This exhibit shows the autonomic nervous system involving the parasympathetic and sympathetic systems. The sympathetic system (norepinephrine) is responsible for reduced saliva flow, mydriasis, increased SV & HR, vasocontraction, and the inhibition of bladder contraction. The parasympathetic system (acetylcholine) is responsible for stimulated saliva flow, miosis, decreased HR, bronchoconstriction, stimulated bile release, and bladder contraction.
