PANS
SANS
Medications
Preganglionic Neuron
Made of cholinergic fibers
Postganglionic Neuron
Made of adrenergic fibers
Releases norepinephrine
Releases acetylcholine
Pupil dilation
Increased heart rate
Signs/Symptoms of Stimulation
Short
Long
Bronchodilation
Relaxed bladder and uterus
Sweating
Sympatholytic
Sympathomimetic
Responds to stressful situations
Stimulates fight/flight response
Increased blood glucose
Decreased saliva
Slow GI motility
Increased blood pressure
Signs/Symptoms of Stimulation
Medications
Parasympathomimetic
Parasympatholytic
acts as an anti-agrenergic
Blocks SANS
Ex; beta blocker = slows heart rate
acts as an adrenergic agent
Mimics the sympathetic response
Ex; Epinephrine = stimulates heart rate and increases BP
acts as an anti-cholinergic agent
Blocks PANS
Ex; Scopolomine - motion sickness
Acts as a cholenergic agent
Mimics the parasympathetic response
Ex; NIcotine- used to quit smoking
decreases heart rate
contracts bronchials
increase in saliva
contraction of pupils
