The superior and middle conchae are processes of the ethmoid bone whereas the inferior concha is an independent paired bone.
They are in the nasal cavity. They are curved boney projections coveres in mucous secreting epithelium. There are three conchae superior middle and inferior, the middle projects from above the inferior and the superior from above that. The alternative name often used is the turbinates.
Parts of four different bones make up the bony septum: the perpendicular plate of the ethmoid bone, vomer, and the nasal crest of the maxilla and palatine bones. The most common symptom of a deviated septum is nasal congestion, with one side of the nose being more congested than the other, along with difficulty breathing.
the back part of the medial surface of the labyrinth of ethmoid is subdivided by a narrow oblique fissure, the superior meatus of the nose, bounded above by a thin, curved plate, the superior nasal conchae.The bone found in superior nasal concha is part of the ethmoid bone.See also
The superior and medial nasal conchae is part of the ethmoid bone of the cranium. Ethmoid bone separates nasal cavity from the brain.
