| intraocular neuritis | Inflammation of the retinal portion of the optic nerve. (05 Mar 2000) |
|---|---|
| occipital neuritis | See: posttraumatic neck syndrome. (05 Mar 2000) |
| optic neuritis | <pathology> Inflammation of the optic nerve. This may occur secondary to a wide variety of causes: multiple sclerosis, posterior uveitis, vascular lesions of the optic nerve (interruption of blood supply to the optic nerve), temporal arteritis, central retinal artery occlusion, methyl alcohol poisoning, drug side effects and acute demyelinative disease of the optic nerves (destruction of optic nerve sheath). (27 Sep 1997) |
| Eichhorst's neuritis | Inflammation of the connective tissue framework of a nerve. Synonym: Eichhorst's neuritis. (05 Mar 2000) |
| toxic neuritis | Neuritis caused by an endogenous or exogenous toxin. (05 Mar 2000) |
| endemic neuritis | <disease> An endemic form of polyneuritis (nerve inflammation), due to an unbalanced diet, with a deficiency of vitamin B1(thiamin). Common in those who chronically abuse alcohol. (11 Jan 1998) |
| traumatic neuritis | Nerve lesion following an injury. (05 Mar 2000) |
| fallopian neuritis | Paralysis of the facial muscles, usually unilateral, due to either a lesion involving the nucleus or the facial nerve peripheral to the nucleus (peripheral facial paralysis) or a supranuclear lesion in the cerebrum or upper brainstem (central facial paralysis). With latter, facial weakness is usually partial and the upper portion of the face is relatively spared, due to bilateral cortical connections. (12 Dec 1998) |
| Leyden's neuritis | Fatty degeneration of the fibres of the affected nerve. (05 Mar 2000) |
| abnormalities, radiation-induced | Congenital changes in the morphology of organs produced by exposure to ionizing or non-ionizing radiation. (12 Dec 1998) |
| accidents, radiation | Accidental dispersal of radioactive materials from a radiation source. Accidents at nuclear reactors can involve large groups of the population from dispersion of radioactivity into the environment and through fallout or a few individuals with high injurious doses. (12 Dec 1998) |
| acoustic radiation | The fibres that pass from the medial geniculate body to the transverse temporal gyri of the cerebral cortex by way of the sublentiform part of the internal capsule. Synonym: radiatio acustica. (05 Mar 2000) |
| acute radiation syndrome | <syndrome> A syndrome caused by exposure of the body to large amounts of radiation, (e.g., from certain forms of therapy, accidents, and nuclear explosions; it is divided into three major forms which are, in ascending order of severity, the haematogic, gastrointestinal, and central nervous system-cardiovascular forms; its clinical manifestations are divided into prodromal, latent, overt, and recovery stages. (05 Mar 2000) |
| adaptive radiation | <chemistry> The evolution of new speciesor sub-species to fill unoccupied ecological niches. (06 May 1997) |
| alpha radiation | <physics, radiobiology> The most easily absorbable type of radiation, it consists of a stream of alpha particles, doubly ionised helium nuclei which are electrically charged and produce intense ionisation in matter. Alpha radiation can be deflected in electromagnetic fields. (09 Oct 1997) |
