| gray level also gray value | <microscopy> The brightness of pixels in a digitised video image, commonly expressed in integers ranging from 0 (black) to 255 (white) for an 8-bit digital signal. (05 Aug 1998) |

| articular crescent | A crescent-shaped intra-articular fibrocartilage found in certain joints. Synonym: meniscus articularis, articular crescent, intra-articular cartilage. (05 Mar 2000) |
| malarial crescent | The male or female gametocyte(s) of Plasmodium falciparum, whose presence in human red blood cells is diagnostic of falciparum malaria. Synonym: crescent, sickle form. Myopic crescent, a white or grayish white crescentic area in the fundus of the eye located on the temporal side of the optic disk; caused by atrophy of the choroid, permitting the sclera to become visible. Synonym: myopic conus. Sublingual crescent, the crescent-shaped area on the floor of the mouth formed by the lingual wall of the mandible and the adjacent part of the floor of the mouth. (05 Mar 2000) |
| glomerular crescent | Proliferated epithelial cells partly encircling a renal glomerulus; it occurs in glomerulonephritis. (05 Mar 2000) |
| grey crescent | <biology> A region near the equator of the surface in the fertilized egg of various amphibia, often of greyish colour, that appears to contain special morphogenetic properties. (18 Nov 1997) |
| crescent | 1. Any figure of the shape of the moon in its first quarter. 2. The figure made by the gray columns or cornua on cross-section of the spinal cord. Synonym: malarial crescent. Origin: L. Cresco, pp. Cretus, to grow (05 Mar 2000) |
| crescent cell | <haematology, pathology> An erythrocyte that changes from the normal discoid shape to a sickled shape when the oxygen tension is low. The pesence of these cells indicates that the patient is homozygotes for the allele that codes for haemoglobin S and that the patient has sickle cell anaemia. (18 Nov 1997) |
| crescent cell anaemia | <haematology> Disease common in races of people from areas in which malaria is endemic. The cause is a point mutation in the allele that codes for the beta chain of haemoglobin with a substitution of (valine for glutamic acid at position 6. The defective haemoglobin (HbS) crystallizes readily at low oxygen tension. In consequence, erythrocytes from homozygotes change from the normal discoid shape to a sickled shape when the oxygen tension is low and these sickled cells become trapped in capillaries or damaged in transit, leading to severe anaemia. In heterozygotes, the disadvantages of the abnormal haemoglobin are apparently outweighed by increased resistance to Plasmodium falciparum malaria, probably because parasitised cells tend to sickle and are then removed from circulation. Symptoms include joint pain, acute abdominal pain, and ulcerations of the lower extremities. Origin: Gr. Haima = blood (18 Nov 1997) |
| anterior gray column | The central gray matter of the spinal cord surrounding the central canal. Synonym: substantia intermedia centralis et lateralis, anterior gray column, Stilling's gelatinous substance, substantia gelatinosa centralis. (05 Mar 2000) |
| matter, gray | The cortex of the brain which contains nerve cell bodies. The gray matter is as opposed to the white matter, the part of the brain that contains myelinated nerve fibres. The gray matter is so named because it in fact appears gray. In the mysterious affair at styles (1920), agatha christie first quoted the fictional belgian detective hercule poirot in regard to his gray matter: 'this affair must be unravelled from within.' he tapped his forehead. 'these little grey cells. It is up to them as you say over here.' (12 Dec 1998) |
| central gray substance | In general: the predominantly small-celled gray matter adjoining or surrounding the central canal of the spinal cord and the third and fourth ventricles of the brainstem, in particular: the thick sleeve of gray matter surrounding the cerebral sylvian aqueduct in the midbrain, rostrally continuous with the posterior nucleus of the hypothalamus; in sections stained for myelin it stands out from the adjoining tectum and tegmentum by the poverty of its myelinated fibres. Synonym: substantia grisea centralis. (05 Mar 2000) |
| periaqueductal gray | Central gray matter surrounding the cerebral aqueduct in the mesencephalon. Physiologically it is probably involved in rage reactions, the lordosis reflex, feeding responses, bladder tonus, and pain. (12 Dec 1998) |
| Gray | <radiobiology, unit> The new international system unit (SI unit) of absorbed dose of radiation (Gy), 1 Gy = 1 J kg-1 = 100 rad. (16 Dec 1997) |
| gray cataract | A cataract of gray colour, usually seen in senile, mature, or cortical cataract. (05 Mar 2000) |
| gray collie syndrome | An autosomal recessive, inherited immunodeficiency of gray collie dogs characterised by overwhelming recurrent bacterial infections, bleeding, and coat colour dilution. Synonym: gray collie syndrome. (05 Mar 2000) |
