Continuity mistake: Near the end, as Parker drinks his milkshake, its contents rise & fall (not counting his drinking some). Also, he moves the glass about enough to illustrate that it's fake - it would have spilled, the way he handles it.
Answer: Since the palatine bone is a bone that helps form the mouth it has a lot to do with speaking. The shape of it differs a lot depending on your ethnic background. I would guess that they, in the show, meant that the person's bone tells that they were Japanese and that it was "made for the purpose of speaking Japanese." That's what I'd assume anyway. I've studied molecular biology though, so I'm not an expert on bones.
