| intermediate filament | <cell biology> A class of cytoplasmic filaments of animal cells so named originally because their diameter (nominally 10 nm) in muscle cells was intermediate between thick and thin filaments. Unlike microfilaments and microtubules, the protein sub units of intermediate filaments show considerable diversity and tissue specificity. See: cytokeratins, desmin, glial fibrillary acidic protein, neurofilament proteins, nestin and vimentin (18 Nov 1997) |
|---|---|
| intermediate filament proteins | Filaments 7-11 nm in diameter found in the cytoplasm of all cells. Many specific proteins belong to this group, e.g., desmin, vimentin, prekeratin, decamin, skeletin, neurofilin, neurofilament protein, and glial fibrillary acid protein. (12 Dec 1998) |
| thin filament | Filaments 7-9nm diameter attached to the Z discs of striated muscle, have opposite polarity in each half sarcomere. Built of F actin with associated tropomyosin and troponin. (18 Nov 1997) |
| Z filament | The thin zig-zag structure at the Z line of striated muscle fibres to which the actin filament's attach. (05 Mar 2000) |
| filament | See: thick filaments, thin filaments, intermediate filaments and microfilaments. (18 Nov 1997) |
| filament-nonfilament count | A differential count of the number of neutrophils showing nuclear division and those showing no such division. (05 Mar 2000) |
| filament polymorphonuclear leukocyte | Any mature polymorphonuclear leukocyte, especially a neutrophilic leukocyte, in which the lobes of the nucleus are interconnected with a thin strand or filament of chromatin. (05 Mar 2000) |
