from The American Heritage® Dictionary of the English Language, 4th Edition

  • n. A site in the autonomic nervous system in which excitatory responses occur when adrenergic agents, such as norepinephrine and epinephrine, are released. Activation of alpha-receptors causes various physiological reactions, including the stimulation of associated muscles and the constriction of blood vessels. Also called alpha-adrenergic receptor.


Sorry, no etymologies found.


  • I was convinced that the histamine antagonists of the day were analogous to the alpha-receptor antagonists and that the equivalent of a beta-receptor antagonist was needed to block, for example, histamine-stimulated acid secretion.
