Prostaglandin: One of a number of hormone-like substances that participate in a wide range of body functions such as the contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels, control of blood pressure, and modulation of inflammation.
Release of these enzymes results in production of prostaglandins, with consequent induction of pain. High concentrations of prostaglandins cause pain by direct action upon nerve endings. More typically, however, at low concentrations, they markedly increase sensitivity to pain.The pain threshold may be so altered that even normally painless stimuli may be painful.here are many steps involved in conversion of the fatty acids to prostaglandins. Prostaglandins are not only synthesized when tissues are injured, but are ubiquitous throughout the body. They are not stored but are synthesized upon need.
