| filamin | <protein> A protein that binds to F actin, cross linking it to form an isotropic network, the binding does not require Ca. It was originally isolated from smooth muscle and is a homodimer 2 x 250 kD. Similar to actin binding protein (ABP) from leucocytes. (18 Nov 1997) |
| filander | <zoology> A species of kangaroo (Macropus Brunii), inhabiting new Guinea. Source: Websters Dictionary (01 Mar 1998) |
| filanders | <veterinary> A disease in hawks, characterised by the presence of small threadlike worms, also of filaments of coagulated blood, from the rupture of a vein. Synonym: backworm. Origin: F. Filandres, fr. L. Filum thread. Source: Websters Dictionary (01 Mar 1998) |
| filar | <optics> Of or pertaining to a thread or line; characterised by threads stretched across the field of view; as, a filar microscope; a filar micrometer. Origin: L. Filum a thread. Source: Websters Dictionary (01 Mar 1998) |
| filar eyepiece | |
| filar mass | A filamentous plasmatic material, beaded with granules, demonstrable by means of vital staining in the immature red blood cells. Synonym: alpha substance, filar mass, filar substance, substantia reticularis, substantia reticulofilamentosa. Synonym: reticular formation. (05 Mar 2000) |
| filar micrometer | An ocular micrometer with a line moved by a ruled drum such that a movement of the line of 5 um or less may be made in relation to fixed parallel lines. (05 Mar 2000) |
| filar micrometre | <microscopy> An eyepiece equipped with a fiducial line in its focal plane that is movable by means of a calibrated micrometre screw in order to make accurate measurements of length. Synonym: filar eyepiece. (05 Aug 1998) |
| filar micrometre ocular | <microscopy> A micrometre ocular with crossed lines which can be simultaneously focused in and moved across the field by means of a micrometre screw. The amount of displacement can be read in 0.01 steps on the micrometre drum head. This makes a very delicate measuring device, since calibration of the micrometre scale by means of a stage micrometre gives values for each interval on the drum head which are much less than the resolving power of the highest-aperture objectives.

| filar substance | A filamentous plasmatic material, beaded with granules, demonstrable by means of vital staining in the immature red blood cells. Synonym: alpha substance, filar mass, filar substance, substantia reticularis, substantia reticulofilamentosa. Synonym: reticular formation. (05 Mar 2000) |
| filaria | <zoology> A genus of slender, nematode worms of many species, parasitic in various animals. See: Guinea worm. Origin: NL, fr. L. Filum a thread. Source: Websters Dictionary (01 Mar 1998) |
| filarial | Pertaining to a filaria (or filariae), including the microfilaria stage. (05 Mar 2000) |
| filarial arthritis | Arthritis occurring in filariasis, probably due to extravasation of lipid-rich lymph resembling chyle into the joint space. (05 Mar 2000) |
| filarial dermatosis | A disease of sheep on high mountain ranges during the summer caused by larvae of the filarial worm, Elaeophora schneideri, which localise chiefly on the head, causing intense itching and loss of wool. Synonym: sorehead. (05 Mar 2000) |
