Which type of nerve fibers make up the autonomic nervous system (ANS)?

Where do sympathetic preganglionic fibers synapse?

Where are cell bodies of somatic motor neurons located?

Which region of the spinal cord does NOT contain any autonomic neurons?

The parasympathetic division of the autonomic nervous system (ANS) is characterized by __________.

Which of these statements accurately describes how the general visceral motor system of the autonomic nervous system (ANS) differs from the general somatic motor system?

Which of these statements accurately describes a similarity between the sympathetic and parasympathetic divisions of the ANS ?

The ANS is the system of __________ neurons that regulates such functions as __________.

Postganglionic sympathetic fibers to sweat glands and peripheral blood vessels secrete _________.

The general visceral motor division of the peripheral nervous system describes the

Cell body of this autonomic neuron lies outside the CNS.

Cell body of this autonomic neuron lies within the CNS.

Division that is dominant during exercise, excitement, or emergencies.

Which of these is not innervated by the ANS?

Another name for the ANS is the

Which of these descriptions is not a result of parasympathetic stimulation?

The trunk ganglia contain what kind of cell bodies?

Cell bodies of the preganglionic sympathetic neurons are located within the

Which autonomic division increases heart rate?

Preganglionic fibers are myelinated, whereas postganglionic fibers are unmyelinated.

Which cranial nerve carries parasympathetic innervation to the thoracic and abdominal viscera?

Which of these organs/tissues are NOT innervated by parasympathetic fibers, or do not exhibit parasympathetic effects?

Division of the ANS responsible for the fight-or-flight response describes the

Division of the ANS most active during vigorous exercise describes the

Division of the ANS most active when the body is at rest describes the

Which statement is true concerning the innervation of adrenal medulla?

Sympathetic innervation to the head follows which pathway?

If you were very nervous about speaking in front of a group of people, which of the following would be likely to develop?

What is the role of the gray rami communicantes?

The sympathetic pathways to the extremities, direct impulses to which of these structures/tissues?

Short nerve branches that connect the ventral rami of spinal nerves to the sympathetic ganglia.

Ganglia of this structure are connected to the ventral rami of spinal nerves through the rami communicantes.

Which division of the autonomic nervous system innervates the sweat glands in skin?

The gray and white rami communicantes attach to the

What stimulates the adrenal medulla to secrete its excitatory neurohormones?

Which of these statements concerning gray rami communicantes is incorrect?

Cell bodies of preganglionic sympathetic neurons are located within the

Identify the pathway that correctly traces the movement of preganglionic sympathetic fibers.

The secretions of the adrenal medulla act to supplement the effects of

Where would you not find an autonomic ganglion?

Sympathetic trunk ganglia contain the cell bodies of sensory neurons and are located in the dorsal root of the spinal cord.

Because the fibers of the sympathetic division arise from the thoracic and lumbar regions of the spinal cord, they cannot innervate structures of the head or pelvis.

Parasympathetic fibers innervate the sweat glands, arrector pili, and smooth muscles of the arteries. `

This division can also be called the craniosacral division.

Division that is dominant during rest, digestion, and excretion.

Which division of the autonomic nervous system has preganglionic fibers within the facial nerve?

All of the following have only sympathetic innervation except the

Which of the following cranial nerves does not supply parasympathetic fibers to the head?

The parasympathetic nervous system is characterized by

The site of origin of the preganglionic fibers of the parasympathetic nervous system is the

Cranial parasympathetic outflow is contained in all of the following cranial nerves except the

In which autonomic division do nerve cell bodies lie closest to the organs being innervated?

Parasympathetic postganglionic fibers of the head travel within the

Sympathetic fibers leave the spinal cord in the

Over 90% of all preganglionic parasympathetic fibers are in cranial nerve

What is the effect of parasympathetic stimulation of respiratory bronchioles in the lungs?

Parasympathetic stimulation of blood vessels causes vasoconstriction and increased blood pressure.

Fibers from the cranial and sacral regions of the spinal cord contribute to the sympathetic division.

Postganglionic sympathetic fibers are relatively long compared to those of the parasympathetic division.

The sympathetic and parasympathetic divisions can be distinguished by the amount of branching of the post-ganglionic fibers.

Referred pain from the small intestines would be felt in the __________, whereas referred pain from the liver would be felt in the __________.

Control of temperature, of autonomic nervous reflexes, of hunger, and of sleep are functions associated with the

The part of the brain that exerts more control over autonomic functioning than any other part is the

The overall integrating center for the ANS.

Stimulation of the vagus nerve in the baroreceptor reflex causes __________.

The enteric nervous system functions __________.

What influence does the cerebral cortex have on the ANS?

Which region of the central nervous system integrates the activities of the autonomic nervous system?
