Chapter 15 : Structure of the Autonomic Nervous System

Question 1

Autonomic Nervous System is not

Answer 1

voluntary

Question 2

ANS manages a many unconscious processes such as

Answer 2

regulates homeostasis

Question 3

Homeostasis can not be maintained without the

Answer 3

ANS

Question 4

ANS

Answer 4

motor nervous system that controls glands, cardiac
muscle, and smooth muscle

Question 5

The AANS is also called

Answer 5

visceral motor system

Question 6

Primary targets organs of ANS are

Answer 6

Viscera (organs) of thoracic and abdominal cavities

Also some structures in the body’s cutaneous membrane
– cutaneous blood vessels (i.e. thermoregulation)
– sweat glands
– piloerector muscles

Question 7

the visceral organs are or are not dependent on the ANS for
their main functions?

Answer 7

are not

Question 8

ANS simply _______ the organs function!

Answer 8

adjusts

Question 9

ANS carries out actions

Answer 9

involuntarily

Question 10

ANS is used to ______ the function of the organ

Answer 10

adjust

Question 11

receptors

Answer 11

nerve endings that detect stretch, tissue damage,
blood chemicals, body temperature, and other internal stimuli

Question 12

afferent neurons

Answer 12

send stimulus to the CNS

Question 13

interneurons

Answer 13

only in the CNS

Question 14

efferent neurons

Answer 14

carry motor signals away from the CNS to
target tissue

Question 15

the effectors

Answer 15

make adjustments in homeostasis by
regulating these tissues /// cardiac, smooth muscle, or a
gland

Question 16

Visceral Reflex In Response to High BP

Answer 16

(1) high blood pressure detected by arterial
stretch receptors
(2) afferent neuron carries signal to CNS & interneurons process signals
(3) efferent neurons carry signals to the heart
(4) heart slows reducing blood pressure

Question 17

Divisions of ANS

Answer 17

Sympathetic and parasympathetic division
