| substernal angle | The angle between the lower borders of the costal cartilages of the two sides as they approach the sternum. Synonym: angulus infrasternalis, substernal angle. (05 Mar 2000) |
|---|---|
| Daubenton's angle | An angle formed by the junction, at the opisthion, of lines coming from the basion and from the projection in the median plane of the lower border of the orbits. See: Daubenton's line, Daubenton's plane. Synonym: angulus occipitalis ossis parietalis, occipital angle of parietal bone. (05 Mar 2000) |
| sylvian angle | The angle formed by the sylvian line and a line perpendicular to the horizontal plane tangential to the highest point of the hemisphere. (05 Mar 2000) |
| disparity angle | The difference in position of images on the retina, still permitting fusion. (05 Mar 2000) |
| duodenojejunal angle | An abrupt bend in the small intestine at the junction of the duodenum and jejunum. Synonym: flexura duodenojejunalis, duodenojejunal angle. (05 Mar 2000) |
| impedance angle | A term expressing the ratio of electric resistance to electric capacitance (ohms to microfarads) in the tissues of the body or any other substance. (05 Mar 2000) |
| incident angle | <optics> The angle that a ray entering a refracting medium makes with a line drawn perpendicular to the surface of this medium, the angle that a ray striking a reflecting surface makes with a line perpendicular to this surface. Synonym: incident angle. (05 Mar 2000) |
| incisal guide angle | The angle formed with the horizontal plane by drawing a line in the sagittal plane between incisal edges of the maxillary and mandibular central incisors when the teeth are in centric occlusion. (05 Mar 2000) |
| Q angle | <anatomy> The angle formed by lines representing the resultant pull of the quadriceps muscle and the axis of the patellar tendon. (05 Mar 2000) |
| Quatrefages' angle | An angle formed by the meeting of the prolongation of two lines tangential to the most prominent part of the zygomatic arch and to the parietofrontal suture on each side; when the lines remain parallel the angle is zero; when they diverge it is negative. Synonym: Quatrefages' angle. (05 Mar 2000) |
| infrasternal angle | The angle between the lower borders of the costal cartilages of the two sides as they approach the sternum. Synonym: angulus infrasternalis, substernal angle. (05 Mar 2000) |
| iridocorneal angle | The acute angle between the iris and the cornea at the periphery of the anterior chamber of the eye. Synonym: angulus iridocornealis, angle of iris, angulus iridis, filtration angle. (05 Mar 2000) |
| occipital angle of parietal bone | The posterior superior angle of the parietal bone. Synonym: Broca's angles. Synonym: Daubenton's angle. (05 Mar 2000) |
| olfactory angle | The angle formed by the plane of the lamina cribrosa and the basicranial axis. (05 Mar 2000) |
| open-angle glaucoma | <ophthalmology> A disorder which is characterised by increased pressure within the eyeball. This occurs secondary to the chronic blockage of normal fluid circulation within the eye. Increased pressure within the eye can cause damage to the optic nerve and eventual blindness. Glaucoma is the leading cause of blindness. Symptoms include decreased vision, halos around lights (worse at night) and mild chronic headaches. Treatment is generally with beta-blocker eyedrops. Synonym: chronic glaucoma, compensated glaucoma, simple glaucoma, glaucoma simplex. (22 Sep 2002) |
