Exam 15: The Autonomic Nervous System and Visceral Reflexes

In response to high blood pressure, stretch receptors called in the walls of arteries carrying blood to the head will trigger a reflex that causes the heart to its beats per minute.

Antagonistic effects of the two divisions of the autonomic nervous system are exemplified in the control of

Autonomic function receives input from all these except

This figure shows the neural pathway through the autonomic nervous system.What structure(s) is(are) not associated with the autonomic nervous system?

is an example of the cooperative effect between the two autonomic nervous system divisions.

These are all characteristics of the enteric nervous systems except

Both divisions of the autonomic nervous system are normally active simultaneously.

The is an especially important center of autonomic control.

Atropine is sometimes used to dilate the pupil for eye examination.Which receptor would atropine block?

The neurotransmitter(s) associated with autonomic ganglia is(are)

Drugs that are monoamine oxidase (MAO) inhibitors would most likely

This enzyme breaks down norepinephrine (NE).

All of the following are under dual control of the ANS except

Preganglionic fibers run from

Sympathetic nerve fibers are not associated with situations involving

All autonomic output originates in the central nervous system.

Propranolol, a beta-blocker, is typically used to

These are all characteristics of the parasympathetic division except

Which nerve(s) carries the most parasympathetic fibers?

Most preganglionic fibers synapse with postganglionic fibers in the dorsal root ganglia.
