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:
“I am willing, for a money consideration, to test this physical strength, this nervous force, and muscular power with which I’ve been gifted, to show that they will bear a certain strain. If I break down, if my brain gives way under want of sleep, my heart ceases to respond to the calls made on my circulatory system, or the surcharged veins of my extremities burst—if, in short, I fall helpless, or it may be, dead on the track, then I lose my money.”
—Ada Anderson (1860–?)
