Alpha-1 adrenergic receptor - Wikipediahttps://en.wikipedia.org/wiki/Alpha-1_adrenergic_receptorEffects. The α 1-adrenergic receptor has several general functions in common with the α 2-adrenergic receptor, but also has specific effects of its own. α1-receptors primarily mediate smooth muscle contraction, but have important functions elsewhere as well. The neurotransmitter norepinephrine has higher affinity for the α1 receptor than does epinephrine (which is a hormone).

Alpha-2 adrenergic receptor - Wikipediahttps://en.wikipedia.org/wiki/Alpha-2_adrenergic_receptorThe alpha-2 (α 2) adrenergic receptor (or adrenoceptor) is a G protein-coupled receptor (GPCR) associated with the G i heterotrimeric G-protein.It consists of three highly homologous subtypes, including α 2A-, α 2B-, and α 2C-adrenergic.Some species other than humans express a fourth α 2D-adrenergic receptor as well. Catecholamines like norepinephrine (noradrenaline) and epinephrine ...
