Exam 15: The Autonomic Nervous System and Visceral Sensory Neurons

Autonomic fibers to the pelvic organs pass through the pelvic plexus, also known as the plexus.

The parasympathetic nervous system is characterized by

The plexus is a network through which branches of the vagus pass to the intestines and liver.

The primary integrating center of the ANS is the of the diencephalon.

A nurse encountered a patient in a wheelchair 3 months after the patient had sustained a crushing injury to his cervical spinal cord at the level of C6 in a motorcycle accident. Although the patient was paralyzed, his limbs were thrashing, his face was bright red, and he was sweating profusely. What was happening?

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

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

All of the following have only sympathetic innervation except the

Which of these is not innervated by the ANS?

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

Division of the ANS most active during vigorous exercise describes the

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

What stimulates the adrenal medulla to secrete its excitatory neurohormones?

Only about half a dozen parasympathetic ganglia have specific names. Two of these are the

Parasympathetic impulses to the stomach pass through the

Sacral nerves carrying parasympathetic innervation to the pelvic organs.

Location in the brain of the cardiorespiratory and vasomotor control centers.

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

The sympathetic system causes

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