Inferior Nasal Concha. The Inferior nasal concha is the most caudally based of the three nasal conchae. While the superior and middle nasal conchae form part of the perpendicular plate of the ethmoid bone, the inferior nasal concha is a bony structure by itself.It sits on the vertical bony plate known as the nasal septum, separating the nasal cavity into two bilateral and symmetrical anatomical caves.nferior Nasal Concha. The Inferior nasal concha is the most caudally based of the three nasal conchae. While the superior and middle nasal conchae form part of the perpendicular plate of the ethmoid bone, the inferior nasal concha is a bony structure by itself.
The medial wall of the nasal cavity is formed by both bony elements and cartilage. Posteriorly the perpendicular plate of the ethmoid bone forms the superior septum and the vomer forms the inferior part of the septum.Further posteriorly the crest of both the maxilla and palatine bone complete the posterior septum.he most medial end of the cartilage causes the elevation of the mucous membrane. The Hard Palate is a horizontal plate of bone formed by both the palatine process of the maxilla and the horizontal plate of the palatine bone.
