cathode

 [kath´ōd]
the electrode at which reduction occurs and to which cations are attracted. adj., adj cathod´ic.

cath·ode (Ca, C),

(kath'ōd),
The negative pole of a galvanic battery or the electrode connected with it; the electrode toward which positively charged ions (cations) migrate and are reduced, and into which electrons are fed from their source (anode or generator). Compare: anode.
Synonym(s): negative electrode
[G. kathodos, a way down, fr. kata, down, + hodos, a way]

1. The negative pole of a galvanic battery or the electrode connected with it; the electrode to which positively charged ions (cations) migrate.
Compare: anode
2. Negatively charged part of the x-ray tube head; it contains the tungsten filament.

cathode

a negatively charged electrode to which positively charged ions move. Compare ANODE.

Cathode

The negative electrode from which an electromagnetic current flows.

cathode (kath´ōd),

n a negative electrode from which electrons are emitted and to which positive ions are attracted. In radiographic tubes, the cathode usually consists of a helical tungsten filament, behind which a molybdenum reflector cup is located to focus the electron emission toward the target of the anode.
cathode ray tube (CRT),
n a vacuum tube in which a beam of electrons is focused to a small point on a luminescent screen and can be varied in position to form a pattern.

cathode

1. the negative electrode, from which electrons are emitted and to which positive ions are attracted.
2. the electrode through which current leaves a nerve or other substance.

cathode beam, cathode ray
the beam of electrons, accompanied by high electrical potential which flows from the cathode to the anode in the x-ray tube and interacts with the tungsten target to produce x-rays.
cathode filament
the source of electrons in the cathode tube that interacts with the anode target to produce x-rays.
