vestibular aqueduct in dogs

At the hinder part of the medial wall of the vestibule is the orifice of the vestibular aqueduct, which extends to the posterior surface of the petrous portion of the temporal bone. It transmits a small vein, and contains a tubular prolongation of the membranous labyrinth, the ductus endolymphaticus, which ends in a cul-de-sac between the layers of the dura mater within the cranial cavity.

What the vestibular aqueduct is

At the hinder part of the medial wall of the vestibule is the orifice of the vestibular aqueduct, which extends to the posterior surface of the petrous portion of the temporal bone. It transmits a small vein, and contains a tubular prolongation of the membranous labyrinth, the ductus endolymphaticus, which ends in a cul-de-sac between the layers of the dura mater within the cranial cavity. [WP,unvetted]. The atlas records it as a bone at the organ scale in the dog.

Where the vestibular aqueduct 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 vestibular aqueduct connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. part of osseus labyrinth vestibule and skull.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the vestibular aqueduct. 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 aqueductus vestibuli. Searching any of those names reaches this page.

Is the vestibular aqueduct 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.
