receptor sites for the sympathetic neurotransmitters norepinephrine and epinephrine
a class of adrenergic receptors that are further subdivided into alpha 1 and alpha 2 and are differentiated by anatomic location
bodily functions that are involuntary and result from the physiologic activity of the ANS, functions often occur in pairs of opposing actions
autonomic nervous system
a branch of the peripheral nervous system that controls autonomic bodily functions
beta 2 adrenergic receptors
located primarily in the smooth muscle fibers of bronchioles and viseral organs
a third type of adrenergic receptor in addition to alpha and beta and activated by binding of neurotransmitter dopamine
positive dromotropic effect
an increase in the conduction of cardiac electrical impulses through the AV node
space between adjacent nerve cells or the nerve cell membrane and an effector organ cell membrane
drugs that bind to specific receptors and inhibit or block the response of the receptors
acetylcholine-needed for normal brain function
neurotransmitter responsible for transmission of nerve impulses to effector cells in the PNS
cholinergic receptors that are located postsynaptically in the effector organs such as smooth muscle
urecholine-direct acting cholinergic agonist should be taken with meals to avoid GI upset, contraindicated with peptic ulcer
parasympatholytics,cholinergic blockers, anticholinergics-contraindicated with BPH
vasoconstriction and central nervous system stimulation
predominant alpha adrenergic agonist response
beta 2 selective adrenergic drugs include
albuterol, ephedrine, formoterol,levalbuterol,metaproterenol, pirbuterol, salmeterol and terbutaline
used to treat infiltration of adrenergic drugs by causing localized vasodilation
