Autonomic Nervous System

Question 1

Most tissues are controlled by what division of the autonomic nervous system?

Answer 1

Both the sympathetic and parasympathetic

Question 2

Term that refers to tissues that are controlled by both divisions of the ANS

Answer 2

Dual innervation

Question 3

3 types of structures that make up ANS

Answer 3

1) Preganglionic Neuron
2) Ganglion
3) postganglionic neuron

Question 4

What are preganglionic neurons

Answer 4

Group of neurons whose axons travel to a specific ganglion

Question 5

What are ganglia?

Answer 5

Group of cell bodies, especially postganglionic cell bodies.

Question 6

What occurs at ganglia?

Answer 6

Preganglionic axons synapse w/ postganglionic dendrites

Question 7

Postganglionic cell bodies are found where?

Answer 7

In ganglia

Question 8

Purpose of postganglion neurons

Answer 8

Axons travel to ANS effectors

Question 9

Parasympathetic division is also known as:

Answer 9

Craniosacral division

Question 10

The preganglionic neuron cell bodies of the parasympathetic division are located:

Answer 10

In cranial nerves 3, 7, 9, and 10

and in the lateral gray horns of the sacral region of spinal cord

Question 11

Characteristics of parasympathetic’s preganglonic neurons

Answer 11

Very long

Myelinated

Question 12

Where do the parasympathetic’s preganglionic neurons synapse?

Answer 12

A ganglion called the terminal ganglion

Question 13

Terminal ganglia location

Answer 13

Located near/ inside of effectors

Question 14

What neurotransmitter do the parasympathetic’s preganglionic neurons release?

Answer 14

acetylcholine

Question 15

parasympathetic’s preganglionic neurons release acetylcholine to:

Answer 15

stimulate postganglionic neurons whose cell bodies are housed within the terminal ganglia

Question 16

Parasympathetic’s postganglionic neurons are located:

Answer 16

In the terminal ganglia

Question 17

Parasympathetic’s postganglionic neurons’ axons are:

Answer 17

short and unmyelinated

Question 18

where do the parasympathetic’s postganglionic neurons end?`

Answer 18

Synapse to the effector

Question 19

What neurotransmitter do the parasympathetic’s postganglionic neurons release?

Answer 19

Acetylcholine
