| 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) |
| crescentic | Shaped like a crescent. (05 Mar 2000) |
| crescentic glomerulonephritis | <nephrology, pathology> A relatively uncommon (affecting 1 out of 10,000 people) form of acute glomerulonephritis that results in damage within the glomerulus of the kidney. There is rapid loss of kidney function with the formation of crescents on microscopic analysis (kidney biopsy). This disorder may result in acute glomerulonephritis or nephrotic syndrome, but ultimately results in renal failure and end-stage renal disease. Symptoms include smoky coloured urine (pyuria), decreased urine output, swelling and hypertension. Any conditions which can cause a vasculitis increase the risk of this disorder. Some examples include lupus, Goodpasture's syndrome, Henoch-Schonlein purpura, IgA nephropathy, membranoproliferative glomerulonephritis, anti-glomerular basement membrane antibody disease, history for malignant tumours and exposure to hydrocarbon solvents.

| crescentic lobules of the cerebellum | Archaic term designation for lobulus semilunaris inferior and lobulus semilunaris superior. (05 Mar 2000) |

| cresol | HO-C6H4-CH3; hydroxytoluene; methylphenol;a mixture of the three isomeric cresols, o-, m-, and p-cresol, obtained from coal tar. Its properties are similar to those of phenol, but it is less poisonous; used as an antiseptic and disinfectant. Synonym: tricresol. (05 Mar 2000) |
| cresol red | <chemical> A reddish-brown powder which can be dissolved in water or alcohol that has the chemical formula of C21H18O5S. The dissolved compound has different colours depending on the pH, when the pH is 7.2 it is yellow, when the pH is 8.8 it is red, and when the pH is 2-3 it is orangish. As a result, it is used as an acid-base indicator. It is also used as a stain in the study of histology. (09 Oct 1997) |
| cresolase | <enzyme> An enzyme of the oxidoreductase class that catalyses the reaction between l-tyrosine, l-dopa, and oxygen to yield l-dopa, dopaquinone, and water. It is a copper protein that acts also on catechols, catalyzing some of the same reactions as catechol oxidase. Chemical name: Monophenol,L-dopa:oxygen oxidoreductase Registry number: EC 1.14.18.1 (12 Dec 1998) |
| crest | 1. A ridge, especially a bony ridge. See: crista. 2. The ridge of the neck of a male animal, especially of a stallion or bull. 3. Feathers on the top of a bird's head, or fin rays on the top of a fish's head. Synonym: crista. Origin: L. Crista (05 Mar 2000) |
| crest of alveolar ridge | The top of the alveolar ridge or residual ridge; the highest continuous surface of the ridge, but not necessarily the centre of the ridge. (05 Mar 2000) |
| crest of cochlear opening | The edge of the opening of the cochlear window to which the secondary tympanic membrane is attached. Synonym: crista fenestrae cochleae, crest of cochlear opening. (05 Mar 2000) |
