The meninges surrounding the brain comprise the: (2)

A

dura mater pia mater

29
Q

CSF is produced by? location?

A

ependymal cells of chorioid plexus

in 3rd and 4th ventricles

30
Q

where is CSF reabsorbed?

A

arachnoid villa

31
Q

spinal cord grey matter

A

process/think

32
Q

spinal cord white matter

A

sending

33
Q

dorsal nerve root

neuron name?

(send or recieve?)

A

affarent (arrives)

recieve

34
Q

ventral nerve root

neuron name?

(send or receive?)

A

efferent (exit)

send

35
Q

sympathetic NS function

A

rest/digest

36
Q

parasympathetic NS

A

fight/flight

37
Q

2 divisions of Autonomic NS

A

sypathetic

parasympathetic

38
Q

sympathetic NS neurotransmitters

A

mild: norepinephrine
power: epinephrine

39
Q

parasympathetic NS neurotransmitter

A

acetylcholine

40
Q

somatic

A

voluntary control of motor nerves

41
Q

Wallerian degeneration

A

healing of PNS

nerves absorb injurt to NOT cause scarring

42
Q

injury to CNS

A

doesn’t heal well d/t increased scar formation

43
Q

does the PNS or CNS heal better

A

PSN

44
Q

what cell needs to be alive for degeneration

A

schwann cell

45
Q

one fucntion of the somatic nervous system that is NOT performed by the autonomic NS is conduction of impulses:

(mc)

A

to skeletal muscle

46
Q

a neuron with a single dendrite at one end of the cell body and single axon at the other end of the cell body would be classified as?

(mc)

A

bipolar

47
Q

neruons that carry impulses away from CNS are called?

(mc)

A

efferent nerurons

48
Q

neurons are specialized for the conduction of impuslese, whereas neuroglia:

(mc)

A

support nerve tissue

49
Q

there is one-way conduction at a synapse because:

(mc)

A

only the presynaptic neruon contains neurotransmitters

50
Q

which contains the thalamus and hypothalamus?

(mc)

A

diencephalon

51
Q

the reticular activating systme:

(mc)

A

maintains wakefullness

52
Q

which phrases best describe the spinal cord (2)

(mc)

A

conducts motor impuses from the brain

conducts sensroy impulse to the brain

53
Q

which is not a protective covering of the CNS?

(mc)

A

cuada equine

54
Q

the composition of CSF fluid is

(mc)

A

a plasma like liquid with glucoe, salts, and proteins

55
Q

an autonomic ganglion can be descries as?

(mc)

A

the side of synapses between visceral efferent neurons

56
Q

the sympathetic division of the autonomic NS:

(mc)

A

is innervated by cell bodies from T1 through L2

and

is innervated by cell bodies located in the cranial nerve nuclei

57
Q

the parasympathetic division of the autonomic NS:

(mc)

A

conserves and stores energy

and

has relatively short postganglionic neurons

58
Q

schwann cells

A

produces a myelin sheath

59
Q

dendrite

A

conducts impusles to cell body

60

sensory neuron

A

carries impulses to the CNS

61

elicits rest-response

A
