Flashcards in Ch 16 and 17 Lec 1 - Nerve Tracts and the ANS Deck (75):
1

two types of sensory/motor pathways

ascending, descending

2

sensory/motor pathway that conducts sensory impulses

ascending

3

sensory/motor pathway that conducts motor impulses

descending

4

sensory and motor pathways blank in complexity

vary

5

three sensory pathways

first order neuron, second order, third order

6

sensory patthway that sends info to CNS

first order neuron

7

sensory pathway that receives impulses from first; spinal cord or brain stem

second order

8

sensory pathway that carries signal from thalamus to cerebral cortex

third order

9

how many somatic motor mathways

2

10

how many autonomic motor pathways

three

11

somatic motor pathway that is in the CNS

upper motor neuron

12

somatic motor pathway that is from the CNS to effector

lower motor neurons

13

autonomic motor pathway that is in CNS

upper motor neuron

14

autonomic motor pathway that is from CNS to peripheral ganglion

preganglionic neuron

15

autonomic motor pathway that is from ganglion to effector

postganglionic neuron

16

ascending pathway where the sides cross in medulla

posterior column pathway

17

posterior column pathway is for sensory impulses from blank, muscles, tendons, and blank

skin, joints

18

posterior column pathway perceives things like fine blank, pressure, and body blank

touch, positino

19

ascending pathway where sides cross in the spinal cord

spinothalamic pathway

20

two tracts of the spinothalamic pathway

lateral, anterior

21

tract of the spinothalamic pathway that is for sensation of pain and temperature

lateral

22

spinothalamic pathway tract that is for sensation of crude touch and pressure

anterior tract

23

ascending pathways go from blank nerves to blank

spinal, cerebral cortex

24

ascending pathway that is for proprioception for fine coordination

spinocerebellar

25

two tracts of the spinocerebellar pathway

anterior, posterior

26

tract of spinocerebellar pathway where sides cross in spinal cord

anterior

27

tract of spinocerebellar pathway that does not cross over

posterior tract

28

in the spinocerebellar pathway there is no synapse in the blank

thalamus

29

the spinocerebellar pathway never makes it to the blank and is for blank processing

cortex, subconscious

30

descending pathway that has the corticobubular tract, lateral corticospinal tract, and anterior corticospinal tract

corticospinal

31

tract of corticospinal pathway that has motor cranial nerves

corticobubular tract

32

tract of corticospinal pathway that has motor spinal nerves and crosses over in medulla

lateral corticospinal tract

33

corticospinal pathway tract that has motor spinal nerves and does not cross over

anterior corticospinal tracts

34

descending pathway that stimulate and inhibit same lower motor neurons as corticospinal

medial pathway

35

descending pathway that is for muscle tone and precise movements of distal upper limb

lateral pathway

36

lateral pathway stimulates and inhibits same lower motor neurons as blank

corticospinal

37

tract of the lateral pathway that starts in the red nucleus and crosses over

rubrospinal tracts

38

rubrospinal tracts extend to blank region of the spinal cord

cervical

39

three descending pathways

medial, lateral, corticospinal

40

three tracts of medial pathway

tectospinal, reticulospinal, vestibulospinal

41

three tracts of corticospinal pathway

corticobulbar, anterior corticospinal, lateral corticospinal

42

lateral pathway tract

rubrospinal

43

this nervous system funcitons continuously and independently

autonomic nervous system

44

in the autonomic nervous system there is no blank effort needed

conscious

45

the autonomic nervous system controls blank activities

visceral

46

the autonomic nervous system has pathways with usually blank neuron(s)

two

47

the somatic nervous system usually has blank peripheral motor axon(s)

one

48

autonomic nervous system may result in additional blank and results in an additional blank

ganglia, synapse

49

the somatic nervous system has no peripheral blank or blank

synapsing, ganglia

50

two neurons of autonomic nerve fibers

preganglionic, postganglionic

51

two divisions of the autonomic nervous system

sympathetic, parasympathetic

52

division of autonomic nervous system for stressful situations

sympathetic

53

division of the ANS that restores body to restful state

parasympathetic

54

sympathetic and parasympathetic may blank

work together

55

sympathetic and parasympathetic often work blank

antagonistically

56

certain blank may only be innervated by one of the sympathetic or parasympathetic divisions

organs

57

the sympathetic ganglia is made of the blank of blank neurons

soma, postganglionic

57

two types of sympathetic ganglia

chain, collateral

58

sympathetic chain has blank on each side

one

59

fusion causes individual blank in the sympathetic chain

variability

60

there are no cervical blank neurons

sympathetic

61

there are cervical sympathetic blank

ganglia

62

the chain ganglion is innervated by presynaptic fibers from nerves blank to blank

T1 to L2

63

in chain preganglionic fibers, there is no cervical blank input

nerve

64

go to office hours if i don't get it

okay

65

preganglionic fibers leave the blank nerve and enter the chain via the blank

spinal, white ramus

66

there are blank paths that a chain preganglionic impulse can take

three

67

chain postganglionic fibers exit via the blank

gray ramus

68

presynaptic fibers go straight through chain ganglion without blank

synapsing

69

three major collateral ganglia

celiac, superior mesenteric, inferior mesenteric

70

collateral ganglia deal for the most part with blank processes

digestive

71

presynaptic fibers go through both the chain and collateral ganglia in this

adrenal medullae

72

adrenal medullae stimulate the production of the hormones blank and blank

epinephrine, norepinephrine

73

there are no blank fibers in the adrenal medullae

postganglionic

74

epinephrine and norepinephrine make up blank

adrenaline
