Question

Quizplus · Accepted Answer

Norepinephrine can stimulate both alpha and beta receptors in the body. The alpha receptors are further classified as alpha-1 and alpha-2, while the beta receptors are categorized as beta-1, beta-2, and beta-3. The effects of norepinephrine on these receptors depend on various factors such as the location of the receptor, the subtype of the receptor, and the concentration of norepinephrine. For example, stimulation of alpha-1 receptors can cause vasoconstriction, while activation of beta-2 receptors can cause bronchodilation.
