Forms the inferior portion of the nasal septum?

Explanation:
The nasal septum’s lower portion is formed by the vomer. This midline bone sits behind the nasal cartilage and constitutes the inferior half of the septum, articulating with the perpendicular plate of the ethmoid above and with the palatine processes of the maxilla to complete the bony divider between the two nasal chambers. The anterior part of the septum is cartilage, and the superior part comes from the ethmoid bone, so the vomer uniquely provides the inferior bony contribution. The maxilla and nasal bones are involved in the walls and bridge of the nose, not the lower septum.
