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.

The electrical interconnections are thin, and narrow, in filamentary serpentine shapes; they deform as tiny springs during the stretching process.
However, the question of cocontinuity is a more difficult issue and the two-dimensional surface offers only hints, such as the appearance of intertwined channels, filamentary segments, and branch points.
