-heart rate changes -alterations in respirations -altered blood pressure -problems swallowing
28
The meninges surrounding the brain comprise the: (2)
dura mater pia mater
29
CSF is produced by? location?
ependymal cells of chorioid plexus in 3rd and 4th ventricles
30
where is CSF reabsorbed?
arachnoid villa
31
spinal cord grey matter
process/think
32
spinal cord white matter
sending
33
dorsal nerve root neuron name? (send or recieve?)
affarent (arrives) recieve
34
ventral nerve root neuron name? (send or receive?)
efferent (exit) send
35
sympathetic NS function
rest/digest
36
parasympathetic NS
fight/flight
37
2 divisions of Autonomic NS
sypathetic parasympathetic
38
sympathetic NS neurotransmitters
mild: norepinephrine power: epinephrine
39
parasympathetic NS neurotransmitter
acetylcholine
40
somatic
voluntary control of motor nerves
41
Wallerian degeneration
healing of PNS nerves absorb injurt to NOT cause scarring
42
injury to CNS
doesn't heal well d/t increased scar formation
43
does the PNS or CNS heal better
PSN
44
what cell needs to be alive for degeneration
schwann cell
45
one fucntion of the somatic nervous system that is NOT performed by the autonomic NS is conduction of impulses: (mc)
to skeletal muscle
46
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)
bipolar
47
neruons that carry impulses away from CNS are called? (mc)
efferent nerurons
48
neurons are specialized for the conduction of impuslese, whereas neuroglia: (mc)
support nerve tissue
49
there is one-way conduction at a synapse because: (mc)
only the presynaptic neruon contains neurotransmitters
50
which contains the thalamus and hypothalamus? (mc)
diencephalon
51
the reticular activating systme: | (mc)
maintains wakefullness
52
which phrases best describe the spinal cord (2) (mc)
conducts motor impuses from the brain conducts sensroy impulse to the brain
53
which is not a protective covering of the CNS? (mc)
cuada equine
54
the composition of CSF fluid is | (mc)
a plasma like liquid with glucoe, salts, and proteins
55
an autonomic ganglion can be descries as? (mc)
the side of synapses between visceral efferent neurons
56
the sympathetic division of the autonomic NS: (mc)
is innervated by cell bodies from T1 through L2 and is innervated by cell bodies located in the cranial nerve nuclei
57
the parasympathetic division of the autonomic NS: (mc)
conserves and stores energy and has relatively short postganglionic neurons
58
schwann cells
produces a myelin sheath
59
dendrite
conducts impusles to cell body
60
sensory neuron
carries impulses to the CNS
61
effector
responds to motor impulse
62
cranial nerve for tasting
facial
63
cranial nerve for balance maintenance
vestibulocochlear
64
more extensive use of norepinephrine as a transmitter ? (symp or parasym)
sympathetic
65
more widespread and generalized effects | (symp or parasymp)
sympathetic
66
elicits rest-response
parasympathetic
67
