| keratin filaments | A class of intermediate filament's that form a network within epithelial cells and anchor to desmosomes, thus imparting tensile strength to the tissue. Synonym: cytokeratin filaments. (05 Mar 2000) |

| mucopolysaccharide keratin dystrophy | A histologic finding seen in the surface epithelium of oral inflammatory fibrous hyperplasia, consisting of homogeneous eosinophilic pools of material in the superficial spinous layer. (05 Mar 2000) |
|---|---|
| keratin | <protein> A protein that is a primary constituent of hair, nails and skin. (27 Sep 1997) |
| keratin pearl | A focus of central keratinization within concentric layers of abnormal squamous cells; seen in squamous cell carcinoma. Synonym: epithelial nest, epithelial pearl, squamous pearl. (05 Mar 2000) |
| actin filament | One of the contractile elements in muscular fibres and other cells; in skeletal muscle, the actin filament's are about 5 nm wide and 100 um long, and attach to the transverse Z filament's. (05 Mar 2000) |
| axial filament | The central filament of a flagellum or cilium; with the electron microscope it is seen as a complex of nine peripheral diplomicrotubules and a central pair of microtubules. Synonym: axoneme. (05 Mar 2000) |
| bipolar filament | <cell biology> Filaments that have opposite polarity at the two ends, classic example is the thick filament of striated muscle. (18 Nov 1997) |
| parabasal filament | Term formerly used for rhizoplast. (05 Mar 2000) |
| glial filament | <cell biology> Intermediate filaments of glial cells, made of glial fibrillary acidic protein. (17 Dec 1997) |
| myosin filament | One of the contractile elements in skeletal, cardiac, and smooth muscle fibres; in skeletal muscle, the filament is about 10 nm thick and 1.5 um long. (05 Mar 2000) |
| sliding filament hypothesis | The theory that the contracting muscle shortens because two sets of filaments slide past each other. (05 Mar 2000) |
| sliding filament model | <cell biology> Generally accepted model for the way in which contraction occurs in the sarcomere of striated muscle, by the sliding of the thick filaments relative to the thin filaments. (18 Nov 1997) |
| spermatic filament | A spermatozoon, especially the tail of a spermatozoon. (05 Mar 2000) |
| 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) |
| thick filament | <cell biology> Bipolar myosin II filaments (12-14nm diameter, 1.6m long) found in striated muscle. Myosin filaments elsewhere are often referred to as thick filaments, although their length may be considerably less. The myosin heads project from the thick filament in a regular fashion. There is a central bare zone without projecting heads, the core being formed from antiparallel arrays of LMM regions of the myosin heavy chains. Thick filaments will self assemble in vitro under the right ionic conditions. (18 Nov 1997) |
