How do alpha adrenergic receptors work
WebAlpha-adrenergic receptors play an important role in the regulation of blood pressure (BP). …. They determine both arteriolar resistance and venous capacitance, and thus BP. Alpha 2 receptors are found both in the brain and in the periphery. In the brain stem, they modulate sympathetic outflow. WebIn fight-or-flight response. The receptors are known as alpha-adrenergic and beta-adrenergic receptors, or alpha receptors and beta receptors, respectively ( see human nervous system: Anatomy of the human nervous system). In general, activation of alpha-adrenergic receptors results in the constriction of blood vessels, contraction of uterine ...
