There
are
two
types
of
____________________
to
stimuli
:
1
)
Motor
responses
:
the
response
is
____________________
.
2
)
____________________
responses
:
the
response
is
the
release
of
hormones
.
The
responsive
organs
,
or
____________________
,
control
motor
and
endocrine
responses
.
MOTOR
RESPONSES
IN
VERTEBRATES
Motor
responses
are
controlled
by
organs
in
the
motor
system
,
which
contist
of
____________________
system
(
____________________
support
the
body
and
act
as
levers
during
movement
.
The
skeleton
is
____________________
)
and
MUSCULAR
system
(
____________________
are
contractile
organs
attached
to
the
bones
by
____________________
)
.
MOTOR
RESPONSES
IN
INVERTEBRATES
Many
invertebrates
possess
an
____________________
,
or
hard
outer
shell
,
which
protects
them
.
Insects
need
a
more
flexible
,
articulated
exoskeleton
because
they
make

ENDOCRINE
RESPONSES
Endocrine
responses
are
controlled
by
____________________
in
the
ENDOCRINE
system
.
These
glands
produce

which
:

are

control
and
coordinate
activities
throughout
the
body
.
Both
vertebrates
and
invertebrates
have
____________________
systems
.
The
motor
and
endocrine
systems
need
to
receive
an
instruction
from
the
____________________
system
in
order
to
respond
.
The
endocrine
system
____________________
functions
which
require
maintained

.
These
include
changes
during
the
metamorphosis
of
some
animals
,

and
the
production
of
