Flashcards in Ch 16 and 17 Lec 2 - Nerve Tracts and the ANS Deck (46):
1

two effects of sympathetic division

increases alertness, energy, euphoria, increased muscle tone

2

the central nervous system stimulates blank neurons

preganglionic

3

preganglionic neurons always release blank

ach

4

preganglionic neurons are known as blank synapse

cholinergic

5

preganglionic neurons stimulate blank neurons

postganglionic

6

postganglionic neurons release blank

adrenaline

7

adrenergic receptor that responds to both epinephrine and norepinephrine

alpha

8

adrenergic receptor alpha targest blank muscle

smooth

9

adrenergic receptor that only responds to epinephrine

beta

10

cholinergic receptors respond to blank

ach

11

in sympathetic nervous system, preganglionic fibers are blank and postganglionic fibers are blank

short, long

12

synapsing occurs in sympathetic chain or blank ganglia

collateral

13

preganglionic fiber releases blank

ach

14

postganglionic fibers release blank

norepinephrine

15

sympathetic division prepares body for blank

emergencies

16

sympathetic division effects are blank and persistent

widespread

17

division that originates from neurons in midbrain, pons, medulla, and sacral region of the spinal cord

parasympathetic

18

parasympathetic division exit the CNS via blank nerves and blank nerves

cranial, sacral

19

preganglionic fibers of the parasympathetic system go to the blank and blank glands

eyes, facial

20

preganglionic fibers of the parasympathetic system also includes cranial nerve blank

X - vagus

21

postganglionic fibers are blank and are close to or within target blank

short, organs

22

postganglionic fiber effects are much more blank

localized

23

two functions of parasympathetic division

constrict pupils, sexual arousal, stimulate defecation, secrete hormones

24

all neurons release blank in parasympathetic activation

ach

25

parasympathetic activation has blank effects

short lived

26

most organs receive blank from both divisions

innervation

27

sympathetic reaches the cranial area via blank

chain ganglia

28

parasympathetic reaches the cranial area via blank

cranial ganglia

29

sympathetic and parasympathetic mingle at blank such as these two examples

plexuses, cardiac plexus, esophageal plexus

30

simple functional units of the ANS and provide an autonomic motor response

visceral reflex

31

visceral reflexes are common for blank

digestive system

32

two types of visceral reflexes

long, short

33

type of visceral reflex that goes to the CNS for processing

long reflexes

34

visceral reflex that are processed in the autonomic ganglion

short reflexes

35

many control centers in the blank for control of autonomic activity

medulla

36

blank regulates body temperature in the ANS

hypothalamus

37

when a person is stressed, blank system and blank cortex control the ANS

limbic, cerebral

38

neurons in the spinal cord of the sympathetic division

T1-L2

39

on the sympathetic side there are blank ganglion, blank ganglion, and blank

chain, collateral, medulla

40

there are blank paths for a preganglionic fiber of sympathetic division

four

41

postganglionic fibers are blank in the sympathetic division

long

42

parasympathetic division is between these nerves

cervicles and sacrals

43

postganglionic fiber is blank in parasympathetic division

short

44

preganglionic fibers are blank in the parasympathetic division

long

45

sympathetic division postganglionic fibers are blank

adrenergic

46

the preganglionic fibers in both sympathetic and parasympathetic release blank
