Brain Meninges
 
3 layer system of membranes which envelops
the central nervous system.
 
Layers are:
Dura mater
Arachnoid mater
Pia mater
 
Cisterns
 
Cisterns are openings in the subarachnoid
space of the brain created by a separation of
the arachnoid and pia mater. These spaces are
filled with CSF.
 
Brain Cisterns
 
There are many cisterns in the brain, but the notable ones
include:
 
Cisterna magna (cerebellomedullary).
Cisterna pontis (pontine cistern).
Interpeduncular cistern.
Quadrigeminal cistern (superior cistern).
Ambient cistern.
Cistern of the velum interpositum.
Suprasellar/Chiasmatic cistern.
Cistern of lamina terminalis.
Supracallosal  cistern.
Sylvian cistern.

It contains the basilar artery and its pontine
and labyrinthine branches.

Interpeduncular Cistern
 
Lies between the cerebral peduncles.
Continuous below with the pontine cistern,
laterally with the ambient cisterns, and
superiorly with the suprasellar cistern.
It contains the posterior part of the arterial
circle of Willis.
 
Interpeduncular Cistern

Quadrigeminal Cistern
 
lies posterior to qudrigeminal plate of the
midbrain and between the splenium above
and the vermis below.
It is continuous with the interpeduncular
cistern anteriorly through the ambient
cisterns.
Contains the great cerebral vein of Galen.

sheet like cistern that extend around both
sides of midbrain between the
interpeduncular cistern anteriorly and the

vein lie in the anterior part of each ambient
cistern.

Suprasellar / Chiasmatic Cisterns
 
Suprasellar cistern lies above the pituitary
fossa and is continuous posteriorly with the
interpeduncular cistern and laterally with the
sylvian cistern.
It contains the anterior part of the circle of
Willis and the optic nerve as it passes to the
chiasm.
Chiasmatic cistern is the part of suprasellar
cistern that is anterior to the optic nerve.

The cistern of lamina terminalis is the superior
extension of  suprasellar and chiasmatic
cisterns that extend to the superior surface of
corpus callosum as the pericallosal
(supracallosal) cistern.
Pericallosal cistern is continuous posteriorly
with the quadrigeminal cistern.
It contains branches of the anterior cerebral
artery.
