The figure illustrates the parasympathetic division. What does "A" represent?

cranial nerves
The figure illustrates the parasympathetic division. What does "C" represent?

terminal ganglia
The figure illustrates the parasympathetic division. What does "E" represent?

pelvic nerves parasympathetic effects more localized increases activity of GI tract effects are short-lived provides more extensive innervation of G.I. Tract craniosacral division functions at rest

sympathetic effects are more general can produce widespread sweating has greater influence during physical activity inhibits heart rate but stimulates contraction of urinary bladder stimulation of this system often activates many effectors at the same time release of epinephrine and norepinephrine thoracolumbar division fight-or-flight response provides innervation to blood vessels in skeletal muscles

The celiac ganglion is one of the three main _________ ganglia.

collateral
Axons from preganglionic neurons of the parasympathetic division synapse with _________ ganglia.

terminal
In the sympathetic division of the ANS,

the preganglionic cell body is located in the lateral horn of the spinal cord.
The parasympathetic nervous system is characterized by

short postganglionic axons near the organs they innervate.
The sympathetic and parasympathetic divisions of the ANS differ in the

length of the preganglionic and postganglionic axons, location of the preganglionic cell bodies, and position of the ganglia where preganglionic and postganglionic neurons synapse.
Sympathetic fibers leave the spinal cord in the

thoracic and lumbar regions.
Axons exit the sympathetic chain ganglia by all of the following except

cranial nerves.
Sympathetic preganglionic axons

can synapse in either chain or collateral ganglia.
Sympathetic stimulation of the postganglionic cells of the adrenal medulla causes the release of

epinephrine and norepinephrine.
The vagus nerve carries parasympathetic impulses to the

thoracic
