are a class of G-protein coupled receptors (GPCRs) that mediate the actions of catecholamines like norepinephrine and epinephrine in the sympathetic nervous system. They are broadly divided into two families, α1alpha sub 1 α2alpha sub 2

Recent studies highlight complex roles for alpha receptors beyond simple muscle contraction: : α1Aalpha sub 1 cap A end-sub alpha-adrenoceptor
