25
What does the nissl stain selectively stain
nucleic acids
26
What does the nissl stain show
that neurons are organized
27
What do tract tracing techniques specifically show
how specific neurons are connected to one another
28
What uses afferent-sensory
antegrade
29
what used efferent-motor
retrograde
30
Is antegrade going to or coming from
going to
31
is retrograde going to or coming from
coming from
32
What do inputs in electron microscropy tend to go to
denddrite spines
33
What does electron microscopy show that aren't touching
neurons
34
How does electron micrscopy show proof of hte neuron doctorine
2D image of details
35
Where do axons tend to synapse on
dendrite spines
36
What does 2 photon fluorescence microscopy allow you to see
dendrite spines
37
With laser beams why can't you see synapses
less resolution
38
What is a cluster of cell bodies in the CNS
nuclei and grey matter
39
What is a cluster of cell bodies in the PNS
ganglia
40
What is bundles of axons in teh CNS
tracts and white matter
41
what is bundles of axons in the PNS
nerves
42
What is the basic nueron shape
multipolar
43
multipolar
many things come out of cell body
44
unipopular
one things comes of of cell body
45
Is unipolar or multipolar sensory
unipolar
46
What do sensory neurons bring
sensory info towards CNS
47
Are motor neurons multipolar or unipolar
multipolar
48
Where do motor neurons go out towards
muscles
49
Are interneurons uni or multipolar
multipolar
50
internuerons
everything in between sensory and motor neurons
51
What is mylenation in CNS
Oligodendrocytes
52
What is mylenation in PNS
Schwann Cells
53
What is microenvironment in PNS
satellite cells
54
What is microenvironment in CNS
Astrocytes
55
What are the white blood cells of the CNS
microglia
56
What do Oligodendrocytes send out myelin to
any axon within their vacinit
57
What does Oligodendrocytes myelinate
many part of many axons
58
How is Oligodendrocytes a no grow zone
inhibits axon regrowth to prevent tumors
59
In Oligodendrocytes where are hands reaching out to
multiple axons
60
What do Schwann Cells provide
one chunk of myelin to one axon
61
How are Schwann Cells a pro grow zone
facilitates axon regeneration to recover from injuries
62
In Schwann Cells what are fingers wrapped around
one axon
63
What do Satellite Cells Bear hug
synapeses
64
What do Satellite Cells send chemicals to facilitate
axon-dendrite communication
65
What do Astrocytes bear hug
synapses
66
What do Astrocytes send chemicals to facilate
axon dendrite communication
67
How do Astrocytes surround blood vessels
squeeze them to move blood to places that need it more
68
How is Astrocytes a second level of blood barrier
helps prevent bad stuff from entering brains
69
How are microglia searching
ramified state of little arms reaching out
70
How do Microglia sense damage
activated state and arms retract and microglias go mobile
71
What do Microglia digest
damaged tissue and infection
72
How do Microglia go back to searching
little arms are out sensing for information
