filament,

in astronomy: see chromospherechromosphere
[Gr.,=color sphere], layer of rarefied, transparent gases in the solar atmosphere; it measures 6,000 mi (9,700 km) in thickness and lies between the photosphere (the sun's visible surface) and the corona (its outer atmosphere).

Filament

A very thin tungsten wire inside an incandescent light. When heated, it glows and emits light.

filament

[′fil·ə·mənt]
(astronomy)
A prominence, seen as a dark marking on the solar disk.
(botany)
The stalk of a stamen which supports the anther.
A chain of cells joined end to end, as in certain algae.
(electricity)
Metallic wire or ribbon which is heated in an incandescent lamp to produce light, by passing an electric current through the filament.
(electronics)
A cathode made of resistance wire or ribbon, through which an electric current is sent to produce the high temperature required for emission of electrons in a thermionic tube. Also known as directly heated cathode; filamentary cathode; filament-type cathode.
(invertebrate zoology)
A single silk fiber in the cocoon of a silkworm.
(metallurgy)
A long, flexible metal wire drawn very fine.
(science and technology)
A long, flexible object with a small cross section.
(textiles)
A single continuous manufactured fiber which is extruded from a spinneret and joined with others to make a thread.

filament

An incandescent lamp filament whose form and construction are designated by a letter: S, straight wire; C, coil; CC, coiled coil.

1991) Sliding distance between actin and myosin filaments per ATP molecule hydrolysed in skinned muscle fibres.
Ultimately, Z discs on both sides of A band seem to be moved toward the center of A band but actually myosin filament slide toward origin end, and in the other half of each sarcomere (which is toward insertion end) actin filaments slide over myosin filament toward origin end of the muscle.
Therefore, we proposed a new theory that Z discs and actin filaments in the half part of each sarcomere, which is toward origin end of muscle fiber, are not pulled toward the center of myosin filament, instead myosin filament slide toward origin end.
4] The sliding filament theory was based on the observation that there are two separate sets of filament actin and myosin located differently with myosin filaments in A band, and on electron microscopy there are two interdigitating sets of filament and length of A band does not change during contraction.
