Question 4

What is the balance of ANS stimulation in the heart if heart rate is decreasing?

Answer 4

Parasympathetic stimulation is higher.

Decreased heart rate is a parasympathetic effect.

Question 5

What is the balance of ANS stimulation in the digestive tract if digestive activity is increasing?

Answer 5

Parasympathetic stimulation is higher.

Increased digestive activity is a parasympathetic effect.

Question 6

What is the balance of ANS stimulation in the liver if more glucose is being released?

Answer 6

Sympathetic stimulation is higher.

Glucose release is a sympathetic effect.

Question 7

What is the balance of ANS stimulation in the eye if the pupils are dilating?

Answer 7

Sympathetic stimulation is higher.

Pupil dilation is a sympathetic effect.

Question 8

What is the balance of ANS stimulation in the bladder if a person is having difficulty with urinating (voiding)?

Answer 8

Sympathetic stimulation is higher.

Difficulty urinating indicates sympathetic dominance.

Question 9

How has ANS stimulation changed if a person is producing more sweat?

Answer 9

Sympathetic stimulation has increased.

Sweating is a sympathetic response.

Question 10

What change(s) in ANS stimulation would cause the salivary glands to produce a watery saliva?

Answer 10

Increased parasympathetic stimulation OR decrease in sympathetic stimulation.

Both changes could lead to increased watery saliva.

Question 11

What change(s) in ANS stimulation would cause the bronchioles of the lungs to dilate?

Answer 11

Increased sympathetic stimulation OR decreased parasympathetic stimulation.

Both changes lead to bronchodilation.

Question 12

What change(s) in ANS stimulation of the heart would cause heart rate to decrease?

Answer 12

Increased parasympathetic stimulation OR decrease in sympathetic stimulation.

Both changes result in decreased heart rate.

Question 13

What change(s) in ANS stimulation would cause the activity of the digestive tract to increase?

Answer 13

Increased parasympathetic stimulation OR decrease in sympathetic stimulation.

Both promote digestive activity.

Question 14

What change(s) in ANS stimulation would cause the liver to release more glucose?

Answer 14

Increased sympathetic stimulation.

Sympathetic stimulation increases glucose release.

Question 15

What change(s) in ANS stimulation would cause the pupils of the eye to dilate?

Answer 15

Increased sympathetic stimulation OR decreased parasympathetic stimulation.

Both lead to pupil dilation.

Question 16

What change(s) in ANS stimulation in the bladder would cause difficulty with urinating (voiding)?

Answer 16

Increased sympathetic stimulation.

Sympathetic dominance affects bladder function.

Question 17

What change(s) in ANS stimulation would cause a person to produce more sweat?

Answer 17

Increased sympathetic stimulation.

Increased sweating is a sympathetic response.

Question 18

Which kind of ANS-modifying drug(s) will cause heart rate to increase?

Answer 18

Either an adrenergic receptor agonist or a muscarinic receptor antagonist.

Both can result in increased heart rate.

Question 19

Which kind of ANS-modifying drug(s) would cause the salivary glands to produce a watery saliva?

Answer 19

A muscarinic receptor agonist OR an adrenergic receptor antagonist.

Both can stimulate saliva production.

Question 20

Which kind of ANS-modifying drug(s) would cause the bronchioles of the lungs to dilate?

Answer 20

An adrenergic receptor agonist OR a muscarinic receptor antagonist.

Both can induce bronchodilation.

Question 21

Which kind of ANS-modifying drug(s) would cause heart rate to decrease?

Answer 21

A muscarinic receptor agonist OR an adrenergic receptor antagonist.

Both can lead to decreased heart rate.

Question 22

Which kind of ANS-modifying drug(s) would cause the activity of the digestive tract to increase?

Answer 22

A muscarinic receptor agonist OR an adrenergic receptor antagonist.

Both promote digestive activity.

Question 23

Which kind of ANS-modifying drug(s) would cause the liver to release more glucose?

Answer 23

An adrenergic receptor agonist.

Sympathetic stimulation increases glucose release.

Question 24

Which kind of ANS-modifying drug(s) would cause the pupils of the eye to dilate?

Answer 24

An adrenergic receptor agonist OR a muscarinic receptor antagonist.

Both can induce pupil dilation.

Question 25

Which kind of ANS-modifying drug(s) would cause difficulty with urinating (voiding)?

Answer 25

An adrenergic receptor antagonist. ## Footnote It decreases sympathetic stimulation, aiding urination.

Question 26

Which of the following changes in autonomic stimulation would result in dilation of the bronchioles of the lung?

Answer 26

Either increasing sympathetic stimulation or decreasing parasympathetic stimulation. ## Footnote Both result in bronchodilation.

Question 27

Which of the following modifiers of ANS stimulation would cause dilation of the pupils?

Answer 27

Adrenergic receptor agonist. ## Footnote Dilation of pupils is a sympathetic effect.

Question 28

Which of the following changes would you expect to see in someone taking an adrenergic receptor antagonist?

Answer 28

Lowered amount of glucose release into the blood. ## Footnote Blocking adrenergic receptors reduces sympathetic effects.

Question 29

What kind of adrenergic receptor-modifying drug would be used to treat a tachycardic patient?

Answer 29

Adrenergic receptor antagonist. ## Footnote It helps lower heart rate.

Question 30

Which kind of change in ANS activity would help relieve low gastrointestinal motility?

Answer 30

Either decreasing sympathetic stimulation or increasing parasympathetic stimulation. ## Footnote Both would enhance GI activity.

Question 31

What kind of autonomic-modifying drug is albuterol?

Answer 31

Adrenergic receptor agonist. ## Footnote It dilates bronchioles to alleviate asthma symptoms.

Question 32

Which of the following would be a possible effect of activating beta-3 adrenergic receptors?

Answer 32
