beta and alpha receptors|20. Actions of the Autonomic Nervous System: Adrenergic : Tagatay Distinct subtypes of β-adrenergic receptor exist and have important pharmacological consequences. β 1-Adrenergic receptors predominate in the heart and in the cerebral cortex, whereas β 2-adrenergic receptors predominate in the lung and cerebellum.

beta and alpha receptors,
The main difference between alpha and beta receptors is that alpha receptors stimulate the effector cells whereas beta receptors relax the effector cells. The two main types of alpha receptors are alpha 1 and alpha 2 receptors.There are two main groups of adrenoreceptors, α and β, with 9 subtypes in total: β receptors are subdivided into β 1, β 2 and β 3. All 3 are coupled to G s proteins, but β 2 and β 3 also couple to G i[7] G i and G s are linked to adenylyl cyclase.
There are two main groups of adrenergic receptors, α and β, with several subtypes. α receptors have the subtypes α1 (a Gq coupled receptor) and α2 (a Gi coupled receptor). Phenylephrine is a selective agonist of the α receptor. β-receptors have the subtypes β1, β2, and β3.
Alpha and beta receptors are types of adrenergic receptors in the autonomic nervous system that respond to catecholamines like norepinephrine and epinephrine. Alpha receptors (primarily.

Alpha receptors (primarily. Beta-1 receptors, along with beta-2, alpha-1, and alpha-2 receptors, are adrenergic receptors primarily responsible for signaling in the sympathetic nervous system. Beta-agonists bind to the beta receptors on various tissues throughout the body.Distinct subtypes of β-adrenergic receptor exist and have important pharmacological consequences. β 1-Adrenergic receptors predominate in the heart and in the cerebral cortex, whereas β 2-adrenergic receptors predominate in the lung and cerebellum.
While alpha and beta receptors both work to aid in the fight or flight response, they do so in opposing ways. Alpha receptors cause muscle contraction and vasoconstriction in certain body.
Beta receptors, subdivided into β1, β2, and β3, regulate heart rate, bronchodilation, and glycogenolysis. Alpha receptors are responsible for vasoconstriction and increasing blood pressure, while beta receptors are responsible for vasodilation and decreasing blood pressure.
