And we're looking in just at the part of the cochlea which is the cochlear duct.
There's fluid.
All this area that you see these dots in, there's fluid.
And the, the business end of it is these, are these hair cells.
These blue and red cells.
These are hair cells.
And they, in the cochlea, they look like this.
In the vestibular system, they look like that.
We'll talk about the vestibular system next, in the next unit.
But in the cochlea, there's these three rows of hairs.
They're not actually hair, they're actually cilia,
but they're called hair cells historically.
And what you can see a little bit maybe in this is
that each hair cell is linked to next hair cell.
So, that as they move, there's actually a pulling.
And I, you can see this a little bit better in this slide.
Okay, so, you see, here's one cilia and here's another cilia.
Do you see this right there?
There's a link right there.
This is going from one tip to the next, to the cilia in back of it.
There's another one right there.
These are called tip links.
