cochlea

The spiral-shaped bony canal in the inner ear containing the hair cells that transduce sound. Its core component is the Organ of Corti, the sensory organ of hearing, which is distributed along the partition separating fluid chambers in the coiled tapered tube of the cochlea. [WP,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the cochlea is

The spiral-shaped bony canal in the inner ear containing the hair cells that transduce sound.

Questions

Where is the cochlea?

It sits in the head, within the skeletal and sensory systems. Positioned deliberately as part of this species body plan.

What does the cochlea connect to?

Part of: bony labyrinth.

Is the cochlea 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.
