| bony saemicircular canals | The three bony tubes in the labyrinth of the ear within which the membranous saemicircular ducts are located; they lie in planes at right angles to each other and are known as anterior saemicircular canal, posterior saemicircular canal, and lateral saemicircular canal. Synonym: canales saemicirculares ossei. (05 Mar 2000) |
|---|---|
| crura of bony saemicircular canals | The extremities of the bony saemicircular canals in which the corresponding membranous limbs of the saemicircular ducts are located; they are the common bony crus, simple bony crus, and ampullary bony crus. Synonym: crura ossea canalium saemicircularium, limbs of bony saemicircular canals. (05 Mar 2000) |
| limbs of bony saemicircular canals | The extremities of the bony saemicircular canals in which the corresponding membranous limbs of the saemicircular ducts are located; they are the common bony crus, simple bony crus, and ampullary bony crus. Synonym: crura ossea canalium saemicircularium, limbs of bony saemicircular canals. (05 Mar 2000) |
| limbus of bony spiral lamina | The border of the spiral lamina; the thickened periosteum covering the upper plate of the bony spiral lamina of the cochlea. Synonym: limbus laminae spiralis osseae. (05 Mar 2000) |
| accessory nasal cartilages | Variable small plates of cartilage located in the interval between the greater alar and lateral nasal cartilages. Synonym: cartilagines nasales accessoriae, sesamoid cartilages of nose. (05 Mar 2000) |
| anterior nasal aperture | The anterior nasal opening in the skull. Synonym: apertura piriformis, piriform opening. (05 Mar 2000) |
| anterior nasal spine | 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) |
| benign nasal tumour | A benign tumour of the posterior nasopharynx that is most common in adolescent boys. Symptoms repeated epistaxis, nasal congestion, nasal discharge and hearing loss. A skull X-ray or a CT scan of the head can confirm the presence of an angiofibroma. Treatment may include the surgical removal of the lesion if it is enlarging or blocking the airway. (27 Sep 1997) |
| medial nasal branches of anterior ethmoidal nerve | <anatomy, nerve> Branches of nasociliary nerve distributed to the nasal septum. Synonym: rami nasales mediales nervi ethmoidalis anterioris. (05 Mar 2000) |
| medial nasal fold | An ectodermally covered mesenchymal swelling lying medial to the olfactory placode or pit in the embryo. Synonym: medial nasal fold, medial nasal primordium, medial nasal process. (05 Mar 2000) |
| medial nasal primordium | An ectodermally covered mesenchymal swelling lying medial to the olfactory placode or pit in the embryo. Synonym: medial nasal fold, medial nasal primordium, medial nasal process. (05 Mar 2000) |
| medial nasal process | An ectodermally covered mesenchymal swelling lying medial to the olfactory placode or pit in the embryo. Synonym: medial nasal fold, medial nasal primordium, medial nasal process. (05 Mar 2000) |
| medial nasal prominence | An ectodermally covered mesenchymal swelling lying medial to the olfactory placode or pit in the embryo. Synonym: medial nasal fold, medial nasal primordium, medial nasal process. (05 Mar 2000) |

| middle nasal concha | The middle 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 middle meatus, the above bony plate and its thick mucoperiosteum containing a cavernous vascular bed for heat exchange. Synonym: concha nasalis media, middle turbinated bone, turbinated body. (05 Mar 2000) |
