| rectified optics | <microscopy> Microscope lens system correcting the rotation of polarized light that takes place at high-incidence-angle interfaces between the polarizer and analyser. Rectification provides high extinction for polarized-light and Differential Interference Contrast microscopy at high numerical apertures, thus permitting bifringence or phase retardation combined with high in g low phase. (05 Aug 1998) |

| confocal optics | <microscopy> A (microscope) optical system in which the condenser and objective lenses both focus onto one single point in the specimen. Generally, the image of a pinhole source is focused onto a point in the specimen, and that point is focused by the objective lens onto a point detector or through a mask with a pinhole aperture. With confocal optics, the Abbe limit of resolution can be exceeded since only a limited region of the specimen is viewed at any onetime. (05 Aug 1998) |
| optics | That branch of physical science which treats of the nature and properties of light, the laws of its modification by opaque and transparent bodies, and the phenomena of vision. Origin: Cf. F. Optique, L. Optice, Gr. (sc). See Optic. Source: Websters Dictionary (01 Mar 1998) |
| electron optics | <study> The science that deals with propagation electrons, as light optics deals with that of light and its phenomena. Eye lens (see lens, eye). (05 Aug 1998) |
| argyrophilic fibre | Reticular connective tissue fibre's that react with silver salts and appear black microscopically. (05 Mar 2000) |
| bowel disorders and fibre | High fibre diets help delay the progression of diverticulosis and, at least, reduce the bouts of diverticulitis. In many cases, it helps reduce the symptoms of the Irritable Bowel Syndrome ( IBS ). It is generally accepted that a diet high in fibre is protective, or at least reduces the incidence, of colon polyps and colon cancer. (12 Dec 1998) |

| Reissner's fibre | A rodlike, highly refractive fibre running caudally from the subcommissural organ throughout the length of the central canal of the brainstem and spinal cord. (05 Mar 2000) |
| medullated nerve fibre | An axon enveloped by a myelin sheath formed by oligodendroglia cells (in brain and spinal cord) or Schwann cells (in peripheral nerves). Synonym: medullated nerve fibre. (05 Mar 2000) |
| reticular fibre | <cell biology> A fine fibre of reticulin found in the extracellular matrix. They are fibres of type III collagen which form the distinctive loose connective tissue stroma of embryonic tissues, mesenchyme, red pulp of the spleen, cortex and medulla of lymph nodes, and the haematopoietic compartments of bone marrow and comprise a substantial portion of the collagen fibres of the skin, blood vessels, synovial membrane, uterine tissue, and granulation tissue. They are characterised by their organization as a reticular meshwork of fine filaments and an affinity for silver and for periodic acid-Schiff stains. (17 Jul 2002) |
| retraction fibre | Thin projections from crawling cells associated with areas where the cell body is becoming detached from the substratum, but focal adhesions persist. Usually contain a bundle of microfilaments that are under tension. (18 Nov 1997) |
| rod fibre | A part of the rod cell of the retina that extends to either side of the cell body; the inner rod fibre terminates in the spherule, a synaptic ending located in the outer plexiform layer. (05 Mar 2000) |
| chromatic fibre | The coiled filament in which the genes are located, which extends the entire length of a chromosome and exhibits an intensely positive Feulgen test for DNA. Synonym: chromatic fibre. Origin: chromo-+ G. Nema, thread (05 Mar 2000) |
| Rosenthal fibre | An oval or elongated eosinophilic mass believed to represent a modified process of an astrocyte; seen in large numbers in certain slowly growing astrocytomas and areas of chronic reactive gliosis. (05 Mar 2000) |
| collagen fibre | An individual fibre that varies in diameter from less than 1 um to about 12 um and is composed of fibrils; the fibre's, which are usually arranged in bundles, undergo some branching and are of indefinite length; chemically the fibre is a glycoprotein, collagen, which yields gelatin upon boiling; they make up the principal element of irregular connective tissue, tendons, aponeuroses, and most ligaments, and occur in the matrix of cartilage and osseous tissue. Synonym: white fibre. (05 Mar 2000) |
| fibre optics | the transmission of light signals via glass fibers |
