Describe the bony features of the nasal cavity. The nasal cavity is mostly formed by the union of the maxillae. The ethmoid bone is at the rood of the nasal cavity. The perpendicular plate of the ethmoid and the vomer make the bony septum dividing the nasal activity into right and left sides. On the lateral walls of the maxillae are the inferior nasal conchae.
