Autonomic Nervous System

Question 1

Sympathetic

Answer 1

During “fight or flight” responses

-usually travels through spinal cord

Question 2

Parasympathetic

Answer 2

More active during “rest and digest” or “feed and breed” situations
-usually travels through vagus or cranial nerves

Question 3

General sympathetic responses (Physical or mental stress) - 9

Answer 3

1. Increased HR
2. Increased ABP
3. Increased bronchodilation
4. Increased blood flow to muscles
5. Increased strength
6. Increased blood glucose (glycolysis)
7. Increased metabolism
8. Reduced blood flow to GI system
9. Pupil dilation

Question 4

General parasympathetic responses (Relaxed) - 5

Answer 4

1. Decreased HR
2. Decreased ABP
3. Increased bronchoconstriction
4. Increased GI activity
5. Pupil constriction

Question 5

Sympathetic Stimulation - Pupil

Answer 5

Dilated

Question 6

Parasympathetic Stimulation - Pupil

Answer 6

Constricted

Question 7

Sympathetic Stimulation - Ciliary muscles

Answer 7

Slight relaxation (far vision)

Question 8

Parasympathetic Stimulation - Ciliary muscles

Answer 8

Constricted (near vision)

Question 9

Sympathetic Stimulation - Glands (nasal, lacrimal, parotid, submandibular, gastric, pancreatic)

Answer 9

Vasoconstriction and slight secretion

Question 10

Parasympathetic Stimulation - Glands (nasal, lacrimal, parotid, submandibular, gastric, pancreatic)

Answer 10

Stimulation of copious secretion (containing many enzymes for enzyme secreting glands)

Question 11

Sympathetic Stimulation - Sweat glands

Answer 11

Copious sweating (cholinergic)

Question 12

Parasympathetic Stimulation - Sweat glands`

Answer 12

Sweating on palms of hand

Question 13

Sympathetic Stimulation - Apocrine glands

Answer 13

Thick, odiferous secretion

Question 14

Parasympathetic Stimulation - Apocrine glands

Answer 14

None

Question 15

Sympathetic Stimulation - Blood vessels

Answer 15

Most often constricted

Question 16

Parasympathetic Stimulation - Blood vessels

Answer 16

Most often little or no effect

Question 17

Sympathetic Stimulation - Muscle

Answer 17

Increased rate

Increased force of contraction

Question 18

Parasympathetic Stimulation - Muscle

Answer 18

Slowed rate

Decreased force of contraction (especially of atria)

Question 19

Sympathetic Stimulation - Coronaries

Answer 19

Dilated (B2); Constricted (a)

Question 20

Parasympathetic Stimulation - Coronaries

Answer 20

Dilated

Question 21

Sympathetic Stimulation - Bronchi

Answer 21

Dilated

Question 22

Parasympathetic Stimulation - Bronchi

Answer 22

Constricted

Question 23

Sympathetic Stimulation - Lumen

Answer 23

Decreased peristalsis and tone

Question 24

Parasympathetic Stimulation - Lumen

Answer 24

Increased peristalsis and tone

Question 25

Sympathetic Stimulation - Sphincter

Answer 25

Increased tone (most times)

Question 26

Parasympathetic Stimulation - Sphincter

Answer 26

Relaxed (most times)

Question 27

Sympathetic preganglionic NT

Answer 27

Acetylcholine

Question 28

Parasympathetic preganglionic NT

Answer 28

Acetylcholine

Question 29

Sympathetic postganglionic NT and receptors

Answer 29

Norepinephrine and adrenergic receptor

Sweat glands and blood vessels are acetylcholine

Question 30

Parasympathetic postganglionic NT and receptors

Answer 30

Acetylcholine and muscarinic receptors
