The Skull in the Desert - S1-E17
Continuity mistake: During the scene when Booth and Bones are driving to tell Angela that her boyfriend is dead, the scenery behind Booth jumps suddenly mid shot. Initially the scene is of a wide plain, then suddenly a mountain range appears. This scene was obviously shot on a sound stage, with the scenic background being projected onto screens around the vehicle, an old trick in movie making. It seems that somebody mistimed the loop of the tape they were using. (00:12:30)
The Graft in the Girl - S1-E20
Continuity mistake: When Angela asks to see the girl's drawing, in the shot from the girl's perspective as she hands the pad over, the painting's quite small in the centre of the page. When it then cuts to Angela's point of view it takes up nearly the whole page. (00:02:45)
The Graft in the Girl - S1-E20
Continuity mistake: When Bones goes to open the vent on the wall in the mortuary while standing on the coffin, the shot from inside the grate shows her taking a step up and being exactly at head height for it. Only problem is that in the shot previous to this she was significantly short of the grate, and there was nothing on the coffin lid for her to step up onto.

Booth has been trying to find victims from out of state, but says nothing when these come up on the screen. Shortly after this is shown, Hodgins tells him about a victim in Lynchberg, Virginia. He then takes action as the victim is from out of state. He should've noticed the others. (00:20:10)

Brennan has her arms folded across her chest, when the shot changes and you see her in the mirror her arms are hanging down at her sides, then when it changes back her arms are folded again. (00:15:00)

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.
