| 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) |
| 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) |
| Adair-Koshland-Nemethy-Filmer model | <biochemistry, chemistry> A model to explain the allosteric form of cooperativity; in this model, in the absence of ligands, the protein exists in only one conformation; upon binding, the ligand induces a conformational change that may be transmitted to other subunits. Synonym: Adair-Koshland-Nemethy-Filmer model, induced fit model. (05 Mar 2000) |
| additive model | A model in which the combined effect of several factors is the sum of the effects that would be produced by each of the factors in the absence of the others. (05 Mar 2000) |
| age-structured model | <epidemiology> A mathematical model which take into consideration the division of the host population into different age classes. Such models can used to consider the consequences of such factors as age-dependent infection, morbidity or mortality rates or of age-specific vaccination schedules. (05 Dec 1998) |
| animal model | Study in a population of laboratory animals that uses conditions of animals analogous to conditions of humans to simulate processes comparable to those that occur in human populations. (05 Mar 2000) |
| Bingham model | A model representing the flow behaviour of a Bingham plastic, in the idealised case. (05 Mar 2000) |
| biomedical model | A conceptual model of illness that excludes psychological and social factors and includes only biological factors in an attempt to understand a person's medical illness or disorder. (05 Mar 2000) |
