internal ear

Complex labyrinthine structure that comprises sensory endorgans specialized for vestibular, auditory, and acoustico-vestibular sensation. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the internal ear is

Complex labyrinthine structure that comprises sensory endorgans specialized for vestibular, auditory, and acoustico-vestibular sensation. The atlas records it as an anatomical structure at the organ scale in the human body.

Where the internal ear is

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

What the internal ear connects to

The atlas records 21 typed relationships for it, across 5 kinds of connection. part of ear.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the internal ear. 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.
