electrode

 [e-lek´trōd]
either of two terminals of an electrically conducting system or cell; specifically, the uninsulated portion of a lead that is in direct contact with the body.
active electrode therapeutic electrode.
calomel electrode one capable of both collecting and giving up chloride ions in neutral or acidic aqueous media, consisting of mercury in contact with mercurous chloride; used as a reference electrode in pH measurements.
depolarizing electrode an electrode that has a resistance greater than that of the portion of the body enclosed in the circuit.
hydrogen electrode an electrode made by depositing platinum black on platinum and then allowing it to absorb hydrogen gas to saturation; used in determination of hydrogen ion concentration.
indifferent electrode one larger than a therapeutic electrode, dispersing electrical stimulation over a larger area.
point electrode an electrode having on one end a metallic point; used in applying current.
therapeutic electrode one smaller than an indifferent electrode, producing electrical stimulation in a concentrated area; called also active electrode.

ac·tive e·lec·trode

a small electrode with an exciting effect that is used to stimulate or record potentials from a localized area.

active electrode

Etymology: Gk, elektron, amber, hodos, way
an electrode that is applied at a specific point to produce stimulation in a concentrated area in electrotherapy or electrocautery.
