| cerebellopontine angle | <anatomy, oncology> The angle between the cerebellum and the pons, a common site for the growth of acoustic neuromas. (16 Dec 1997) |
|---|---|
| cerebellopontine angle syndrome | <syndrome> A syndrome due most commonly to an acoustic tumour in the region between the cerebellum and pons, and marked by ataxia, nystagmus, tinnitus, deafness, disturbances of labyrinth function, and involvement of any of the cranial nerves, fifth, sixth, seventh, ninth, or tenth. (05 Mar 2000) |
| cerebellopontine angle tumour | This is a benign tumour of the 8th cranial nerve that affects approximately 1 out of 100,000 people. This tumour arises from the myelin forming Schwann cells that coat the 8th cranial nerve (acoustic nerve). Clinical presentation usually includes hearing deficit. Diagnosis can be made with auditory evoked potentials and/or MRI scanning of the brain. Vertigo and tinnitus may be associated symptoms. Surgical removal of this tumour involves dissection, cautery and obliteration with laser. Causes: acoustic neuroma (90%), meningioma (7%), epidermoid (3%), uncommon: metastasis, trigeminal neuroma, arachnoid cyst, aneurysm, vertebro-basilar dolichoectasia (12 Dec 1998) |
| 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) |
