What forms the bony nasal septum?

1. Nasal Spine

2. Perpendicular Plate

3. Vomer

4. All of the above

The correct answer is: All of the above

The bony nasal septum is formed by multiple structures that contribute to its overall anatomy. The perpendicular plate of the ethmoid bone plays a significant role as it constitutes the superior portion of the septum. The vomer, a thin, plow-shaped bone, forms the inferior part of the septum and acts as a central component. Additionally, the nasal spine, which is found on the frontal bone, contributes to the formation of the nasal septum by providing a point of attachment at the anterior aspect. Together, these structures—perpendicular plate, vomer, and the nasal spine—create a complete bony nasal septum that separates the left and right nasal cavities, allowing for proper airflow and function of the respiratory system. The collective contribution of all these components underscores why the correct answer encompasses all of them.
