"medullary veins: they are numerous and originate 1-2 cm below cortical gray matter and pass through deep medullary white matter and drain into subependymal veins. The medullary veins are arranged in a wedge-shaped manner and distributed at a right angle to subependymal veins."
"subependymal veins: they receive medullary veins and aggregate into greater tributaries, mainly into septal veins, thalamostriate veins, internal cerebral veins, basal vein of Rosenthal and vein of Galen."

"The superficial venous system is comprised of the sagittal sinuses and cortical veins. The cortical veins course along the cortical sulci, drain the cortex and some of the adjacent white matter. There are numerous cortical veins, and most of them are unnamed; however, the large cortical veins can be identified according to their locations. The cortical venous system can be subdivided into superior, middle and inferior groups. Important veins of the superficial cerebral venous system are:"
