    Adrenergic medications affect the four receptors‚ a1‚ a2‚ B1 and B2. The sympathetic nervous system triggers the secretion of epinephrine and norepinephrine. Epinephrine is a hormone and norepinephrine functions as a hormone and neurotransmitter. First we will take a look at the Alpha 1 receptors. These Alpha 1 receptors cause vasoconstriction of vascular smooth muscles. They are located on the post synaptic membranes of effector organs‚ such as on gastral and urinary sphincters. Some are located
