43
Q

this nervous system funcitons continuously and independently

A

autonomic nervous system

44
Q

in the autonomic nervous system there is no blank effort needed

A

conscious

45
Q

the autonomic nervous system controls blank activities

A

visceral

46
Q

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

A

two

47
Q

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

A

one

48
Q

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

A

ganglia, synapse

49
Q

the somatic nervous system has no peripheral blank or blank

A

synapsing, ganglia

50
Q

two neurons of autonomic nerve fibers

A

preganglionic, postganglionic

51
Q

two divisions of the autonomic nervous system

A

sympathetic, parasympathetic

52
Q

division of autonomic nervous system for stressful situations

A

sympathetic

53
Q

division of the ANS that restores body to restful state

A

parasympathetic

54
Q

sympathetic and parasympathetic may blank

A

work together

55
Q

sympathetic and parasympathetic often work blank

A

antagonistically

56
Q

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

A

organs

57
Q

the sympathetic ganglia is made of the blank of blank neurons

A

soma, postganglionic

57
Q

two types of sympathetic ganglia

A

chain, collateral

58
Q

sympathetic chain has blank on each side

A

one

59
Q

fusion causes individual blank in the sympathetic chain

A

variability

60
Q

there are no cervical blank neurons

A

sympathetic

61
Q

there are cervical sympathetic blank

A

ganglia

62
Q

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

A

T1 to L2

63
Q

in chain preganglionic fibers, there is no cervical blank input

A

nerve

64
Q

go to office hours if i don’t get it

A

okay

65
Q

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

A

spinal, white ramus

66
Q

there are blank paths that a chain preganglionic impulse can take

A

three

67
Q

chain postganglionic fibers exit via the blank

A

gray ramus

68
Q

presynaptic fibers go straight through chain ganglion without blank

A

synapsing

69
Q

three major collateral ganglia

A

celiac, superior mesenteric, inferior mesenteric

70
Q

collateral ganglia deal for the most part with blank processes

A

digestive

71
Q

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

A

adrenal medullae

72
