The
nervous
system
has
an
important
role
to
perform
in
the
interacion
functon
.
It
controls
our
enteir
body
sending
,
reciving
and
interpreting
information
from
all
parts
of
our
body
.
These
menssages
travel
through
the
body
as
____________________
impulses
.
But
let´s
see
the
sequence
of
this
travel
:
SENSE
ORGANS
They
respond
to
a
stimulus
and
send
____________________
alon
the
sensory
nerves
.
SENSORY
NERVES
They
carry
information
from
the
sense
organs
and
the
____________________
organs
to
the
central
nervous
system
.
CENTRAL
NERVOUS
SYSTEM
It
recives
and
interprets
information
and
produces
____________________
.
It´s
made
up
of
the
spinal
cord
and
the
____________________
.
-
Spinal
cord
:
The
spinal
cord
produces
fast
and
____________________
responses
.
-
Brain
:
the
brain
is
inside
the
cranium
and
it
makes
decisions
and
gives
orders
.
It
has
three
parts
:
the
cerebrum
,
the
brain
stem
and
the
____________________
.
MOTOR
NERVES
The
central
nervous
system
coordinates
the
infomation
received
and
send
impulses
along
the
____________________
nerves
.
These
motor
nerves
carry
signals
from
the
central
nervous
systen
to
the
____________________
in
the
musculoskeletal
system
.
MUSCULOSKELETAL
SYSTEM
It
brings
a
response
.
These
responses
can
be
etheir
____________________
or
involuntary
response
.
-
Involuntary
movement
:
they´re
produced
by
the
spinal
cord
action
.
Our
____________________
are
involuntary
movements
.
Reflexes
are
fast
and
automatic
responses
.
-
voluntary
movements
:
they´re
produced
by
the
brain
activity
.
the
brain
interprets
the
informationfrom
the
sense
organs
and
produces
a
voluntary
response
.
Voluntary
responses
are
____________________
than
involuntary
responses
.
