| mesial angle | The angle formed by the meeting of the mesial with the labial (or buccal) or lingual surface of a tooth. (05 Mar 2000) |
|---|---|
| right angle clamp | A clamp with a short 90 |
| metafacial angle | The angle between the pterygoid processes and the base of the skull. Synonym: Serres' angle. (05 Mar 2000) |
| meter angle | The amount of convergence required to view binocularly an object 1 meter distant and exerting 1 diopter of accommodation. Synonym: unit of ocular convergence. (05 Mar 2000) |
| Rolando's angle | The angle which the fissure of Rolando (central sulcus) makes with the midplane. (05 Mar 2000) |
| phase angle | <microscopy> The angular equivalent of the time displacement between corresponding points on two sine waves of the same frequency. (05 Aug 1998) |
| phrenopericardial 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) |
| closed-angle glaucoma | angle-closure glaucoma |
| Pirogoff's 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. (05 Mar 2000) |
| Weisbach's angle | A craniometric angle formed by the junction, at the alveolar point, of lines passing from the basion and from the middle of the frontonasal suture. (05 Mar 2000) |
| Welcker's angle | The anterior inferior angle of the parietal bone. Synonym: angulus sphenoidalis ossis parietalis, sphenoid angle, sphenoidal angle, Welcker's angle. (05 Mar 2000) |
| pitch angle | <physics> For a charged particle moving in a magnetic field, this is the angle arctan (v-perp/v-parallel), where v-parallel is the component of the particle's velocity parallel to the magnetic field, and v-perp is the perpendicular component. The pitch angle is zero when the particle moves purely parallel to the field, and 90-degrees when the particle has no parallel velocity at all. (09 Oct 1997) |
| pitch angle scattering | <physics> Scattering (collisional, or due to wave-particle effects) of particles in velocity space, in which the pitch angle (see entry above) is changed. (09 Oct 1997) |
| contra-angle | 1. One of the double or triple angles in the shank of an instrument by means of which the cutting edge or point is brought into the axis of the handle. 2. An extension piece added to the end of a dental handpiece which, through a set of bevel gears, changes the angle of the axis of rotation of the bur in relation to the axis of the handpiece. (05 Mar 2000) |
| point angle | The junction of three surfaces of the crown of a tooth, or of the walls of a cavity. (05 Mar 2000) |
