressure. The parasympathetic system typically causes vasodilation (widening of blood vessels) to promote relaxation and decreased blood pressure. D) Anabolism: Anabolism refers to the metabolic processes that build up molecules and store energy, such as protein synthesis, cell growth, and energy storage. This is primarily mediated by the parasympathetic nervous system, which is involved in "rest and digest" functions. The parasympathetic system promotes activities that support energy conservation, digestion, and tissue repair, all of which support anabolic processes.
