posterior semicircular canal in dogs

The posterior semicircular canal is a part of the vestibular system and detects rotations of the head in the sagittal plane. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the posterior semicircular canal is

The posterior semicircular canal is a part of the vestibular system and detects rotations of the head in the sagittal plane. The atlas records it as a organ at the organ scale in the dog.

Where the posterior semicircular canal is

It sits in the head, within the sensory system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the posterior semicircular canal connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. a kind of semicircular canal.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the posterior semicircular canal. 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 canalis semicircularis posterior, caudal vertical semicircular canal, pars superior of labyrinth, posterior semicircular canals and posterior semicircular duct. Searching any of those names reaches this page.
