crista ampullaris

The crista ampullaris is the sensory organ of rotation located in the semicircular canal of the inner ear. The function of the crista ampullaris is to sense angular acceleration and deceleration. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the crista ampullaris is

The crista ampullaris is the sensory organ of rotation located in the semicircular canal of the inner ear. The function of the crista ampullaris is to sense angular acceleration and deceleration. The atlas records it as a sense organ at the organ scale in the human body.

Where the crista ampullaris 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 crista ampullaris connects to

The atlas records 7 typed relationships for it, across 4 kinds of connection. part of semicircular canal, semicircular duct and sensory system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the crista ampullaris. 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 ampullary crest of semicircular duct, ampullary crest and cristae ampullares. Searching any of those names reaches this page.

Questions

Where is the crista ampullaris?

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 crista ampullaris connect to?

Part of: semicircular canal, semicircular duct and sensory system.

Is the crista ampullaris 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.
