The Witch in the Wardrobe - S5-E20
Continuity mistake: Bones draws a circle around the pentagram; however, it changes designs when we next see it. (00:35:10)
The Witch in the Wardrobe - S5-E20
Continuity mistake: When they reveal that the stab wounds create a pentagram, Brennan misses one of the dots while drawing it, but when they have the pentagram in frame the next time the pentagram has been redrawn. (00:34:57)
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.
