| OB | Oligoclonal Bands |
|---|
| Streeter's bands | The strands of amniotic tissue adherent to the embryo or foetus; they may cause constriction of embryonic limbs. See: congenital amputation. Synonym: amniotic adhesions, annular band, constriction ring, Simonart's bands, Simonart's ligaments, Simonart's threads, Streeter's bands. (05 Mar 2000) |

| Streeter, George | <person> U.S. Embryologist, 1873-1948. See: Streeter's bands, Streeter's developmental horizon(s). (05 Mar 2000) |
|---|---|
| Streeter's developmental horizon | A term borrowed from geology and archeology by Streeter to define 23 developmental stages in young human embryos, from fertilization through the first 2 months; each horizon spanned 2 to 3 days and emphasized specific anatomic characteristics, to avoid discrepancies in the determination of age and body dimensions. Origin: G.L. Streeter (05 Mar 2000) |
| A bands | The dark-staining anisotropic cross striations in the myofibrils of muscle fibres, comprising regions of overlapping thick (myosin) and thin (actin) filaments. Synonym: A disks, anisotropic disks, Q bands, Q disks. (05 Mar 2000) |
| amniotic bands | The strands of amniotic tissue adherent to the embryo or foetus; they may cause constriction of embryonic limbs. See: congenital amputation. Synonym: amniotic adhesions, annular band, constriction ring, Simonart's bands, Simonart's ligaments, Simonart's threads, Streeter's bands. (05 Mar 2000) |
| Baillarger's bands | Two laminae of white fibres that course parallel to the surface of the cerebral cortex and are visible as outer and inner line's in sections cut perpendicular to the surface; the line of Gennari in the calcarine cortex represents the outer of these lines. Synonym: Baillarger's bands. (05 Mar 2000) |
| bands of colon | teniae coli |
| matrix bands | Devices which provide an artificial temporary wall, or matrix, used in filling a prepared cavity. (12 Dec 1998) |
| Muehrcke's bands | <clinical sign> Apparent leukonychia with white bands parallel to lanula of the nails, seen in hypoalbuminaemia. Synonym: Muehrcke's bands. (05 Mar 2000) |
| Hunter-Schreger bands | Alternating light and dark lines seen in dental enamel that begin at the dentoenamel junction and end before they reach the enamel surface; they represent areas of enamel rods cut in cross-sections dispersed between areas of rods cut longitudinally. Synonym: Hunter-Schreger lines, Schreger's lines. (05 Mar 2000) |
| Simonart's bands | The strands of amniotic tissue adherent to the embryo or foetus; they may cause constriction of embryonic limbs. See: congenital amputation. Synonym: amniotic adhesions, annular band, constriction ring, Simonart's bands, Simonart's ligaments, Simonart's threads, Streeter's bands. (05 Mar 2000) |
| dense metaphyseal bands | <radiology> Normal variant, stress lines, heavy metal poisoning, treated rickets, scurvy, hypervitaminosis D (12 Dec 1998) |
| Q bands | <cell biology> The alternating bright and dull fluorescent bands seen on chromosomes under ultraviolet light after the chromosomes are stained with quinacrine. The Q stands for quinacrine, an agent used as an antimalarial agent and, in the laboratory, as a fluorescent dye. (12 Dec 1998) |
| Essick's cell bands | Groups of cells in the developing rhombencephalon which migrate in two bands, one of which eventually forms the inferior olivary nucleus and the arcuate nucleus, and the other the pontine nuclei. (05 Mar 2000) |
| longitudinal bands of cruciform ligament | <anatomy> Ligamentous slips forming the "upright" or vertical beam of the cruciform ligament. Synonym: fasciculi longitudinales ligamenti cruciformis atlantis. (05 Mar 2000) |
