High Treason in the Holiday Season - S11-E8
Visible crew/equipment: While they're doing a full workup of the room at the Riverbanks Inn, just as Hodgins mentions that Ryan Gill has been in the room like an elephant in a china shop, when Agent Aubrey walks in the T-mark can be seen on the carpet. (In the Netflix version the T-mark has been edited out).
A Night at the Bones Museum - S5-E5
Continuity mistake: The mummy is in direct sunlight with no shadows on him when Cam first walks up to examine him. When Bones and Booth walk up to him, a few seconds later, the right side of his face is in the shadows. (00:04:00)
The Woman in the Garden - S1-E13
Continuity mistake: Booth and Brennan arrive at the crime scene in the beginning of the show. After she has confirmed that the bones in the trunk belonged to a woman, a black car drives by and shots are fired. At first, the trunk of the car is less than halfway opened. Cut to the next shot and the trunk is fully opened. (00:02:10)
The Knight on the Grid - S3-E8
Continuity mistake: Amy comes to see Brennan at night to tell her about her daughter's sickness. There are a bunch of letters on the kitchen counter. The envelopes move around in between shots, most noticeably the brown one. (00:03:20)
The Priest in the Churchyard - S2-E17
Continuity mistake: At the diner, after Dr. Gordon has told Bones and Booth the problem with their relationship, the two shares a triumphant hand slap. Bones' glass refills itself between shots.
Continuity mistake: At the diner, before Mrs. Duncan comes to confess about murdering her husband, Brennan takes a sip of tea. Her glass at this point is less than half full. When Mrs. Duncan walks in, the same glass is now almost full.
Stargazer in a Puddle - S2-E21
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)
The Girl in Suite 2103 - S2-E6
Continuity mistake: When Booth and Brennen are questioning the Senator's son, the cap on the bottle of water keeps switching from being on and being off between shots.
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.
