Nasal bones

Small, paired bones that form the bridge of the nose.

Nasal bones are two small, elongated bones that make up the upper part of the nasal cavity. They are situated medially in the face and articulate with several surrounding structures, contributing to the shape and support of the nose. Each nasal bone has a rectangular shape and varies in size and thickness among individuals.

Function

The primary function of the nasal bones is to provide structure and support to the nose. They play a crucial role in shaping the nasal bridge, contributing to the overall aesthetic appearance of the face. The nasal bones also protect the underlying nasal structures and help define the nasal passage, ensuring the proper function of breathing and olfaction. Additionally, since the nasal bones help form part of the nasal cavity, they play a role in filtering and humidifying inhaled air before it enters the lungs, enhancing the respiratory process.

Location

Nasal bones are located in the central part of the face, situated side by side at the upper border of the nasal cavity. They form the bridge of the nose and extend from the nasal bridge down to the area where they meet the maxillary bones, which are part of the upper jaw. The nasal bones articulate laterally with the maxillae and superiorly with the frontal bone, allowing for a stable connection to the surrounding facial skeleton. Their position is critical not only for the structural integrity of the nose but also for the facial symmetry and aesthetics.
