This hormone is distinguished from other catecholamines (caa-tuh-COHL-uh-meenz) by having a methyl (MEH- thihl) group attached to its nitrogen atom. The action of this hormone is diminished by beta-blockers, and though it is not glucagon (GLOO-kuh-gahn), its receptors in the liver work with adenylate cyclase (uh-DEHN-uh-layt SI-klays) to increase the concentration of cyclic AMP, resulting in the conversion of glycogen (GLI-koh-jehn) to glucose. Other effects of this hormone include the relaxation of smooth muscle and an increase in blood pressure, explaining why it is often administered to patients suffering from anap

Fa- mously mimicked by the herb ephedra (uh-FED-ruh), name this hormone that dilates air passages, contracts blood vessels, and increases heart rate, all as part of the fight-or-flight response.
