cochlear modiolus

The central cone shaped core of spongy bone about which turns the spiral canal. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the cochlear modiolus is

The central cone shaped core of spongy bone about which turns the spiral canal. The atlas records it as a bone at the organ scale in the human body.

Where the cochlear modiolus 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 cochlear modiolus connects to

The atlas records 9 typed relationships for it, across 5 kinds of connection. part of bony labyrinth and cochlea.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the cochlear modiolus. 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 modiolus, cochlea modiolus, modiolus cochleae, modiolus of cochlea and columella cochleae. Searching any of those names reaches this page.

Questions

Where is the cochlear modiolus?

What does the cochlear modiolus connect to?

Part of: bony labyrinth and cochlea.

Is the cochlear modiolus 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.
