- 1anatomical differences between the sympathetic and parasympathetic nervous system1. sites of origin
2. relative lengths of their fibers
3. location of their ganglia - 2sympathetic nervous system fiber lengthSHORT pre-synaptic and
LONG post-synaptic - 3parasympathetic nervous system fiber lengthLONG pre-synaptic and
SHORT post-synaptic - 4what type of nerve fiber are presynaptic nervestype B (lightly myelinated)
- 5what type of nerve fiber are postsynaptic nervestype C (nonmyelinated)
- 6neurotransmitters that the sympathetic nervous system utilizesutilizes ACh at ganglion synapses and norepinephrine at terminal components
- 7neurotransmitters that the parasympathetic nervous system utilizesutilizes ACh at both the ganglion synapses and terminal components
- 8goal of the sympathetic nervous systemprepare the body for intense physical activity
- 9site of origin SNSlateral horns of T1-L2
- 10location of ganglia SNSsympathetic chain (trunk) and abdominal aorta
- 11sympathetic targets-pupil dilation
-decrease saliva production
-increase HR
-increase respiration (bronchodilator)
-decrease digestion
-secrete norepinephrine & epinephrine
-decrease urination
-promote ejaculation & vaginal contractions - 12goal of the parasympathetic nervous systemrelax the body and inhibit/slow many high energy functions & ramp up digestive functions
- 13site of origin of PSNSbrain stem (CN III, VII, IX, X) and sacral region (S2-4)
- 14location of ganglia PSNSnear the target organ
- 15parasympathetic targets-pupil constriction
-increase saliva production
-increase tear production
-decrease HR
-decrease respiration (bronchoconstriction)
-increase digestion
-increase urination
-promote erection of genitalia - 16who is in control of the sympathetic & parasympathetic nervous systemsympathetic = posterior hypothalamus
parasympathetic = anterior hypothalamus - 17what the hypothalamus controls4 F's:
