Flashcards in Set 18 ANS and higher cortical functions Pg 23 Deck (43):
1

What is the general function of the sympathetic NS?

fight or flight

2

What is the general function of the parasympathetic NS?

winde and dine

3

What is the effect of the SNS on blood vessels, skin, and muscles?

vasoconstricts, shunts blood to proximal limbs and lungs

4

What is the effect of the PSNS on blood vessels, skin, and muscles?

little to no effect

5

What is the effect of the SNS on the heart?

increases rate (tachycardia)

6

What is the effect of the PSNS on the heart?

decreases rate (bradychardia)

7

What is the effect of the SNS on the lung and bronchi?

deep breathes and dilates bronchi

8

What is the effect of the PSNS on the lung and bronchi?

shallow breaths and constricts bronchi

9

What is the effect of the SNS on the eyes and pupils?

dilates (medriasis)

10

What is the effect of the PSNS on the eyes and pupils?

constricts (meiosis)

11

What is the effect of the SNS on the GI?

decreases secretions and digestion

12

What is the effect of the PSNS on the GI?

increase secretions and bowel movement

13

What is the effect of the SNS on the receptors?

adrenergic

14

What is the effect of the PSNS on the receptors?

cholinergic

15

What are the SNS neurotransmitters?

Pre: acetylcholine Post: epinepherine and norepinepherine

16

What are the PSNS neurotransmitters?

crude sensation

32

What does the hypothalamus control?

ANS and endocrine, body temp, hunger, thirst, rage and agression, maintains sleep cycle

33

What does the hypothalmus release?

somatostatin

34
