153. Venous sinuses of the dura mater, cerebral veins.
Traces how the cerebral veins leave the subarachnoid space, pierce the arachnoid and dural layers, and drain into the cranial venous sinuses. It separates the superficial system, covering the superior, inferior and middle cerebral veins and their sinus destinations, from the deep system, which follows the thalamostriate and internal cerebral veins to the great cerebral vein and straight sinus. A note points out the superficial middle cerebral vein's links to both the superior sagittal and transverse sinuses.

Deep system:
VENOUS DRINAGE
Veins of the brain emerges to the sub-arachnoid space, then pierces arachnoid matter and meningeal layer of dura matter to drain into cranial venous sinuses.
Superficial system:
Superior cerebral vein: to superior sagittal sinus.
Inferior cerebral veins: to nearby sinuses (mainly transverse sinus).
Middle cerebral veins:
Superficial: to cavernous sinus.
Deep:joins anterior cerebral vein and striate vein to form basal vein, which joins the great cerebral vein.
Notice the connection between superficial middle vein and both superior sagittal and transverse sinuses.
Deep system:
Thalamo-striate vein joins choroidal vein to form internal cerebral vein.
Both internal cerebral veins (right and left) unite to form great cerebral vein.
Great cerebral vein receives both basal veins (right and left), then joins inferior sagittal sinus to form the straight sinus.
