The internal cerebral veins (deep cerebral veins) drain the deep parts of the hemisphere and are two in number; each internal
cerebral vein is formed near the
interventricular foramina by the union of the
superior thalamostriate vein and the
superior choroid vein.
They run backward parallel with one another, between the layers of the
tela chorioidea
The tela choroidea (or tela chorioidea) is a region of meningeal pia mater that adheres to the underlying ependyma, and gives rise to the choroid plexus in each of the brain’s four ventricles. ''Tela'' is Latin for ''woven'' and is used to desc ...

third ventricle
The third ventricle is one of the four connected ventricles of the ventricular system within the mammalian brain. It is a slit-like cavity formed in the diencephalon between the two thalami, in the midline between the right and left lateral v ...

splenium
The corpus callosum (Latin for "tough body"), also callosal commissure, is a wide, thick nerve tract, consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. The corpus callosum is only found in placental m ...

The great cerebral vein is one of the large blood vessels in the skull draining the cerebrum of the brain. It is also known as the "vein of Galen", named for its discoverer, the Greek physician Galen. However, it is not the only vein with this epon ...

basal vein
The basal vein is a vein in the brain. It is formed at the anterior perforated substance by the union of
* (a) a ''small anterior cerebral vein'' which accompanies the anterior cerebral artery and supplies the medial surface of the frontal lobe b ...
