Synonym: concha nasalis media, middle turbinated bone, turbinated body. (05 Mar 2000) |
| concha nasalis superior | The upper thin, spongy, bony plate with curved margins, part of the ethmoidal labyrinth, projecting from the lateral wall of the nasal cavity and separating the superior meatus from the sphenoethmoidal recess, the above bony plate and its thick mucoperiosteum, which is less vascular than that of the middle and inferior conchae. Synonym: concha nasalis superior, Morgagni's concha, superior turbinated bone, turbinated body. (05 Mar 2000) |
| concha nasalis suprema | A small concha frequently present on the posterosuperior part of the lateral nasal wall; it overlies the supreme nasal meatus.

| musculus nasalis | <anatomy> Compound muscle consisting of: a transverse part (pars transversa musculi nasalis, musculus compressor naris) arising from the maxilla above the root of the canine tooth on each side and forming an aponeurosis across the bridge of the nose; and an alar part (pars alaris musculi nasalis, musculus dilator naris) arising from the maxilla above the lateral incisor and attaching to the wing of the nose; the alar part dilates the nostril; nerve supply, facial. Synonym: musculus nasalis, nasal muscle. (05 Mar 2000) |
| crista nasalis | The midline ridge in the floor of the nasal cavity, formed by the union of the paired maxillae and palatine bones; the vomer attaches to the crest. Synonym: crista nasalis, saemicrista incisiva. (05 Mar 2000) |

| spina nasalis posterior | The sharp posterior extremity of the nasal crest of the hard palate. Synonym: spina nasalis posterior, posterior palatine spine. (05 Mar 2000) |
