2

The first of two motor neurons in any autonomic motor pathway is called

preganglionic neuron

3

Which of the following responses is initiated by the sympathetic nervous system?

splitting glycogen to glucose by the liver

4

Because the principal active ingredient in tobacco is nicotine, you might expect smoking to enhance the effects of

acetylcholine on any postganglionic neurons.

5

Which of the following is stimulated by the parasympathetic nervous system?

erection of the penis

6

Muscarinic receptors are

found on all effectors innervated by the parasympathetic postganglionic axons

7

Alpha and beta receptors are associated with

sympathetic neurons.

8

Autonomic nervous system motor output continues to the spinal cord through relays in the

reticular formation.

9

Acetylcholine is inactivated by the enzyme

esterase

10

Autonomic dysreflexia is characterized by

A) pounding headache.
B) hyptertension.
C) flushed, warm skin with profuse sweating about injury level.
D) anxiety.
