Exam 16: Autonomic Nervous System

All postganglionic sympathetic fibers release the neurotransmitter norepinephrine.

Once inside the sympathetic chain ganglion,the preganglionic fiber may:

The parasympathetic nervous system is also called the craniosacral division.

Some modified postganglionic sympathetic fibers act as endocrine glands.

What two enzymes terminate the activity of norepinephrine? How do they compare with the enzymes that terminate the activity of acetylcholine? What effect does this difference have on the body?

Which generalization concerning the autonomic nervous system is not true?

Explain the way parasympathetic neurons travel from the central nervous system to their effector organs.Compare the relative length between the parasympathetic pre- and postganglionic neurons.

List four ways the body adapts itself for maximum energy expenditure during stress conditions.

The postganglionic neurons of both the sympathetic and parasympathetic nervous systems produce acetylcholine as their neurotransmitter.

Monoamine oxidase is an enzyme that enhances the action of norepinephrine.

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

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

If a nerve impulse is being sent to a gland,it will pass through two neurons.

Explain in general,what the function of the sympathetic nervous system is.

Explain the principal of autonomic antagonism and why it is important in maintaining homeostasis.

About half of the parasympathetic fibers travel in the vagus nerve.

A short postganglionic neuron is a characteristic of the sympathetic nervous system.

Explain the source and possible synapse points for the sympathetic preganglionic neurons.

Beta receptors:

Parasympathetic neuron cell bodies are located in:
