| fila olfactoria | Collective term denoting the numerous olfactory filaments: slender fascicles each composed of the thin, unmyelinated axons of 8 to 12 of the bipolar olfactory receptor cells in the olfactory portion of the nasal mucosa; the olfactory filaments pass through the cribriform plate of the ethmoid bone and enter the olfactory bulb, where they terminate in synaptic contact with mitral cells, tufted cells, and granule cells. See: olfactory tract. Synonym: nervi olfactorii, fila olfactoria, first cranial nerve, nerve of smell, olfactory fila. (05 Mar 2000) |
| fila radicularia | |
| filaceous | Synonym: filamentous. Origin: L. Filum, a thread (05 Mar 2000) |
| filaggrin | <molecular biology> Basic protein components of keratohyalin granules of the suprabasal cells of the skin. Family of intermediate filament associated cationic proteins found in mammalian epidermis. Bundle cytokeratin filaments. Various sizes in different species (16 kD bovine, 26 kD mouse, 35 kD man, 45 kD rat). (10 Mar 1998) |
| filamen | A high-molecular-weight, actin-binding protein that is part of the intracellular filamentous structure of fibroblastic cells; its distribution in cells is derived from its interaction with polymerised actin. (05 Mar 2000) |
| filament | See: thick filaments, thin filaments, intermediate filaments and microfilaments. (18 Nov 1997) |
| 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) |
| filament-nonfilament count | A differential count of the number of neutrophils showing nuclear division and those showing no such division. (05 Mar 2000) |
| filamentary keratitis | A condition characterised by the formation of epithelial filaments of varying size and length on the corneal surface. Synonym: keratitis filamentosa. (05 Mar 2000) |
| filamentary keratopathy | Formation of fine elongations of corneal epithelium in inflammation, oedema, and degenerative states. (05 Mar 2000) |
| filamentous | <cell biology> In the form of very long rods, many times longer than wide. (10 Mar 1998) |
| filamentous bacterial viruses | Deoxyribonucleoproteins that "infect" and replicate in Gram-negative bacteria having sex pili and that, unlike bacteriophage, are released from infected bacteria without damage to the cell; they seem to be of two kinds, one of which has a specificity for F pili and the other for I pili. Synonym: fibrous bacterial viruses. (05 Mar 2000) |
| filamentous bacteriophage | <molecular biology> A type of single-stranded DNA bacteriophage (virus which infects bacteria) that has a capsid which is long and thin, like a filament. Examples include the viruses F1 and M13. (10 Mar 1998) |
| filamentous colony | In bacteriology, a colony composed of long, interwoven, irregularly disposed threads. (05 Mar 2000) |
