What do the parasympathetic and sympathetic nervous systems share in common?

What do the parasympathetic and sympathetic divisions have in common?

Answers: Most nerve fibers from both divisions innervate many of the same effectors.

Most nerve fibers from both divisions share the same sites of origin.

The preganglionic nerve fibers in both divisions are of similar length.

The ganglia from both divisions are located in or near visceral organs.Most nerve fibers from both divisions innervate many of the same effectors.

Answers: The sympathetic and parasympathetic divisions both innervate many common smooth muscles, organs, and glands.

Most preganglionic fibers of the parasympathetic system arise from which nerve pair?

vagus

oculomotor
splanchnic
glossopharyngealvagus

The heart, lung, liver, gallbladder, pancreas, stomach, and intestines--virtually all of the visceral organs of the thoracic and abdominal cavities--contain ganglia innervated by nerve fibers from the vagus nerves.

A normal response to sympathetic nervous system activation would most likely include the .

inhibition of digestive system activity

decrease in heart rate
increased uptake of glucose from the blood
constriction of bronchiolesinhibition of digestive system activity

When in an emergency situation, digestion is not a critical body function.

Which structure or organ is innervated exclusively by sympathetic fibers?

iris
arrector pili muscles
gallbladder
heart arrector pili muscles

Arrector pili muscles in the skin are innervated by sympathetic fibers but not parasympathetic fibers.
