sodium channel inactivation
Give this one a try later!
Na channel activates to open: -70mV
-carry in large current to depolarize cell
-inactivate quickly--while inactive Na+ channel cannot activate at or above
threshold potential
-Na channel undergo fast inactivation by inactivation gate
-Na+ channels undergo slow inactivation which involves conformation
change
hyperlipidemia
Give this one a try later!
, an increase in plasma lipids in general
leukotriene modifiers
Give this one a try later!
-released by mast cells (mostly) within minutes
-LTs more potent bronchoconstrictors than histamine and longer duration
of action
---inhibit leukotriene synthesis
---direct leukotriene 4 receptor antagonist
large veins
Give this one a try later!
larger than 10mm in diameter
-smooth muscle from all three tunics
-thin media with moderate smooth muscle
-venae cavae, pulmonary veins, internal jugular veins, renal veins
-tunica externa is the thickest layer

serum potassium (diuretics cause hypokalemia)
hypercalcemia (calcium and digoxin have ionotropic effects)
