Which bone forms the lower jaw in humans?
The mandible, commonly known as the lower jaw, is the largest and strongest facial bone. It holds the lower teeth in place and is essential for chewing and speaking. The mandible is unique because it is the only movable bone of the skull, allowing for the opening and closing of the mouth. This bone plays a crucial role in the mechanics of mastication, enabling the grinding and breaking down of food. Its development and function are also vital to facial symmetry and aesthetics, contributing to individual facial characteristics.

I knew the answer without seeing the answer choices. My mom had TMJ.

Just read a terrific book called the mandibles by Lionel Shriver. Worth a read .

klmilles,
You are correct. I loved that store too. They shut their doors in 2011. I used to buy props for photography there; mostly butterflies for editorial work. It was truly fascinating to browse the store.

My favorite store in New York City was "Maxilla and Mandible," near the American Museum of Natural History. Now it is only available online, I think. Pity, it was fascinating browsing.

The mandible is the only bone in the skull that can move. When it moves, it moves up. And yet, every time, the Dentist says, "bite down!"
