Describe the physiological role of prostaglandins on smooth muscle throughout the body.
You may think this is an obscure question, however a group of drugs we use commonly (NSAIDS in case you were wondering) effectively counteract the physiological effects of these autacoids.
Vallecula recently posted on prostaglandins if you would like to review some more statements
Interestingly Katzung’s Basic and Clinical Pharmacology has a very good chapter (Chapter 18) discussing, amongst other things, prostaglandins.
BT_PO 1.89 Outline the physiological effects of prostaglandins and other autacoids
PGF2α causes contraction of uterine muscle, but relaxation of bronchial smooth muscle T/F
Prostaglandins generally cause contraction of GIT smooth muscle T/F
Prostacyclin, PGI2, causes vasodilation of arterioles through the release of nitric oxide T/F
Thromboxane mediates vascular smooth muscle contraction via increasing intracellular calcium levels T/F
PGF2α is a potent constrictor of the pulmonary vasculature, contraindicating its use intravenously T/F
