该 inferior nasal concha is a combined bone in a type of a flat bent plate arranged in the sidelong mass of the nasal hole. The substandard nasal concha isolates the center nasal meatus from the lower nasal meatus. Every inferior nasal concha has two surfaces (平均, sidelong), two fringes (prevalent, second-rate), and two limits (面前, 背部).
The average surface of the inferior nasal concha is raised, punctured, and longitudinally notched by veins. The parallel surface of the substandard nasal concha is inward and partakes in shaping the sub-par nasal meatus.
The prevalent fringe of the inferior nasal concha is thin and sporadic, and it can be isolated from three districts: a foremost area that expresses with the conchal peak of the maxilla, a back locale that explains with the conchal peak of the palatine bone, and a center locale with three procedures – lacrimal, ethmoidal, maxillary – , which are variable fit as a fiddle, and lucid with the lacrimal, ethmoid bone, and maxilla, individually.
The second rate fringe of the inferior nasal concha is free, thick and spongiose. Both the foremost and back furthest points of the inferior nasal concha are limited finishes of the bone, the back being smaller than the front.
Inferior Nasal Concha Anatomy
It broadens on a level plane along the parallel mass of the nasal cavity and comprises of a lamina of springy bone, twisted upon itself like a parchment. The second rate nasal conchae are viewed as a couple of facial bones since they verbalize with their particular maxillae bones and undertaking on a level plane into the nasal depression.
Better than the inferior nasal conchae are the inferior center nasal conchae and predominant nasal conchae. Not at all like the second rate conchae, these are not separate bones, but rather average expansions of the maze segment of the ethmoid bone.
Inferior Nasal Concha Surfaces
The average surface is raised, punctured by various openings, and crossed by longitudinal furrows for the lodgement of vessels. The horizontal surface is curved and frames some portion of the second rate meatus.
Inferior Nasal Concha Borders
Its upper edge is thin, sporadic, and associated with different bones along the parallel mass of the nasal hole. The second rate fringe is free, 厚, and cell structure, particularly amidst the bone.
The upper edge might be isolated into three parts:
- The foremost explains with the conchal peak of the maxilla
- The back with the conchal peak of the palatine bone
The center segment presents three very much stamped forms, which shift much in their size and frame
