| posterior cerebral commissure | A thin band of white matter, crossing from side to side beneath the habenula of the pineal body and over the aditus ad aqueductum cerebri; it is largely composed of fibres interconnecting the left and right pretectal region and related cell groups of the midbrain; dorsally, it marks the junction of the diencephalon and mesencephalon. Synonym: posterior cerebral commissure. (05 Mar 2000) |
|---|---|
| habenular commissure | The connection between the right and left habenular nuclei; the decussation of fibres of the two striae medullares, forming the dorsal portion of the peduncle of the pineal body. Synonym: commissure of habenulae, habenular commissure. (05 Mar 2000) |
| posterior labial commissure | A slight fold uniting the labia majora posteriorly in front of the anus. Synonym: commissura labiorum posterior. (05 Mar 2000) |
| hippocampal commissure | The triangular subcallosal plate of commissural fibres resulting from the converging of the right and left fornix bundles which exchange numerous fibres and which curve back in the contralateral fornix to end in the hippocampus of the opposite side. Synonym: commissura hippocampi, commissure of fornix, delta fornicis, hippocampal commissure, psalterium, transverse fornix. (05 Mar 2000) |
| labial commissure | Junction of upper and lower lip which occurs at corner of mouth. See: angle of mouth. (05 Mar 2000) |
| lateral palpebral commissure | The union of the upper and lower eyelids adjacent to the lateral angle. Synonym: commissura palpebrarum lateralis. (05 Mar 2000) |
| blue white colour selection | <molecular biology, procedure> Method for identifying bacterial clones containing plasmids with inserts. Many modern vectors have their polycloning site within a part of the LacZ gene encoding _ galactosidase, which provides _ complementation in an appropriate mutant E. Coli strain. This means that a re ligated (empty) vector will produce blue colonies when grown on plates containing IPTG and X gal, but colonies with a substantial insert in their plasmid's polycloning site are unable to produce functional _ galactosidase and so produce white colonies. (16 Dec 1997) |
| Bouffardi's white mycetoma | <dermatology> A form of mycetoma common in India and found occasionally in Somalia, caused by the organism Streptomyces somaliensis; in this variety, the muscles, tendons, and bones of the foot are destroyed by the disease process; numerous draining sinuses discharge yellowish grains, clustered like fish roe. (05 Mar 2000) |
| Brumpt's white mycetoma | Mycetoma caused by Pseudallescheria boydii, occurring in temperate and subtropical areas in India; small, white to yellow, hard to soft granules are discharged through the draining sinuses. (05 Mar 2000) |
| ventral white column | A narrow band of white substance bordering on the anterior median fissure of the spinal cord in front of the anterior gray commissure, and consisting of nerve fibres crossing over from one half of the spinal cord to the other. Synonym: commissura alba, anterior white commissure, commissura ventralis alba, ventral white column. (05 Mar 2000) |
| matter, white | The part of the brain that contains myelinated nerve fibres. The white matter is white because it is the colour of myelin, the insulation covering the nerve fibres. The white matter is as opposed to the gray matter (the cortex of the brain which contains nerve cell bodies). (12 Dec 1998) |
| May-White syndrome | <syndrome> Progressive myoclonus epilepsy with lipomas, deafness, and ataxia; probably a familial form of mitochondrial encephalomyopathy. (05 Mar 2000) |
| Vincent's white mycetoma | Mycetoma caused by Actinomadura madurae and occurring in North Africa, India, the Argentine, and Cuba. (05 Mar 2000) |
| methylene white | The reduced and colourless form of methylene blue. Synonym: methylene white. (05 Mar 2000) |
| water-white | <botany> A vinelike plant (Vitis Caribaea) growing in parched districts in the West Indies, and containing a great amount of sap which is sometimes used for quenching thirst. Source: Websters Dictionary (01 Mar 1998) |
