The internal cerebral veins (deep cerebral veins) drain the deep parts of the hemisphere and are two in number; each internal

cerebral vein In human anatomy, the cerebral veins are blood vessels which drain blood from the cerebrum of the human brain. They are divisible into ''external'' ( superficial cerebral veins) and ''internal'' (internal cerebral veins) groups according to the ...

superior choroid vein The choroid veins are the superior choroid vein, and the inferior choroid vein of the lateral ventricle. Both veins drain different parts of the choroid plexus. Superior choroid vein The superior choroid vein runs along the length of the choroid ...
