Webα 2-Adrenergic agonists produce clinical effects after binding to α 2-adrenergic receptors, of which there are three subtypes (α 2A, α 2B, and α 2C).These receptor subtypes are distributed ubiquitously, and each may be uniquely responsible for some, but not all, of the actions of α 2 agonists; for example, the α 2B-adrenoceptor subtype mediates the short … Webreceptors are located in the medulla oblongata and respond to very low blood pressure in the brain (below 50 mm Hg). In response, specific vasomotor center receptors stimulate severe constriction of peripheral blood vessels and very intense heart rate increase in order to increase blood pressure. Thus, for a short period of time, ischemia
