ANS CPR

Question 1

majority of parasympathetics n source and receptors are?

Answer 1

vagus, muscarinic

Question 2

upper airways are supplied by what n and ganglion for parasympathetic?

Answer 2

trigeminal nerve, sphenopalatine ganglion

vasodilation, increase secretion of mucus

Question 3

sympathetics for sweat glands are different how?

Answer 3

muscarinic receptors, relax smooth m = vasodilation = increase sweat

Question 4

SA node sympathetics and parasympathetics?

Answer 4

s - beta 1
increase rate of depolarization and HR

p - decrease rate of depolarization and HR

Question 5

AV node sympathetics and parasympathetics?

Answer 5

s - beta 1
inc rate of depolarization during phase 0, increase conduction velocity and rate

p - dec slope pacemaker potential, dec depolarizaton rate during phase 0, decrease conduction v in av/ventricles and dec vent rate

Question 6

myocytes sympathetics and parasympathetics?

Answer 6

s - Beta 1/2
increase ca conductance -> myocyte contractility

p oppo

Question 7

cerebral vasculature

Answer 7

s - alpha 1
contraction of smooth m, vasoconstriction when bp too high
constriction of small arteries

Question 8

coronary arteries sympathetics and parasympathetics?

Answer 8

s - alpha 1
smooth m contraction, vasoconstrict, decrease blood flow

p - smooth m relax, vasodilation, increase coronary blood flow

Question 9

cutaneous vasculature sympathetics and parasympathetics?

Answer 9

s - alpha 1
contraction vascular smooth m, vasoconstriction

NO PARASYMPATHETICS

Question 10

skeletal m sympathetics and parasympathetics?

Answer 10

s = alpha 1 - contraction of vas smooth m, vasoconstrict
beta2 - relaxation of vsm, vasodilate blood supply to m

p = relaxation of vsm, vasodilation, some say increase NO release, vasodilated

Question 11

splanchnic

Answer 11

sympathetic only
t5-l2
geliac, sup mesnteric, inferior mesnetric ganglion
alpha 1
contraction of vas smooth m, vasoconstrict

Question 12

innervation of veins

Answer 12

alpha 1 - contraction of venous sm, increase blood return to heart
alpha 2 - relax venous sm, dilation veins, slow return to heart
beta 2 - relax venous sm, dilation veins, slow return to heart

Question 13

extrapulmonary arteries sympathetics and parasympathetics?

Answer 13

s - 1st 5 thoracic ganglia
alpha 1 - contract vascular smooth m, vasoconstriction of vessels
beta 1/2 -relax vas smooth m, vasodilation

p - nucleus ambiguus, vasodilation, produce NO, release it from endothelial cells, relaxation of vasc smooth m

Question 14

upper airways sympathetic?

Answer 14

s - alpha1

smooth m contraction, vasoconstriction, reduce mucus secretion

Question 15

lower airways sympathetics and parasympathetics?

Answer 15

s - T1-5, beta 2
relax bronchial smooth m, bronchodilation, increase bronchial secretions, but minor

p - contract bronchial smooth m, syn mucus, bronchoconstriction increased secretion

Question 16

vasculature of kidneys sym and parasym?

Answer 16

s - alpha
contraction of vascular smooth m, vasoconstriction of renal a/ a in kidney, afferent/efferent arteriole = decreases blood flow to kidney and urine production, preserves bp in rest of body

Question 17

juxtaglomerular, granule cells of afferent arteriole

Answer 17

s - beta 1

increase renin -> angiotension->ang 2-> aldosterone -> reabsorb NA and ADH to reabsorb water -> increase blood volume
