    1/147

    CNS=brain and spinal cord

    Adrenergic system, think adrenaline.Neurotransmitter=norepinephrine

    Sympathomimetic= adrenergic agonist

    Fight or flight

    2/147

    Sympathetic Response

    Pupils Dilate

    Bronchodilation

    Tachycardia

    Blood vessel constriction

    Relaxation of GI system

    Bladder relaxes

    Parasympathetic System Cholinergic system

    Neurotransmitter=acetylcholine

    Cholinergic agonist

  • 8/8/2019 Med test 2

    4/147

    When cholinergic system is activated:

    Pupils constrict

    Bronchioles constrict

    Vessels dilate

    Decreased HR

    Increased peristalsis

    Increased Salivation

    To treat GERD, decrease nausea treats gastroparesis

    Because it makes things move thru the gastric systemquicker, faster gastric emptying.
