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
