adrenergic receptors. Definition: reactive components of effector tissues, most of which are innervated by adrenergic postganglionic fibers of the sympathetic nervous system.
adrenergic r's receptors for epinephrine or norepinephrine, such as those on effector organs innervated by postganglionic adrenergic fibers of the sympathetic nervous system. There are two types, alpha-adrenergic receptors and beta-adrenergic receptors.alpha r's (alpha-adrenergic r's) adrenergic receptors found in cardiac muscle and vascular smooth muscle; they are stimulated by norepinephrine and blocked by agents such as phenoxybenzamine.here are two types, alpha-adrenergic receptors and beta-adrenergic receptors. alpha r's (alpha-adrenergic r's) adrenergic receptors found in cardiac muscle and vascular smooth muscle; they are stimulated by norepinephrine and blocked by agents such as phenoxybenzamine.
