Exam 16: Autonomic Nervous System

Mrs.Fearful has surgery in the morning.At her preoperative checkup,her blood pressure and glucose level are elevated.What might be the cause of this temporary increase?

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

Preganglionic neurons conduct impulses from the brain or spinal cord to an autonomic ganglion.

All of the following are characteristics of sympathetic preganglionic neurons except:

What is the name of the enzyme that terminates the action of acetylcholine?

Visceral effectors are innervated by sympathetic fibers.

Norepinephrine is liberated at:

If you were to damage some of the preganglionic fibers that enter the celiac ganglion,what effect would this have on sympathetic stimulation?

A new theory of autonomic neurotransmission says that most postganglionic fibers release two substances to transmit an impulse.

Some parasympathetic postganglionic neurons have their cell bodies in nuclei in the brainstem.

The somatic and autonomic nervous systems are similar in that they both have two efferent neurons between the central nervous system and the effector organ.

An effect of sympathetic stimulation on the eye is constriction of the pupil.

All cell bodies of the autonomic nervous system are located within the CNS.

Under normal,nonstressful conditions,the parasympathetic division is dominant.

Explain the ways in which sympathetic postganglionic neurons travel to their effector organs.Compare the relative length between sympathetic pre- and postganglionic neurons.

Match each term with its description or definition. -neurotransmitter released by adrenergic fibers

Parasympathetic stimulation has no effect on sweat glands.

Parasympathetic stimulation has no effect on any of the following areas except:

All cranial nerves except nerves I and II contain parasympathetic fibers.

Which of the following would not be a major effector of the autonomic nervous system?
