Adrenergic nerves

There are several types of adrenergic receptors which are identified by their differing sensitivities to various drugs. Neurons in the central nervous system contain α1- and α2-adrenergic receptors and β1- and β2-adrenergic receptors. All four kinds of receptors are also found in the various organs of the body aside from the brain. They are responsible for the effects of epinephrine and norepinephrine when they act as hormones outside the central nervous system. In the brain, all … WebAdrenergic activators are agonists that stimulate adrenergic receptors resulting in stimulation of the sympathetic nervous system (fight or flight). Adrenergic receptors are …
