biomedicalephemera:

The inner ear and labyrinth, in situ and isolated. Innervation and vasculature displayed in situ.

Arterial and venous circulation of the tympanum (eardrum).

You can see how the inner ear sits within the temporal bone in these illustrations, and can get more of an idea how it fits into the skull. The vestibulocochlear nerve is shown clearly as the white chord-like structure entering from the bottom of the center illustration. This nerve carries signals to the brain regarding both hearing and balance.
