What is the function of the ethmoid bone?

The ethmoid bone plays a significant role in the structure of the nasal cavity. It contributes to the formation of the upper nasal septum, the lateral nasal walls, and the roof of the nasal cavity. The lightweight, spongy nature of the ethmoid bone allows it to house numerous air cells, which help to humidify and filter the air we breathe. Additionally, its position between the eyes is crucial for the function of the turbinates, which further facilitate the passage of air into the respiratory system. The ethmoid's intricate structure also supports the sense of smell by housing the olfactory bulbs, making it essential not only for the anatomy of the nasal cavity but also for respiratory function and olfaction.
