Cards

Term
Ouabain
Definition
NA/K ATPase (used for heart failure and volume regualtion)
Term
Omeprazole
Definition
H+/K+ ATPase (acid secretion in stomach)
Term
Tetrodotoxin/ Saxitoxin/ cocaine/ lidocaine
Definition
(fast) NA+ channels / blocks formation of APs
Term
Tetraethylammonium
Definition
K+ channel
Term
Achesterase symptoms
Definition
SLUD
Term
dendrotoxin
Definition
blocks some K+ channels, not ALL...causes the shakes
Term
omega conotoxin
Definition
blocks voltage gated Ca channel, which block secretion of NTs from vesicles...doesn't block APs
Term
botulinum toxin
Definition
endopeptidase that breaks down vesicular fusion proteins, can't release APs: FLACID PARALYSIS
Term
tetanus toxin
Definition
endopeptidase that breaks down vesic fusion proteins. inhibits GLY release= SPASTIC PARALYSIS
Term
Atropine
Definition
muscarinic receptor blocker, dilates pupils
Term
Curare
Definition
Nicotinic receptor blocker, current derivatives are succ choline & pancurium, DIAPHRAGM PARALYZER
Term
What inhibits Thromboxane?
Definition
Nitric Oxide
Term
alpha bungarotoxin (irr)
d-Tubocurarine, pancuronium (rev)
Definition
inhibits Nicotinic Ach Receptor
Term
Succinylcholine
Definition
agonist (activator/ depolarizer) of nicotinic Ach receptor
Term
propranonol
Definition
beta andrenergic inh
Term
hexamethonium
Definition
cnicotinic-cholinergic inh
Term
digitalis
Definition
inhibits NA/CA excahnger
Term
phospholamban
Definition
increases SERCA activity
Term
protein kinase A (cardiac related)
Definition
activates L type Ca channels and phospholamban, which increases SERCA activity, INCREASED HEART CONTRACTION
