What is the black cord and plug of the negative electrode on a galvanic machine called?

1. Anode

2. Cathode

3. Electrode

4. Ground Wire

The correct answer is: Cathode

The black cord and plug of the negative electrode on a galvanic machine is referred to as the cathode. In the context of electrotherapy, the cathode is the electrode through which electrons enter the body, promoting negative reactions in tissues. The negative electrode has various effects, such as more alkaline reactions, which can aid in conditions like inflammation and the reduction of excess fluid. The use of the term "cathode" is consistent in electrotherapy practices, where it is commonly associated with negative polarity currents. Understanding the function of the cathode versus the anode is crucial for effective treatments, as the anode is the positive electrode, promoting different physiological reactions. Recognizing the distinction between the components of a galvanic machine, including the function of the electrodes, is fundamental for cosmetology professionals who utilize electrical modalities in their practice, as it directly relates to the outcomes of various treatments.
