Chapter F07 Glossary Flashcards
electrode of an electro therapy device that is used on the area to be treated
active electrode
rapid and interrupted current, flowing first in one direction and then in the opposite direction; produced by mechanical means and changes directions 60 times per second
alternating current
unit that measures the strength of an electric current
ampere
process of infusing an alkaline (negative) product into the tissues from the negative pole towards the positive pole
anaphoresis
positive electrode of an electrotherapy device; it is usually red and is marked with a P or a +
anode
substances that speed up chemical reactions
catalyst
process of infusing an acidic (positive) product into deeper tissues using galvanic current form the positive pole toward the negative pole
cataphoresis
negative electrode of an electrotherapy device; it is usually black and marked with an N or a -.
cathode
switch that automatically interrupts or shuts off an electric circuit at the first sign of an overload
circuit breaker
the path of the negative and positive electric currents moving from the generating source through the conductors and back to the generating source
complete electric current
any material that conducts electricity
conductor
definition that requires avoiding certain treatments, procedures, or products to prevent undesirable side effects
contraindication
a form of anaphoresis; process used to soften and emulsify grease deposits and blackehads in the hair follicles
disincrustation
constant, even flowing current that flows in one direction only and is produced by chemical means (ex: batteries)
direct current
flow of electricity along a conductor
electric current
the movement of electrons from one atom to another along a conductor
electricity
aka probe; applicator for directing electric current from an electrotherapy device to the client’s skin
electrode
name given to all of the forms of energy )or radiation) that exist
electromagmetic spectrum
use of electrical currents to treat the skin
electrotherapy
prevents excessive current from passing through a circuit
fuse
constant and direct current, having a positive and negative pole, that produces chemical changes when it passes through the tissue and fluids of the body.
galvanic current
completes an electric circuit and carries the current safely away
grounding
protects from electrical shock by interrupting a household circuit when there is a leak in the circuit
ground fault interrupter
opposite pole from the active electrode
inactive electrode
invisible light with longer wavelengths, deeper penetration, less energy, and more heat production than visible light; makes up 60% of natural sunlight
infrared light
apparatus that changes direct current to alternating current
inverter
light at either end of the visible spectrum of light that is invisible to the naked eye
invisible light
process of infusing water-soluble products into the skin with the use of electric current, such as the use of positive and negative poles of a galvanic machine
iontophoreses
1,000 watts. The electricity in your house
kilowatt
aka phototherapy; the application of light rays to the skin for the treatment of wrinkles, capillaries, pigmentation, or hair removal
light therapy
an extremely low level of electricity that mirrors the body’s natural electrical impulses
microcurrent
1/1,000 of an ampere; the current used for facial and scalp treatments
milliampere
currents used in electrical facial and scalp treatments
modalities
aka insulator; a material that does not transmit electricity
nonconductor
unit that measures the resistance of an electric current
ohm
positive or negative poles of an electric current
polarity
apparatus that changes alternation current to direct current
rectifier
aka violet ray; thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments
tesla high frequency current
light that has a short wavelength (giving it higher energy) is less penetrating than visible light, causes chemical reactions to happen more quickly than visible light, produces less heat than visible light, and kills germs
ultraviolet light
the part of the electromagnetic spectrum that can be seen; visible light makes up only 33% of natural sunlight
visible light
abbreviated as V aka voltage; unit that emasures the pressure or force that pushes electric current forward through a conductor
volt
measures how much electric energy is being used in one second
watt
measurement of the distance between two wavelengths
waveform
distance between successive peaks of electromagnetic waves
wavelength
