The Twisted Bones in the Melted Truck - S6-E8
Continuity mistake: At the end, when Kathy is saying she would be out in a year tops as she's from a broken home, she has a clump of hair flowing freely in the middle of her forehead. When the shot changes, this hair is now tidy and not flowing in the wind. (00:39:00)
The Twisted Bones in the Melted Truck - S6-E8
Continuity mistake: When Bones and Booth are talking about Hannah meeting Parker, there is a building to Bones' left (screen right); however, during one of the cuts, the buildings on that side have turned into a street. (00:18:10)
Trivia: At around 5 mins 11 seconds into the episode, Vincent Nigel-Murrey and Dr. Saroyan are discussing the bones on the forensic platform. In the background of a shot of Vincent, the x-ray on the screen is of Homer Simpson's head in the middle of the screen, instead of a real human skull.
Continuity mistake: At the funeral, Bones places a rose on top of several other roses on the coffin of the murder victim. When the victim's parents approach the coffin to place their rose on it, most of the roses have vanished. (00:39:05)
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 Beautiful Day in the Neighborhood - S5-E4
Visible crew/equipment: We can see crew reflected in Hodgins' car door as he arrives at the crime scene. (00:20:20)
Continuity mistake: Booth shoots the kidnapper through a door, creating a hole. This hole vanishes when Brennan walks out the door with Megan.
Soccer Mom in the Mini-Van - S3-E2
Continuity mistake: In the opening scene the victim's right hand is by the car shifter when the bomb explodes, but when Booth and Brennan first get to the van, the right hand is melted onto the steering wheel. (00:00:50 - 00:01:35)
Continuity mistake: When Zac is taking photos of the bones, the shot is flipped. Note the logo and writings on his jacket. (00:07:10)
The Cinderella in the Cardboard - S4-E20
Continuity mistake: When Daisy convinces Sweets that she's not cheating on him, her arms move back and forth from his shoulders to around his neck. (00:37:05)
The Science in the Physicist - S4-E19
Continuity mistake: When Bones and Booth get trapped in the resonance chamber, the position of Booth's hands over his ears changes back and forth between shots. (00:34:30)
The Proof in the Pudding - S5-E12
Continuity mistake: At the end when Booth is hugging Brennan after the bone sinks, Brennan's hands go from being clenched to being open to being clenched again. (00:37:00)
The Knight on the Grid - S3-E8
Continuity mistake: When Booth & Bones' taxi gets blown up & flips, the car lands upright, with nothing on the roof except the (now broken) taxi light. Yet when Booth squirms out the driver's side window, there are a few large chunks of asphalt sitting on the roof. (00:25:20)
The Blonde in the Game - S2-E4
Continuity mistake: When Booth and Bones are discussing Helen Majors, Booth gets a phone call and he holds the phone to his left ear with his right hand. In the following shot, he is holding the phone in his left hand. (00:21:05)
The Plain in the Prodigy - S5-E3
Factual error: When Bones and Booth go to visit Levi's parents and Sarah's brother yells at her that she is needed at home, when he gets into the buggy you see him wearing a wedding ring. Amish wear a beard to indicate marital status, not jewelry it is against the religion to wear any decoration including wedding rings. (00:08:50)
The Science in the Physicist - S4-E19
Continuity mistake: When Bones and Booth are looking at the meteorite for the 1st time, they are approached by Chris who folds his arms to talk to the pair. When the shot changes, his hands are now in his pockets. (00:07:50)
The Man with the Bone - S1-E18
Visible crew/equipment: As Agent Booth and Bones are driving to the crime scene after stopping in the parking lot of the Assateague Island National Seashore, you can see the film crew in the reflection of Booth's SUV. (00:04:10)
The Man in the Fallout Shelter - S1-E9
Continuity mistake: During their first night locked in the lab, Bones and Angela are discussing that they should plan a party for Christmas. Bones' bra straps move on her left shoulder between overhead shots and closeup 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.
