white ramus

25
Q

axons of postganglionic fibers (unmyelinated) from the point where they leave the sympathetic chain to the point where they enter the ventral root

A

gray ramus

26
Q

places of exit from CNS: brain and sacral region of spinal cord (craniosacral nervous system)
functions: conservation and storage of bodily resources, active after eating
contains preganglionic and postganglionic fibers,

A

parasympathetic nervous system

27
Q

goes form brain or spinal cord (lateral horn) to a collateral ganglion, relatively long, secretes acetylcholine

preganglionic fiber from parasympathetic nervous system

28
Q

goes from collateral ganglion to the organ to be innervated, relatively short, secretes acetylcholine

A

postganglionic fiber from parasympathetic nervous system

29
Q

circulatory:
causes heart to beat faster, constricts surface arteries and raises blood pressure, dilates blood vessels to skeletal muscles, speeds clotting

A

sympathetic NS effects on circulatory system

30

34
Q

digestive: facilitates peristalsis of stomach and small intestine, facilitates gastric secretion, facilitates secretion of saliva

A

effects of parasympathetic NS on digestive system

35
Q

urinary genital:
inhibits action of bladder (relaxing muscle wall), vasoconstriction in kidney leading to decreased urine, contracts uterus

A

effects of sympathetic NS on urinary genital

36
Q

urinary genital:
facilitates action of bladder (muscle wall contracted), vasodilation in kidney leading to increased urine flow, relaxes uterus
