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:
“You know, if this is Venus, or some other strange planet, we’re liable to run into some high-domed characters with green blood in their veins who’ll blast at us with their atomic death rayguns, and there we’ll be with these—these poor old-fashioned shootin’ irons.”
—Edward L. Bernds (b. 1911)
