The parasympathetic innervation of the thoracic and abdominal cavities is through the:
vagus nerve
Will the innervation of the thoracic cavity, via the vagus nerve, have an inhibitory or excitatory effect?
inhibitory
What kind of effect will vagus nerve innervation have on the addominal cavity?
excitatory
Innervation through the sacral spinal cord stimulates the:
pelvic cavity
List two physical responses to innervation of the pelvic cavity via the sacral spinal cord.
urine activity
increased blood flow to the reproductive system
Which type of drug will bind to a receptor site and have the opposite effect of a neurotransmitter?
antagonist
Which type of drug will bind to a receptor and mimic the effect of a neurotransmitter?
agonist
Which type of drug will bind to a receptor site and prevent a neurotransmitter from binding?
blocker
The neurotransmitter released by parasympathetic preganglionic and postganglionic fibers is:
acetylcholine
What type of receptor is on the parasympathetic postganglionic neuron?
nicotinic receptor
What happens when acetylcholine binds to a nicotinic receptor?
sodium channels open causing the postganglionic neuron to depolarize
What class of receptor is on the target tissue in the parasympathetic division?
muscarinic receptor
What does the muscarinic receptor effect?
potassium permeability
If potassium leaves the target tissue it will begin to:
repolarize
Plant toxins, such as those in the deadly nightshade mushroom, can bind to which type of receptor?
muscarinic
