A site in the autonomic nervous system in which inhibitory responses occur when adrenergic agents, such as norepinephrine and epinephrine, are released. Activation of beta-receptors causes various physiological reactions, such as relaxation of the bronchial muscles and an increase in the rate and force of cardiac contraction. Also called beta-adrenergic receptor.beta-receptor
