| bond angle | This refers to the angle formed between two nuclei which are linked together. (09 Oct 1997) |
|---|---|
| brewster's angle | <physics> The angle of incidence at which electromagnetic waves reflected from a dielectric medium are completely polarized perpendicular to the plane of incidence, the component polarized parallel to the plane of incidence is completely transmitted. (09 Oct 1997) |
| Broca's angle | More specifically see: Broca's basilar angle, Broca's facial angle, occipital angle of parietal bone. (05 Mar 2000) |
| Broca's basilar angle | The angle formed at the basion of lines drawn from the nasion and the alveolar point. Synonym: Broca's angles. (05 Mar 2000) |
| Broca's facial angle | The angle formed by the intersection at the biauricular axis of lines drawn from the supraorbital point and the alveolar point. Synonym: Broca's angles. (05 Mar 2000) |
| bucco-occlusal angle | The line of junction of the buccal and occlusal surfaces of a tooth. (05 Mar 2000) |
| cardiodiaphragmatic angle | The angle between the heart and the diaphragm at either lateral end of the cardiac projection on imaging (usually the chest X-ray film). The right cardiophrenic angle is normally indistinguishable from the cardiohepatic angle radiographically. Synonym: cardiodiaphragmatic angle, phrenopericardial angle. (05 Mar 2000) |
| cardiohepatic angle | The angle formed by the upper border of the liver and the right border of the heart, especially as defined by percussion. Synonym: cardiohepatic triangle. (05 Mar 2000) |
| cardiophrenic angle | The angle between the heart and the diaphragm at either lateral end of the cardiac projection on imaging (usually the chest X-ray film). The right cardiophrenic angle is normally indistinguishable from the cardiohepatic angle radiographically. Synonym: cardiodiaphragmatic angle, phrenopericardial angle. (05 Mar 2000) |
| gamma angle | <ophthalmology> The angle formed between a line joining the fixation point to the centre of the eye and the optic axis. (05 Mar 2000) |
| malocclusion, angle class I | Malocclusion in which the mandible and maxilla are anteroposteriorly normal as reflected by the relationship of the first permanent molar (i.e., in neutroclusion), but in which individual teeth are abnormally related to each other. (12 Dec 1998) |
| malocclusion, angle class II | Malocclusion in which the mandible is posterior to the maxilla as reflected by the relationship of the first permanent molar (distoclusion). (12 Dec 1998) |
| malocclusion, angle class III | Malocclusion in which the mandible is anterior to the maxilla as reflected by the first relationship of the first permanent molar (mesioclusion). (12 Dec 1998) |
| Ranke's angle | The angle formed by the horizontal plane of the head and a line passing from the centre of the margin of the alveolar arch of the maxilla, below the nasal spine to the centre of the frontonasal suture. Origin: J. Ranke (05 Mar 2000) |
| venous angle | The junction of the internal jugular and subclavian veins, toward which converge the external and the anterior jugular and the vertebral veins, the thoracic duct in the left angle and the right lymphatic duct in the right angle. Synonym: Pirogoff's angle. In neuroradiology, the angle of union of the superior thalamostriate vein (vena terminalis) with the internal cerebral vein, usually closely behind the interventricular foramen of Monro.
