| Kuhne | Wilhelm (Willy) F., German physiologist and histologist, 1837-1900. See: Kuhne's fibre, Kuhne's methylene blue, Kuhne's phenomenon, Kuhne's plate, Kuhne's spindle. (05 Mar 2000) |
|---|---|
| Kuhne's methylene blue | Methylene blue in absolute alcohol and phenol solution. (05 Mar 2000) |
| Kuhne's phenomenon | When a constant current is passed through a muscle, an undulation is seen to pass from the positive to the negative pole. (05 Mar 2000) |
| Kuhne's plate | The endplate of a motor nerve fibre in a muscle spindle. (05 Mar 2000) |
| Kuhne's spindle | A fusiform end organ in skeletal muscle in which afferent and a few efferent nerve fibres terminate; it contains from 3 to 10 striated muscle fibres (intrafusal fibres) that are much smaller than the ordinary muscle fibres, are separated from them by a capsule that encloses the organ, and are innervated by the thin axon of a gamma motoneuron (gamma motor fibre); the sensory endings that occur on the intrafusal fibres are either annulospiral or flower spray endings; this sensory end organ is particularly sensitive to passive stretch of the muscle in which it is enclosed. Synonym: Kuhne's spindle, muscle spindle. (05 Mar 2000) |
| 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) |
| glaucomatous nerve-fibre bundle scotoma | See: caecocentral scotoma. (05 Mar 2000) |
| 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) |
