The neurotransmitters-
excitatory
and

Which system in the ANS is fight or flight?
Sympathetic
Which system in the ANS is rest or digest?
Parasympathetic
What are myotomes?
muscles
innervated by one
motor
nerve eg c1

What is the strip of skin served by one nerve from one dorsal root ganglion?

Why does shingles appear in specific
patches
?

of the
spine
correspond to
specific nerves
for areas of skin.
So the patch of skin the nerve damaged in shingles is the part that will be affected
What are the two types of white matter in the spinal cord?
ascending
axons from
sensory
input
descending
axons for
motor
input
How is a reflex different than a normal sensory reaction?
It only
bypasses
the
spinal cord
and
ignores
going to the
brain
What part of the PNS controls external stimuli?
Somatic
What part of the PNS controls internal signals?
Autonomic
What part of the nervous system controls input computation and output?
cns =
computation
pns =
input
and
output
What is white matter?
the
connections
between other
cells
What is the difference between anatomy and physiology?
a
is a
static screenshot
of the brain
with structures but physiology
is
Why can we use animals to mimic human brains?
Share
the same
brain structures
and
relative spatial positions
What are the 3 different types of MRI's?
Structural-
different size of static structures
functional-
finding areas of brain with activity
Why dont we use pet scans that often?
expensive
and
invasive
What does a pet scan do?
detect radiation
given out by
binding
of
tracer molecules-
get a

of
endogenous proteins
to
find
their
activity
How does glucose differ in pet scans of those with/without alzheimers?
-F-FDG
shows
metabolically active
areas as it is taken up like

Give an example case study for the neuropsychology method
HM- global amnesia- damage

specific section
What is a coronal slice of the brain?
A
coronal
slice of the brain is a

view of the brain from
