EricksonNorahAutonomicNervousSystem
Sympathetic
Four E's- Exercise, excitement, embarrassment, emergency
Thoracic-lumbar
Pre-ganglionic neuron - short, before ganglion
post-ganglionic - long, after ganglion
effector - acetocholine - smooth muscle, cardiovascular muscle, glands
Heart
increase heart rate, increase force of contraction
airway/lungs
dilate bronchioles
GI tract
decrease activity in glands and smooth muscle, constrict sphincters
Accessory digestive organs
liver- increase release of glucose
Salivary Glands-decrease production
iris
dilate pupil
lens
distance vision
blood vessels
constrict most (skin, organs, extremities) blood vessels, increase blood pressure, dilate bv to brain, skeletal muscle, heart
sweat glands
active
Arrector pilli
active
Adrenal glands
release epinephrine
Parasympathetic
Rest and Digest
Cranial-Sacral
pre-ganglionic neuron - long, before ganglion
post-ganglionic neuron - short, after ganglion
Effector - norepenepherine, and acetocholine - smooth muscle, cardiac muscle, glands
Heart
decrease heart rate
airway/lungs
constrict bronchioles
GI tract
opposite of sympathetic, relax sphincters
Accessory digestive organs
liver- no effect, salivary glands- increase production
iris
constrict pupil
lens
near vision
blood vessels
little to no effect, coronary blood vessel constriction
sweat glands
no effect
arrector pilli
no effect
