We just learned about the part of the inner ear called the Bony Labryinth.
Another part of the inner ear is the Vestibule of the Ear.
The word vestibule means entrance, and this part of the ear has pathways going to the other parts of the inner ear.
It also has some walls that have tiny holes in them where very thin hairlike nerves go through to other parts of the ear.
