| angiolithic degeneration | Calcareous degeneration of the walls of the blood vessels. (05 Mar 2000) |
|---|---|
| ascending degeneration | Retrograde degeneration of an injured nerve fibre; i.e., toward the nerve cell of the fibre, degeneration cephalad to a spinal cord lesion. (05 Mar 2000) |
| atheromatous degeneration | Focal accumulation of lipid material (atheroma) in the intima and subintimal portion of arteries, eventually resulting in fibrous thickening or calcification. (05 Mar 2000) |
| axonal degeneration | A type of peripheral nerve fibre response to insult, wherein axon death and subsequent breakdown occurs, with secondary breakdown of the myelin sheath associated; caused by focal injury to peripheral nerve fibres; often referred to as wallerian degeneration. Synonym: axon degeneration. (05 Mar 2000) |

Synonym: axon degeneration. (05 Mar 2000) |
| ballooning degeneration | A phenomenon observed especially in cells that are infected with certain viruses, resulting in conspicuous swelling of the cell and cytoplasmic vacuolation. (05 Mar 2000) |
| basophilic degeneration | Blue staining of connective tissues when haematoxylin-eosin stain is used; found in such conditions as solar elastosis. (05 Mar 2000) |
| calcareous degeneration | In a precise sense, not a degenerative process per se, but the deposition of insoluble calcium salts in tissue that has degenerated and become necrotic, as in dystrophic calcification. (05 Mar 2000) |
| carneous degeneration | Necrosis, with staining by haemoglobin, which may occur in uterine myomas, especially during pregnancy; marked by softening and a red colour resembling partly cooked meat. Synonym: carneous degeneration. (05 Mar 2000) |
| vacuolar degeneration | Formation of nonlipid vacuoles in cytoplasm, most frequently due to accumulation of water by cloudy swelling. (05 Mar 2000) |
| macular degeneration | <ophthalmology> Breakdown or damage to a portion of the retina known as the macula. Symptoms include blurring of vision (in central visual field), colours appear dim and difficulty reading or performing work up close. (27 Sep 1997) |
| reaction of degeneration | The electrical reaction in a degenerated nerve and the muscles supplied by it; characterised by absence of response to both galvanic and faradic stimulus in the nerve and to faradic stimulus in the muscles; the muscles may still respond to galvanic stimulation, but the cathodal closing contraction is greater than the anodal closing contraction, the reverse of normal. (05 Mar 2000) |
| marginal corneal degeneration | Bilateral opacification and vascularization of the periphery of the cornea, progressing to formation of a gutter and ectasia. Synonym: ectatic marginal degeneration of cornea. (05 Mar 2000) |
| parenchymatous degeneration | Swelling of cells due to injury to the membranes affecting ionic transfer; causes an accumulation of intracellular water. Synonym: albuminous swelling, granular degeneration, hydropic degeneration, parenchymatous degeneration. (05 Mar 2000) |
| red degeneration | Necrosis, with staining by haemoglobin, which may occur in uterine myomas, especially during pregnancy; marked by softening and a red colour resembling partly cooked meat. Synonym: carneous degeneration. (05 Mar 2000) |
