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.
