Study Guide: Autonomic Nervous System

Somatic motor and autonomic pathways share all of the following except:

Within the sympathetic chain ganglion, the preganglionic fiber may:

Beta receptors bind with:

Which of the following is not an example of sympathetic stimulation?

"Fight or flight" physiologic changes include all of the following except:

The enteric nervous system is a specialized part of the ANS that controls visceral effectors in the gut wall.

Many autonomic effectors are dually innervated.

They sympathetic division is also called the thoracolumbar division.

They sympathetic division is the dominant controller of the body at rest.

Sympathetic responses are usually widespread, involving many organ systems at once.

Each efferent autonomic pathways is made up of [blank_start]autonomic[blank_end] [blank_start]nerves[blank_end], [blank_start]ganglia[blank_end], and [blank_start]plexuses[blank_end].

[blank_start]Preganglionic[blank_end] neurons conduct impulses from the brain stem or spinal cord to an autonomic ganglion.

Sympathetic ganglia located a short distance from the spinal cord are known as [blank_start]collateral[blank_end] ganglia.

Some postganglionic axons return to a spinal nerve by way of a short branch called the gray [blank_start]ramus[blank_end].

Axon terminals of autonomic neurons release either acetylcholine or [blank_start]norepinephrine[blank_end].

In the sympathetic division, preganglionic neurons are relatively [blank_start]short[blank_end] and postganglionic neurons are relatively [blank_start]long[blank_end].

Norepinephrine affects visceral effectors by first binding to [blank_start]adrenergic[blank_end] receptors in their plasma membranes.

The effect of a neurotransmitter on any postsynaptic cell is determined by the [blank_start]characteristics of the receptor[blank_end].

A [blank_start]nicotinic[blank_end] receptor is a main type of cholinergic receptor.

The action of acetylcholine is [blank_start]quickly[blank_end] terminated when hydrolyzed by the enzyme acetylcholinesterase

Both sympathetic and parasympathetic divisions are tonically active, meaning they continually conduct impulses to autonomic effectors.

Sympathetic impulses inhibit effectors and parasympathetic impulses stimulate effectors.

Autonomic centers function in a hierarchy in their control of the ANS, with the highest ranking being the autonomic centers in the cerebral cortex.

The sympathetic system plays a crucial role in maintaining blood pressure.

They sympathetic system dominates during "rest and repair".

Dendrites and cell bodies of sympathetic preganglionic neurons are located in the:
