They run backward parallel with one another, between the layers of the tela chorioidea of the third ventricle, and beneath the splenium of the corpus callosum, where they unite to form a short trunk, the great cerebral vein; just before their union each receives the corresponding basal vein. internal cerebral vein Wikipedia:Internal_cerebral_veins UBERON:0035152 FMA:51003 UMLS:C0149579 NCIT:C32838 SCTID:244397006
