Which bone structure forms the bridge of the nose?

Nasal
Frontal
Maxillary
Zygomatic

The correct answer is: Nasal

The nasal bone structures are specifically responsible for forming the bridge of the nose. Each side of the nasal bridge is made up of two nasal bones that articulate at the midline, creating the prominent structure that is often referred to as the "bridge of the nose." These bones are small and rectangular in shape, situated between the frontal bones and the maxillary bones. The frontal bone contributes to the forehead and the upper part of the eye sockets, but it does not play a direct role in forming the nose's bridge. The maxillary bones, which form the upper jaw and part of the orbits, also do not constitute the bridge itself but rather are positioned below the nasal bones. The zygomatic bones, commonly known as the cheekbones, are located laterally and also do not contribute to the formation of the nasal bridge.
