The
human
spine,
however,
differs
from
that
of
other
animals
in
respect
to
its
suitability
for
the
erect
posture.
Man
is
the
only
animal
in
the
world
who
can
straighten
his
body
and
stand
perfectly
erect.
Even
the
anthropoid
apes
when
standing
on
their
feet
assume
a
somewhat
oblique
position.
The
vertebral
column
in
animal
life
was
first
developed
on
the
horizontal
plane,
and
so,
naturally,
when
man
was
evolved
and
adopted
the
erect
position,
certain
modifications
of
the
spine
were
necessary.
A
new
strain
developed
on
the
vertebral
column
which
was
due
to
the
new
position,
and
so
there
came
about
certain
changes
in
its
structure.
For
one
thing
the
spine
became
less
flexible
and
gained
in
stability,
especially
in
the
lower
sections.
The
sacrum,
for
instance,
is
created
by
the
fusing
together
of
several
vertebrae
into
one
bone
for
the
sake
of
greater
strength
and
stability.
The
sacrum
in
man
is
much
broader
than
in
animals,
for
it
must
supply
solidity
and
strength
to
the
lower
part
of
the
spine,
thus
adapting
it
to
the
vertical
position,
and
in
the
same
way
the
lower
vertebrae
generally
are
comparatively
broader
and
heavier,
gradually
decreasing
in
size
and
tapering
toward
the
top
of
the
spine
like
the
trunk
of
a
tree.
This
particular
feature
of
the
human
backbone
is
worthy
of
special
consideration
because
it
is
the
upper
section
of
the
spine,
in
which
the
vertebrae
are
smaller
and
tapering,
that
weakness
is
most
likely
to
exist.
It
is
in
this
upper
section
of
the
spine
that
strength
is
most
needed
in
order
to
preserve
it
in
perfect
alignment,
and
keep
the
body
properly
erect.
And
it
is
for
this
reason,
as
the
reader
will
see,
that
exercises
affecting
the
upper
parts
of
the
spine
are
most
important.
Therefore
I
have
given
them
special
attention.
