Cerebral Veins
No Valves
Lie in the subarachnoid space
Classified into the deep cerebrla veins and the superficial cerebral veins
Deep Cerebral veins
Drain blood from the diencephalon and deep parts of the hemispheres into the great cerebral vein
Great cerebral vein (vena magna cerebri)
○ Basal veins (vena basalis) run underneath the hypothalamus and is formed by a union of small anterior cerebral veins (venae cerebri anteriores)
○ Internal Cerebral Vein (cena interna cerebri)
○ Superior Thalamostriate Vein (vena thalamistriatum superior)
○ Superior Choroid vein
○ Anterior vein of Septum Pellucidum
Superficial Cerebral Veins
Collect blood from the cerebrla cortex and drain into the venous sinuses
Superficial Middle Cerebral Vein (vena cerebri media superficialis)
○ Drains frontal, temporal and parietal lobe.
○ Anestemoting branches: Superior Anastomotic Vein of Troland (v. Anastemotica superior) and Inferior Anastomotic vein of Labbe (vena anastomotica inferior)
Superior Cerebral Veins (vv. Cerebri superiores)
Inferior Cerebral Veins (vv. Cerebri inferiores)
Superior and Inferior Cerebellar Veins (vv. Superiores et inferiores cerebelli)
Diploic Veins
Lie in ''Diploe'' and drains them.
They mainly drain the blood into the venous sinuses
Emissary Veins
Veins that connect the Dural Snuses and the Extracranial Veins
Also called Cranio-Cerebral Anastomosis
Parietal Emissary Vein (vena emissaria parietalis)
Mastoid Emissary Vein (vena emissaria mastoidea)
Occipital Emissary Vein (vena emissaria occipitalis)
Condylar Emissary Vein (vena emissaria condylaris)
Diploic Veins
Emissary Veins
