The choroid veins are the superior choroid vein, and the inferior choroid vein of the

lateral ventricle The lateral ventricles are the two largest ventricular system, ventricles of the brain and contain cerebrospinal fluid (CSF). Each cerebral hemisphere contains a lateral ventricle, known as the left or right ventricle, respectively. Each lateral ...

choroid plexus The choroid plexus, or plica choroidea, is a plexus of cells that arises from the tela choroidea in each of the ventricles of the brain. Regions of the choroid plexus produce and secrete most of the cerebrospinal fluid (CSF) of the central nerv ...

Superior choroid vein

The superior choroid vein runs along the length of the choroid plexus in the lateral ventricle. It drains the choroid plexus, and also the

hippocampus The hippocampus (via Latin from Greek , 'seahorse') is a major component of the brain of humans and other vertebrates. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus is part of the limbic system, a ...

corpus callosum 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 mam ...

. It unites with the

superior thalamostriate vein The superior thalamostriate vein or terminal vein commences in the groove between the corpus striatum and thalamus, receives numerous veins from both of these parts, and unites behind the crus of the fornix with the superior choroid vein to for ...

to form the

internal cerebral vein 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 su ...

Inferior choroid vein

The inferior choroid vein drains the inferior choroid plexus into the

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 by ...
