Superior Sagittal sinus ‑ courses in upper fixed border of falx cerebri; begins anteriorly at foramen cecum and ends posteriorly by becoming continuous with transverse sinus; communicates laterally with outpocketings called venous lacunae; receives blood from Superior Cerebral veins which course on surface of hemispheres (via branches called bridging veins).
Falx cerebelli ‑ small sickle‑shaped fold that projects anteriorly from posterior wall of posterior cranial fossa between cerebellar hemispheres.
Straight sinus ‑ courses between dural layers at junction of falx cerebriĀ  and tentorium cerebelli; posteriorly can join with Superior Sagittal sinus at Confluens of Sinuses or just turn left and be continuous with Transverse sinus.

Falx cerebelli ‑ small sickle‑shaped fold that projects anteriorly from posterior wall of posterior cranial fossa between cerebellar hemispheres.
Transverse sinuses ‑ course posteriorly in fixed part of tentorium cerebelli; arise either at Confluens of Sinuses or as continuations of Superior Sagittal and Straight Sinuses.

 Vein of Galen Aneurysms
Venous drainage from the medial deep nuclei and from the medial occipital and temporal lobes and the superior cerebellar surface occurs through the galenic system.
Since the size and number of perpendicular crossings of primitive arteries and veins are greatest near the relatively massive embryonic choroid plexuses, niduses of most angiomas are thus deeply situated.
Usually, the angioma is situated in the medial posterior hemispheres, the superior cerebellum, the brain stem, or the deep ganglionic structures.

Cavernous sinuses ‑ situated in the middle cranial fossa on each side of the body of the sphenoid bone (both Cavernous sinuses are connected by Intercavernous sinus); receive venous blood from Superior and Inferior Ophthalmic veins, cerebral veins; drains to Superior and Inferior Petrosal sinuses (Snell Fig.
Falx cerebelli ‑ small sickle‑shaped fold that projects anteriorly from posterior wall of posterior cranial fossa between cerebellar hemispheres.
Tentorium cerebelli ‑ crescent-shaped fold, forms roof over posterior cranial fossa; anteriorly has gap called tentorial notch for passage of brainstem.

 CPMC Neurosurgery - Trigeminal Neuralgia (Tic Douloureux)
This may be due to branches of the superior cerebellar artery, basilar artery, or local veins compressing the trigeminal nerve root.
The trigeminal nerve is also known as cranial nerve V. It transmits sensation from the face, eyes and teeth and controls the muscles of mastication (chewing).
In younger patients, trigeminal neuralgia can be caused by tumors in the region of cranial nerve V or (more commonly) by multiple sclerosis.
