Unformatted text preview: 1)After
a
brain
surgery
gone
wrong,
you
notice
you
have
great
difficulty
using
the
distal
parts
of
 your
limbs
independently
of
other
body
movements.
You
are
still
able
to
use
axial
and
proximal
 muscles
to
stand,
walk,
and
run.
After
a
few
weeks,
you
begin
using
your
fingers,
but
the
ability
 to
make
independent,
fractionated
movements
of
the
fingers
never
returns.
The
damage
to
the
 direct
projections
from
the
motor
cortex
to
the
spinal
cord
happened
at
what
level?
 
 a.
midbrain.
 b.
pons
 c.
motor
cortex
 d.
medulla
 
 answer:
d
these
observations
show
that
following
damage
to
the
direct
projects
from
the
motor
 cortex
to
the
spinal
cord
at
the
level
of
the
medulla,
the
inderect
projections
from
the
motor
 cortex
via
the
brain
stem
centers
are
capable
of
sustaining
motor
behavior
that
involves
 primarily
the
use
of
proximal
muscles.
 
 2)
the
telencephalon
in
the
embryonic
brain
later
gives
rise
to
what
adult
brain
derivatives?
 
 a.
dorsal
thalamus,
hypothalamus,
superior
and
inferior
colliculi
 b.
basal
ganglia,
hippocampus,
olfactory
bulb,
and
basal
foramen
 c.
cerebellum,
pons,
medulla,
and
spinal
cord
