perilymph

Transudate contained in the osseous labyrinth outside the membranous labyrinth.[FMA]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the perilymph is

Transudate contained in the osseous labyrinth outside the membranous labyrinth.[FMA]. The atlas records it as a tissue at the tissue scale in the human body.

Where the perilymph is

It sits in the head, within the skeletal and sensory 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 perilymph connects to

The atlas records 6 typed relationships for it, across 5 kinds of connection. part of cochlea.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the perilymph. 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 liquor cotunnii and perilympha. Searching any of those names reaches this page.

Questions

Where is the perilymph?

It sits in the head, within the skeletal and sensory 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 perilymph connect to?

Part of: cochlea.

Is the perilymph 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.
