Which nasal concha is a separate bone

The inferior nasal conchae are considered a pair of facial bones since they articulate with their respective maxillae bones and project horizontally into the nasal cavity.

Superior to the inferior nasal conchae are the middle nasal conchae and superior nasal conchae. Unlike the inferior conchae, these are not separate bones, but medial extensions of the labyrinth portion of the ethmoid bone.

The medial surface is convex, perforated by numerous apertures, and traversed by longitudinal grooves for the lodgement of vessels. The lateral surface is concave and forms part of the inferior meatus. Its upper border is thin, irregular, and connected to various bones along the lateral wall of the nasal cavity. The inferior border is free, thick, and cellular in structure, especially in the middle of the bone. The inferior nasal concha is ossified from a single center, which appears about the fifth month of fetal life in the lateral wall of the cartilaginous nasal capsule.
