QuestionAnswer
Which adrenergic receptor increases the force of heart contraction and BP and causes pupillary dilation (mydriasis) by blocking vasodilation and pupillary constriction (miosis) Alpha 1
Which adrenergic receptor inhibits release of norepinephrine, dilates blood vessels which results in hypotension Alpha 2
which adrenergic receptor increases HR and force of heart contraction by blocking the effect of decreasing HR Beta 1
Which adrenergic receptor dilates bronchioles and relaxes GI tract by blocking the constriction of bronchioles Beta 2
What drug treats anaphylactic shock, often the 1st drug given in CPR in attempt to reverse cardiac arrest? Epinephrine
What drug is an adrenergic that affects alpha 1 &2 receptors. Used mainly to increase BP Norepinephrine
What adrenergic drug is human label, affects beta-1 receptors and its action is dose dependent? Dopamine
What drug is used to treat canine urinary incontinence (PO BID) Phenylpropanolamine (PPA)
Are adrenergic agents apart of the sympathetic or parasympathetic response ? sympathetic

The axons carry electric impulses__ from the nerve cell away
The dendrites carry electric impulses __ the nerve cell towards
What is the chemical messenger of the nerve impulses that pass from the axon to another structure? neurotransmitter
What is the junction between the nerve ending and the adjacent structure? synapse
Alpha receptors are __ except ____ stimulatory, GI tract
Beta receptors are ___ except the ___ inhibitory, heart
