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 Plain in the Prodigy - S5-E3
Continuity mistake: When Sweets comes to look at the rocks he puts his gloves on. Camera changes, and he's putting his second glove on a second time. (00:15:20)
The Plain in the Prodigy - S5-E3
Continuity mistake: The girl says that she saw a "full on Amish guy" who looked pissed. When she says this to Booth, he hand disappears from her chin instantly. (00:24:40)
The Plain in the Prodigy - S5-E3
Continuity mistake: When finding out that the key cover broke Levi's hand, Bones is holding a bone in her hands and examining it. When the shot changes she isn't holding the bone any more. (00:34:30)
The Beautiful Day in the Neighborhood - S5-E4
Continuity mistake: At the start we see Nate having a drink from his cup and then lower the cup. When the shot changes he's drinking from the cup again. (00:01:00)
The Beautiful Day in the Neighborhood - S5-E4

The Beautiful Day in the Neighborhood - S5-E4
Factual error: Near the end, the gang is using Luminol to check for blood on neighbourhood signs. Luminol won't work in broad daylight, they should have used a blue light filtering lens to enhance its visibility.
The Beautiful Day in the Neighborhood - S5-E4
Continuity mistake: Near the end, as Parker drinks his milkshake, its contents rise & fall (not counting his drinking some). Also, he moves the glass about enough to illustrate that it's fake - it would have spilled, the way he handles it.
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)
A Night at the Bones Museum - S5-E5
Factual error: Hodgins makes a remark about the mummy wrappings being for an important person because it is a diamond weave pattern. However, the diamond weave pattern didn't come into effect until the Greco-Roman period that began at 332 B.C. It certainly wouldn't be found in an 18th dynasty mummy, no matter how important he was.
A Night at the Bones Museum - S5-E5
Factual error: Hodgins says that natron was a naturally drying agent, which was used in the second century B.C. This is both wrong and right. While it is true that natron was used for mummification, it was used for thousands of years in Egyptian culture, not just the second century B.C.

The Tough Man in the Tender Chicken - S5-E6
Continuity mistake: As Hodgins says he will chip in for the pig, the item he's holding has 4 items sticking out of it. When the shot changes, these items change position. (00:31:00)
The Tough Man in the Tender Chicken - S5-E6
Continuity mistake: The position of the pig picture Angela places on the item Hodgins is holding changes places. First it's resting on 2 spikes then 3. (00:31:05)

Continuity mistake: The amount of paint on Wendel's hat keep changing drastically. Most noticeable is when Bones stops him spinning and leans him forward. (00:34:15)
Continuity mistake: When Angela tells Gordon about the python, Gordon has the sandwich up to his mouth in one shot and lowered in the next. (00:23:40)
Continuity mistake: When Angela is in the diner with Gordon, she has her drink in her hand. When the shot changes, her glass is on the table. (00:23:40)
Visible crew/equipment: When Booth is being shown around the gold shop a black tape marker is visible by the door where Booth stops. (00:26:00)
Continuity mistake: When Novarro, Booth and Bones are looking at the drain, there are a few marks on the floor by Booth's feet. In the close up these marks have disappeared. (00:27:00)
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.
