electro-, electr-, electri-

(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)

Electronics in our lives consists of numerous tools

Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.

electrogoniometer
1. An electrical device for measuring angles of joints and their ranges of motions.
2. An instrument used to measure positions of flexion (the bending of an arm, leg, or other joint) and the extension of a hinge joint.
electrogram
1. Any record on paper or film made by an electrical event.
2. A record of changes in electrical activities or time variations in the atmospheric electric field for a given point.
3. A unipolar or bipolar record of the electric activity of the heart as recorded by electrodes within the cardiac chambers or on the epicardium; such as, the atrial electrogram, and the ventricular electrogram.
4. The graphic representation of electric events in living tissues; most commonly, an electrocardiogram or electroencephalogram.
electrograph
1. An electrical device for engraving a design on a metal plate which is used for printing patterns on fabrics or wallpaper.
2. An apparatus used to transmit pictures by electrical means; for example, by fax.
3. A graphic representation created by the movement of an electric current on sensitized paper or an electrically controlled writing instrument used in telecommunications.
electrographic
A reference to an electrical device for engraving a design on a metal plate which is used for printing patterns on fabrics or wallpaper.
electrographic technician
A health care provider with special training and experience to assist the physician in recording and analyzing muscle action potentials with the use of various electronic devices.
electrography
1. The process of copying an engraving on an electro-copper plate.
2. The branch of electrostatography in which electrostatic images are formed on an insulating medium without the aid of eledgromagnetic radiation.

It includes xeroprinting, where the charged image is permanent, as required for repetitive printing and electrographic recording, in which the charged image is formed by electric procedures.

3. Any technique involving the recording of electrical potentials in resting bodily tissues or organs, and of changes in these potentials during physiological or pathological activity.
electrogustometer
An apparatus for applying a direct electrical current to points on the tongue as a means of testing the sense of taste.

An anode (electrode to which a major flow of electrons takes place) is applied to different points on the protruded tongue and the amount of current which is necessary to produce an acid taste is recorded.

electrogustometry
1. An assessment of the integrity of the sense of taste by using graded electrical stimuli that is applied to the lingual mucosa or tongue.
2. A measurement which tests the degree of the sense of taste by applying a direct electrical current to various points on the tongue.

An anode or electrode to which a major flow of electrons takes place and that is applied to different points on the protruded tongue and the electric current necessary to produce an acid taste is measured and recorded.

electrohemodynamics, EHD
A technique for noninvasively measuring the mechanical properties and hemodynamic characteristics of the vascular system, including arterial blood pressure, electric impedance, blood flow, and resistance to blood flow.
electrohemostasis
1. The stopping of a hemorrhage (bleeding) by applying a high frequency current.
2. Hemostasis or stopping bleeding by means of an electric device, as an electrocautery (burning).
3. The stopping of hemorrhaging by the application of a high-frequency electric current in the reduction or prevention of bleeding during surgical operations while using an electrosurgical knife.
electrohorticulture (s) (noun), electrohorticultures (pl)
The growing of pants by means of human produced lights: "Those who utilize electrohorticuture for agricultural production use electric lights either for supplementing the sunlight or as the only means of providing the illumination necessary for the crops."
electrohydraulic lithotrite
1. A lithotrite in which the the kidney stones are broken up into small pieces in which such action is powered by an electrical pulse generator.
2. An instrument for crushing calculi (lithoclast or lithotripsy) used to treat renal calculi (kidney stones) in which powerful ultrasonic shock waves are focused on the stones, thereby breaking them into small fragments which can be excreted and so avoid the need for surgery.
electrohydraulic, electrohydraulically
A reference to or descriptive terms for the production of mechanical or chemical energy by involving a combination of electric and hydraulic mechanisms.
electrohydraulics
The conversion of electrical energy into mechanical or chemical energy by the controlled discharge of high-voltage electric arcs submerged in water or another fluid.
electrohysterogram
1. A recording of uterine electrical activities.
2. A record of the electrical activity of the uterine muscular contractions.
