Stargazer in a Puddle - S2-E21
Continuity mistake: Near the end we see Bones show Max that she is wearing her grandmother's ring. In the closeup her fingers are all together but in the long shot her fingers are splayed apart. (00:29:30)

Continuity mistake: Max asks Bones to try the ring on and Bones has her arms by her side. As the shot changes she now has her arms crossed in front of her and on the table. (00:09:45)

Continuity mistake: In the establishing shot of the church where Angela and Hodgins are having their wedding, the walls are all white. When they flee the wedding, the exteriors are red brick. (00:36:00)
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.
