Lec 16 Peripheral Circulation Flashcards
complex that phosphorylates myosin
calcium, calmodulin, myosin light chain kinase
attaching phosphate to myosin requires blank
atp
two ways to regulate smooth muscle
amount of calcium, amount of myosin light chain kinase
only way to regulate skeletal muscle
amount of calcium
regulating smooth muscle is a more blank process than regulating skeletal muscle
complex
sympathetic norepinephrine causes blank of smooth muscle
contraction
hyperpolarization causes blank of smooth muscle
relaxation
local control of nutritive blood flow to tissue
active hyperemia
vasodilation blank resistance and blank flow
decreases, increases
sympathetic stimulation of postcapillary alpha 1 causes these
decrease venous compliance
increase venous pressure
decrease venous volume
sympathetic stimulation of precapillary alpha 1 causes these
increased arteriolar resistance
decreased arteriolar flow
goal of sympathetic stimulation is to get blood out of blank circulation and get it into blank circulation to keep you alive
peripheral, central
the reason epinephrine in circulation will cause relaxation and thus vasodilation, is because it increases local blank
metabolism
increased metabolism causes stimulation of these receptors thus causing vasodilation
beta 2
when sympathetic stimulates alpha 1 receptors, blank occurs
vasoconstriction
