**Core Concept**
Pneumatic bones are air-filled bones that contain one or more air-filled cavities. These bones are primarily found in the skull and are characterized by their light weight and unique structure, which allows for the presence of air-filled spaces. The presence of pneumatic bones is a characteristic feature of the human skull.

**Why the Correct Answer is Right**
The correct answer is not specified, but typically, pneumatic bones include the maxilla, zygoma, lacrimal bone, palatine bone, inferior nasal conchae, and turbinate bones. These bones contain air-filled cavities, such as sinuses, which play a crucial role in the regulation of skull pressure, resonance of sound, and possibly even the reduction of skull weight. The presence of air-filled spaces also enables the skull to maintain its shape and provide a framework for the attachment of muscles and other facial structures.

**Clinical Pearl / High-Yield Fact**
Pneumatic bones can be a useful landmark for surgeons and radiologists when performing procedures involving the skull. The presence of air-filled cavities can be visualized on radiographs and can help to identify the location of underlying structures.
