Visible crew/equipment: A potential editing oversight can be found as Booth and Brennan are entering the shooting range by watching the space under the rifle of the third shooter. The gas can be seen coming from the spray can to the shooter's right, not the barrel of the rifle. (00:19:05)
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.
