The cerebral veins are divisible into external and internal (internal cerebral veins) groups according to the outer surfaces or the inner parts of the hemispheres they drain into.
The external veins are the superior cerebral veins, inferior cerebral veins, and middle cerebral vein.
Famous quotes containing the word veins:
“How shall a man escape from his ancestors, or draw off from his veins the black drop which he drew from his father’s or mother’s life?”
