Which structure is the Anterior nasal spine located in?

• A. Zygomatic arch
• B. Anterior nasal spine
• C. Bony nasal septum
• D. Angle of mandible

Answer: (B)

The main idea is to know where the anterior nasal spine sits in the facial bones. It is a midline bony projection on the maxilla, located at the lower edge of the nasal aperture where the two halves of the upper jaw meet. This landmark helps define the shape of the nasal opening and serves as a reference point in radiographic positioning. It is not part of the zygomatic arch, the nasal septum, or the mandible; those are different structures—the arch belongs to the cheekbone area, the nasal septum separates the nasal cavities, and the angle of the mandible is the corner of the lower jaw. So, the anterior nasal spine is a feature of the maxilla.
