Endocranium and dural sinuses
Remove
the
calvarium
of
the
skull
and
examine
the
interior
of
the
cranium.
The
base
of
the
endocranium
is
divided
into
three
cranial
fossae:
anterior,
middle
and
posterior.
The
anterior
cranial
fossa
is
separated
from
the
middle
cranial
fossa
by
a
bone
ridge,
the
lesser
wing
of
sphenoid
bone
.
Identify
it
and
follow
it
towards
the
midline,
notice
how
it
ends
in
two
projections,
the
anterior
clinoid
processes
.
The
middle
cranial
fossa
is
separated
from
the
posterior
cranial
fossa
by
an
elongated
pyramid
shape
bone protrusion, the
petrous part of the temporal bone
.

The
anterior
cranial
fossa
contains
the
frontal
lobe,
in
its
medial
part
notice
a
perforated
part
of
the
bone,
the
cribriform
plate
through
which
the
olfactory
nerve
fibres
pass.
Perpendicular
to
the
cribriform
plate,
locate
a
comb
shaped
plate,
the
crista
galli
.
The
middle
cranial
fossa
contains
the
temporal
lobe.
In
its
medial
part,
on
either
side
of
the
sella
turcica
there
is
a
series
of
foramina arranged in the shape of a crescent, the
crescent of foramina
.
