Which of these is not a characteristic of the parasympathetic division?

The parasympathetic nervous system is characterized by

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

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

Parasympathetic ganglia that are located within the walls of the innervated organs are called

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.

Postganglionic sympathetic fibers release norepinephrine and are called cholinergic fibers.

Adrenergic postganglionic neurons release the hormones norepinephrine and epinephrine.

**The adrenal medulla is different from the remainder of the sympathetic division because __________.

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

Sympathetic structures of the abdomen that lie anterior to the vertebral column.

Adrenergic hormones are secreted into the bloodstream in this region of the adrenal gland.

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

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

Another name for a chain ganglion is

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

This organ contains modified sympathetic postganglionic neurons that lack nerve processes.

Vagal stimulation of the heart decreases heart rate, resulting in a drop in blood pressure.

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.
