ANS Flashcards
Etiology of Myasthenia Gravis
Abs to Ach-R
Sx’s of Myasthenia Gravis
Ptosis, Diplopia that worsens throughout the day
Activation of a1-R =
SM contraction, Mydriasis, Increase bladder sphincter contraction
Activation of ß1-R =
Tachycardia, Increased lipolysis, Increased myocardial contractility, Increased renin release
Activation of ß2-R =
Vasodilation, Bronchodilation, Increased insulin release, Decreased uterine tone
What does Black widow spider toxin do at the nerve terminal
Stimulates Ach release
What does Botulinum do at the nerve terminal
Inhibits Ach release
What do Amphetamines, Ephedrine, and Tyramine do at the nerve terminal
Stimulate Nepi release
What do Cocaine and TCA’s do at the nerve terminal
Inhibit reuptake of Nepi
What does PGI2 do
Decrease platelet ag, vascular tone uterine contraction
What does PGF2 do
Increase uterine tone
What does PGE2 do
Increase uterine tone, decrease vascular tone
What do TXA’s do
Increase platelet ag, increase vascular tone
What do Bcl2 and BAX do
Bcl2 = cell lives; BAX = death (‘ax the cell’)
When does fetal movement being
