choroid plexus
A network formed by blood vessels and the tela choroidea which secretes CSF into the ventricular spaces. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the choroid plexus is
A network formed by blood vessels and the tela choroidea which secretes CSF into the ventricular spaces. The atlas records it as a region at the region scale in the human body.
Where the choroid plexus is
It sits within the cardiovascular and nervous systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What the choroid plexus connects to
The atlas records 12 typed relationships for it, across 5 kinds of connection. part of brain, brain ventricle and tela choroidea.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the choroid plexus. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.
Also called
Also recorded as CP, chorioid plexus, plexus choroideus, choroid plexus of cerebral hemisphere and ventricular choroid plexus. Searching any of those names reaches this page.

Questions
Where is the choroid plexus?
It sits within the cardiovascular and nervous systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What does the choroid plexus connect to?
Part of: brain, brain ventricle and tela choroidea.
Is the choroid plexus the same in other species?
Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
