| Frankfort-mandibular incisor angle | Any of several variously named and variously defined anatomical angle's that have been used to quantify facial protrusion, in dentistry, the angle formed by the intersection of the orbitomeatal (Frankfort) plane with the nasion-pogonion line (inner lower angle), which establishes the anteroposterior relation of the mandible to the upper face at the orbitomeatal plane. Synonym: Frankfort-mandibular incisor angle. (05 Mar 2000) |

| anterior 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) |
| 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.
