Pharm Flashcards
What is the major NT of the parasympathetic? What are its exceptions
ACh; it innervates adrenal medulla directly and also affects sweat glands
What is the precursor to epi and NE
Tyrosine->dopa->dopamine
Where is tyrosine converted to dopa and dopamine
Nerve cytoplasm
Where does dopamine -> NE -> epi
Within vessicles
What synthesizes ACh
ChAT
What inhibits ACh from being put in vessicles
Vesamicol through the ACh Co-T
What affects ACh release
VAMPS and SNAPS
What affects ACh destruction
Acetylcholinesterase on the effector cell membrane
What does botulinum toxin interact with
ACh release
What blocks reuptake of NE
Cocaine by way of NET (NE transporter)
What moves NE, Epi, DA, and serotonin into vesicles
VMAT2
What signaling method is used by all adrenergic receptors
GPCR
SM of blood vessels (IS/IS NOT) innervated by parasympathetic neruons
IS NOT
What must be intact for parasympathetic release of ACh to relax vessels
Endothelium
What breaks down catecholamines in cells
MAO and COMT
