filament [fil´ah-ment]

1. a delicate fiber or thread.

2. in an x-ray tube, the wire (cathode) that makes electrons available for interaction with the anode when it is heated to incandescence to form an electron cloud.

actin filament one of the thin contractile filaments in a myofibril, composed mainly of actin; each actin filament is surrounded by three myosin filaments.

myosin filament one of the thick contractile filaments in a myofibril, composed mainly of myosin; each myosin filament is surrounded by six actin filaments.

beard filament

structures of the beard of the male turkey are neither hairs nor feathers but have some of the characteristics of both.

filament control

in an x-ray machine this controls the filament current in the x-ray tube. The size of the current and its duration are controlled in this way.

filament current

in an x-ray machine the strength of the current to the filament is varied by the use of a filament or stepdown transformer.

filament focal spot size

the focal spot of the x-ray beam should be as small as possible to give maximum sharpness and clarity. Its size is determined by the size of the filament opposite that generates the beam, the anode angle and other factors.

intermediate filament

non-contractile elements in the supportive structure of cytoplasm.
