endolymphatic duct

The small membranous canal, connecting with both saccule and utricle of the membranous labyrinth, passing through the aqueduct of vestibule, and terminating in the endolymphatic sac. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the endolymphatic duct is

The small membranous canal, connecting with both saccule and utricle of the membranous labyrinth, passing through the aqueduct of vestibule, and terminating in the endolymphatic sac. The atlas records it as a organ at the organ scale in the human body.

Where the endolymphatic duct is

It sits in the head, within the sensory system. 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 endolymphatic duct connects to

The atlas records 5 typed relationships for it, across 3 kinds of connection. part of membranous labyrinth.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the endolymphatic duct. 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 ductus endolymphaticus. Searching any of those names reaches this page.

Questions

Where is the endolymphatic duct?

It sits in the head, within the sensory system. 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 endolymphatic duct connect to?

Part of: membranous labyrinth.

Is the endolymphatic duct 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.
