Sympathetic Nerves "Fight or Flight", facititate mobilization of the body for quick action
Parasympathetic Nerves "Feed and Breed", direct restoratice and conserative processes
Direct Acting receptor agonists which minic the effects of endogenous chemicals by combining with receptors in the sympathetic nervous system, nasal decongestant
Indirect Acting Facilitate the release of Norepinephrine or block the re-uptake of Norepinephrine in the neuronal membrane
Sympatholytic (Adrenergic Blocking) Agents Oppose the action of the natural messangers, epinephrine and Norepinephrine, as their receptor sites, also referred to as blockers
Parasympathomimetics (Cholinergic) Agents Enhance the actions of the parasympathetic nervous system, opposes the effects of the sympathetic nervous system, may be direct action on cholinergic receptors
Parasympatholytic (Anticholinergic) Agents Inhibit or reverse the actions of the parasympathetic nervous system, bind with the cholinergic receptors and prevent binding or acetylcholine
Neuromuscular Blocking Agents Blocks the transmisson of nerve impulses to skeletal muscles resulting in paralysis of skeletal muscle
Local Anesthetics Block conduction of impulses along nerves and prevents the sensation of pain from reaching the brain
Sympathomimetic Agents The effects of these agents are complex and depend upon the specific receptor where the drugs exert their action
