The superior and middle turbinates are part of the ethmoid bone, whereas the inferior turbinates form a separate and unique bone. Covered by both respiratory and olfactory epithelium, the superior turbinate is located high in the nasal vault and usually arises from the cribriform plate of the ethmoid bone.

What bones form inferior turbinates?

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.

Which bone forms the most inferior turbinates?

Inferior turbinates – are two, small bones that extend into the nasal cavity from the walls of the maxilla bones. Because of their curved shape, the turbinates are also called nasal conchae (L., concha – shell and Gr., konche – mussel or cockle).
