The primary function of the vomer is to support the nasal septum, which divides the nasal cavity into two distinct chambers, allowing for efficient airflow and respiratory function. By doing so, the vomer plays a critical role in regulating nasal air passage, ensuring that air is warmed, humidified, and filtered before it reaches the lungs. Additionally, the vomer contributes to the overall structural integrity of the nasal cavity and helps protect the delicate tissues within. The vomer also serves as an attachment point for nasal structures, supporting the tissue that contains the sensory receptors responsible for the sense of smell.
