Prostaglandins have no role in

Options

(a) inflammatory and allergic reactions
(b) blood clotting
(c) smooth muscle contraction
(d) conduction of nerve impulses

Correct Answer:

conduction of nerve impulses

Explanation:

Prostaglandin is any of a group of organic compounds derived from essential fatty acids and causing a range of physiological effects in animals. Prostaglandins have been detected in most body tissues. They act at very low concentrations to cause the contraction of smooth muscle; natural and synthetic prostaglandin are used to induce abortion or labor in humans and domestic animals. Two prostaglandin derivatives have antagonistic effects on blood circulation: thromboxane A₂causes bolld clotting, while prostacyclin causes blood vessels to dilate. Prostaglandins are also involved in inflammation, being released from affected tissues.
