If you think about that a moment and think about both how much they can move and how complexly they can move and their ability to elongate and to change shape, they do it in a way that's completely different from the kinds of movements we're used to.
So when we move an arm or a leg, it's very understandable.
We have bones and muscles.
Muscles move the bones.
The bones are hinged at joints.
And so we have a simple lever system that is familiar to most people who are using levers every day, whether they're conscious of it or not.
The point being that for most movement, muscles and bones interact to create movement.
In the case of tongues, there are no bones, no joints, no levers.
The tongue is pure muscle, and yet it's able to elongate, change shape, exert force, do finely controlled manipulations.
And it's doing that all on its own.
Organs that do these kinds of movements using only muscle, they're called muscular hydrostats.
But we can simplify that and just think of them as something like a water balloon.
So imagine yourself holding a balloon that's kind of a long, narrow balloon, and you filled it with water.
And it's important to recognize that balloon, it's elastic and stretchy, right?
And it's filled with fluid.
But water, you can't squeeze water and compress it, right?
Like it doesn't matter how hard you push on it.
It's not going to get any denser or smaller or compact.
It's going to stay exactly the same.
The water in your water balloon, no matter how much you squeeze on that water balloon, the volume isn't going to change.
