choroid plexus in dogs

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 dog.

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 15 typed relationships for it, across 6 kinds of connection. part of brain ventricle, central nervous system and circulatory system, and 2 more.

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 ventricle, central nervous system, circulatory system, organ and tela choroidea.

Is the choroid plexus the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
