Autonomic Nervous System

Question 1

Hormones

Answer 1

chemical messengers that are manufactured by the endocrine glands, travel through the bloodstream, and affect other tissues

Question 2

Heart Sympathetic and Parasympathetic Response

Answer 2

-Sympathetic stimulation leads to increased heart rate and increased contractile force

-Parasympathetic stimulation leads to decreased heart rate and decreased contractile force

Question 3

Lung Sympathetic and Parasympathetic Response

Answer 3

-Sympathetic stimulation causes bronchodilation

-Parasympathetic stimulation causes bronchoconstriction

Question 4

Kidneys sympathetic and parasympathetic response

Answer 4

• Sympathetic stimulation leads to decreased output
• Parasympathetic stimulation has no effect on the kidneys

Question 5

Systemic Blood Vessels sympathetic and parasympathetic response (skin, muscle, and abdominal)

Answer 5

Sympathetic: Abdominal constricted Muscle constricted (alpha) and dilated (beta) Skin Constricted

Parasympathetic: None

Question 6

Liver sympathetic and parasympathetic response

Answer 6

Sympathetic stimulation causes glucose release

Parasympathetic stimulation causes slight glycogen synthesis

Question 7

Blood Glucose Sympathetic and Parasympathetic Response

Answer 7

• Sympathetic stimulation leads to increased blood glucose
• Parasympathetic stimulation has no effect on blood glucose levels

Question 8

Sweat Glands Sympathetic and Parasympathetic Response

Answer 8

Sympathetic stimulation leads to copious sweating (increased up to 100%)

Parasympathetic stimulation causes no change in sweat gland activity

Question 9

Pupils Sympathetic and Parasympathetic Response

Answer 9

• Sympathetic stimulation causes dilated pupils
• Parasympathetic stimulation causes constriction

Question 10

Basal Metabolism Sympathetic and Parasympathetic Response

Answer 10

• Sympathetic stimulation leads to increased basal metabolism
• Parasympathetic stimulation has no effect on basal metabolism

Question 11

Skeletal Muscle Sympathetic and Parasympathetic Response

Answer 11

• Sympathetic stimulation leads to increased strength
• Parasympathetic stimulation causes no change in skeletal muscle strength

Question 12

adrenergic receptors

Answer 12

receptor sites for the sympathetic neurotransmitters norepinephrine and epinephrine

Question 13

Sympathomimetic drugs

Answer 13

A class of drugs whose effects mimic those resulting from the stimulation of the sympathetic nervous system.

Question 14

Sympatholytics

Answer 14

drugs that inhibit the postganglionic functioning of the sympathetic nervous system

Question 15

Catecholamines

Answer 15

dopamine, norepinephrine, epinephrine

Question 16

bronchodilator

Answer 16

-A medication that relaxes and expands the bronchial passages into the lungs

-Act more on Beta 2 receptors than on Beta 1 receptors

Question 17

Alpha 1 receptor actions

Answer 17

-Peripheral vasoconstriction -Increased contractile force
-Decreased HR

Question 18

Alpha 2 receptor actions

Answer 18

-Decreased catecholamines in circulation
-Vasodilation and decreased BP

Question 19

Beta 1 Receptors Action

Answer 19

-Increased Heart Rate
-Increased Contractile Force
-Increased Automaticity

Question 20

Beta 2 Receptors Action

Answer 20

Increased: vasoDILATION, bronchoDILATION Decreased: GI activity, Uterine smooth muscle contraction

Question 21

Beta 3 Receptors Action

Answer 21

Lipolysis Thermogenesis

Question 22

Dopaminergic receptors

Answer 22

-An additional adrenergic receptor

-Stimulated by dopamine

-Causes dilation of the following blood vessels, resulting in increased blood flow Renal Mesenteric Coronary Cerebral

Question 23

acetylcholine receptors

Answer 23

nicotinic and muscarinic

Question 24

Acetylcholine Receptor Locations

Answer 24

-Neuromuscular: Nicotinic
-CNS and ANS: Muscarinic and Nicotinic

Question 25

nicotinic muscle receptor

Answer 25

cholinergic receptor located at the neuromuscular junction of skeletal muscle and initiates muscular contractions as part of the SNS

Question 26

Muscirinic receptors

Answer 26

Found in many organs and responsible for promoting the parasympathetic response.
