Parasympathetic ganglion
Terminal ganglia
Where is terminal ganglia located?
Effector
Where are sympathetic chain (vertebral) ganglia located?
Sides of vetebral column
Where are collateral (pre-vertebral) ganglia located?
Anterior to vetebral columns
Axon terminals of all preganglionic neurons release what chemical?
Acetylcholine
What transmits impulses across autonomic synapses?
Acetylcholine
Axon terminals of ______________ _______________ neurons release acetylcholine into their neuroeffector junctions.
POSTganglionic PARAsympathetic
only axon terminals that release norepinephrine:
SYMpathetic POSTganglionic neurons
Cholinergic fibers are axons whose terminals release?
Acetylcholine (ACh)
Adrenergic fibers are axons that release?
Norepinephrine
Classification of all PREganglionic and PARAsympathetic POSTganglionic fibers:
Cholinergic fibers
only POSTganglionic SYMpathetic fibers are known as:
Adrenergic
POSTganglionic SYMpathetic fibers release this chemical transmitter:
Norepinephrine
Cholinergic and adrenergic responded by the same effector are?
Antagonistic
Diarrhea is an example of a
PARAsympathetic response
Regulates responses of visceral effectors that tend to enable body to expend maximal energy.
SYMpathetic nervous system

Would
A drug that inhibits the PARAsympathetic system would or would not construct your pupils?
Would not
A drug that inhibits the PARAsympathetic system would or would not make your heart beat faster?
Would
A drug that inhibits the PARAsympathetic system would or would not tend to make you constipated?
Would
What division of the ANS is responsible for the rest and repose (maintenance) response of the body?
PARAsympathetic
Division of ANS that has a general effect on entire body at one time?
