| 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. Synonym: concha nasalis suprema, fourth turbinated bone, highest concha, highest turbinated bone, Santorini's concha, concha santorini, supraturbinal, supreme concha, supreme turbinated bone, turbinated body.

| 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 anterior | A pointed projection at the anterior extremity of the intermaxillary suture; the tip, as seen on a lateral cephalometric radiograph, is used as a cephalometric landmark. Synonym: spina nasalis anterior. (05 Mar 2000) |
| spina nasalis ossis frontalis | A projection from the centre of the nasal part of the frontal bone, which lies between and articulates with the nasal bones and the perpendicular plate of the ethmoid. Synonym: spina nasalis ossis frontalis. (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) |
| nasalis muscle | <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) |
| incisura nasalis | The notch in the medial border of the maxilla anteriorly which, with its fellow, forms most of the piriform opening of the nasal cavity. Synonym: incisura nasalis. (05 Mar 2000) |
| transverse part of nasalis muscle | <anatomy> See: nasalis muscle. Synonym: pars transversa musculi nasalis. (05 Mar 2000) |
| facies nasalis maxillae | The surface of the maxilla that forms part of the lateral nasal wall with a large defect (maxillary hiatus) posteriorly and the lacrimal sulcus in its midportion. Synonym: facies nasalis maxillae. (05 Mar 2000) |
| facies nasalis ossis palatini | The nasal surface of the perpendicular lamina of the palatine bone that forms part of the lateral wall of the nasal cavity, the nasal surface of the horizontal lamina of the palatine bone that forms part of the floor of the nasal cavity. Synonym: facies nasalis ossis palatini. (05 Mar 2000) |
| arteriae alveolaris inferioris | <anatomy, artery> Branch of inferior alveolar artery to the mylohyoid muscle. Synonym: ramus mylohyoideus arteriae alveolaris inferioris, arteriae alveolaris inferioris. (05 Mar 2000) |
| arteria segmenti anterioris inferioris renis | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti anterioris inferioris renis, artery of anterior {inferior segment of kidney}. (05 Mar 2000) |
