Conchae is the plural of concha, which is an anatomical term for any external structure that resembles a shell in shape
Meatuses is the plural of meatus, which is an anatomical term for a natural opening or channel
The passageways are called the inferior meatus, the middle meatus and the superior meatus.
The five structures in the internal nose are the nasal septum, superior, middle, and inferior nasal conchae, and the nasal meatuses. These structures help humidify and filter the air we breathe before it reaches the lungs.
The superior and middle conchae are processes of the ethmoid bone whereas the inferior concha is an independent paired bone.
The Superior and medial nasal conchae is located in the Ethmoid Bone. So I believe the answer would be Ethmoid.
The fleshy lobes in the nasal cavity that increase surface area are called nasal conchae or turbinates. They help to humidify, warm, and filter the air that passes through the nasal cavity before it reaches the lungs.
Conchae are shelflike structures found in the nasal cavity. They are three pairs of bony projections—superior, middle, and inferior conchae—that help to increase the surface area within the nasal passages. This structure aids in filtering, warming, and humidifying the air we breathe, as well as enhancing our sense of smell. The conchae also play a role in directing airflow and influencing nasal airflow patterns.
The superior and medial nasal conchae is part of the ethmoid bone of the cranium. Ethmoid bone separates nasal cavity from the brain.
The conchae form the upper chambers of the nasal cavities. They increase the surface area of these cavities. That allows for rapid warming and humidification of air before it passes into the lungs
Meatus is the Latin plural. Apparently, meatus or meatuses can be correct in English. "...the plural of meatus remains meatus in Latin or becomes meatuses in English..." Per http://www.dartmouth.edu/~humananatomy/resources/etymology.htm And also some references such as Dorland's state that the plural is also meatus. This appears to be one of those things that is changing over as doctors use it (correctly or incorrectly). Docs say meatuses per my personal experience.
The plural of meatus is meatuses or meatus - both forms are accepted.
the ethmoid bone
The bony projections are called the superior, middle and inferior conchae. They increase surface area to warm and moisten incoming air.
