How are ants jaws different than human jaws?

They are like human jaws in that they are used for biting.

They differ in practically every other way. Ants (like other typical insects) have four jaws each (two mandibles, two maxillae); the jaws are not made of bone inside and flesh outside, but flesh inside and the hard part (a sort of concrete of sclerotin and chitin) outside.

Ant jaws don't have separate teeth, but have serrations (saw-like pointy bits).

Their jaws work from side to side instead of up and down.

Their jaws are smaller in absolute terms because ants are smaller than humans, but usually larger in relative terms (a human with jaws like a bulldog ant would look like a crocodile).

It is not easy to think of ways in which they are alike.
