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.
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.
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.
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.
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.
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.
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.
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.
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.
2. A record of the electrical activity of the uterine muscular contractions.
