| 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) |
| costal angle | The rather abrupt change in curvature of the body of a rib posteriorly, such that the neck and head of the rib are directed upward. Synonym: angulus costae. (05 Mar 2000) |
| costophrenic angle | Costophrenic sulcus as seen on chest radiograph. (05 Mar 2000) |
| pontine angle | <anatomy, oncology> The angle between the cerebellum and the pons, a common site for the growth of acoustic neuromas. (16 Dec 1997) |
| pontine angle tumour | A tumour in the angle formed by the cerebellum and the lateral pons, often refers to an acoustic schwannoma. (05 Mar 2000) |
| craniofacial angle | The angle formed by the basifacial and basicranial axes at the midpoint of the sphenoethmoidal suture. (05 Mar 2000) |
| critical angle | The angle of incidence at which a ray of light, in passing between two media, changes from refraction to total reflection. Synonym: limiting angle. (05 Mar 2000) |
