The axon terminals of all preganglionic neurons release this chemical, which transmits impulses across autonomic synapses.
The axon terminals of all (or almost all) of these neurons release acetylcholine into their neuroeffector junctions:
All preganglionic fibers and all parasympathetic postganglionic fibers are classified as:
Postganglionic sympathetic fibers are the only fibers known definitely to be classified as this:
The chemical transmitter presumably released only by postganglionic sympathetic fibers is:
which of the following could be correctly described as a parasympathetic response: an increase in the pulse rate? Diarrhea resulting from increase peristalsis? High blood pressure?
The general function of this division of the ANS is to regulate the responses of visceral effectors in ways that tend to enable the body to expend maximal energy.
Would make your mouth feel dry , would not constrict your pupils, would make your heart beat faster, would tend to make you constipated.
A drug that inhibits the parasympathetic system would/would not make your mouth feel dry? would/would not constrict your pupils? would/would not make your heart beat faster? would/would not tend to make you constipated?
A.) Terminal, B.) Near or in the tissue organ
The parasympathetic division of the ANS has one type of ganglia. A.) What is the name of the parasympathetic gangion? B.) Where is this type of ganglia located?
A.) Both side of the vertebrae, B.) Anterior to vertebral bodies
The sympathetic division of the ANS has two types of ganglia. A.) Where are the sympathetic chain (vertebral) ganglia located? B.) Where are the collateral (pre-vertebral ganglia located?

A.) III, VII, IX, X B.) 0 C.)0 D.) Sympathetic Nerves
The terms "thoracolumbar" and "craniosacral" are based on the fact that neurons of the ANS exit the Central Nervous System in specific locations. A.) What cranial nerves contribute the the parasympathetic division of the ANS? B.) What cranial nerves contribute to the sympathetic division of the ANS? C.) What spinal nerves contribute to the parasympathetic division of the ANS? D.) What spinal nerves contribute to the sympathetic division of the ANS?
This division of the ANS is responsible for the rest and repose (maintenance) response of the body.
A.) Parasympathetic B.) Sympathetic C.) Sympathetic D.) Parasympathetic
The location of the ANS ganglia affects the length of the pre-ganglionic and post-ganglionic neurons of each division. A.) Which division have relatively long pre-ganglionic neurons? B.) Which division have relatively short pre-ganglionic neurons? C.) Which division have relatively long post-ganglionic neurons? D.) Which division have relatively short post-ganglionic neurons?
