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. The process of recording the electric activity of the brain by electrodes placed directly on the cerebral cortex, providing a much higher voltage, greater accuracy, and more exact localization than electroencephalography.
It is the strongest hormone regulating the body's electrolyte balance.
Aldosterone acts directly on the kidney to decrease the rate of sodium-ion excretion (with accompanying retention of water), and to increase the rate of potassium-ion excretion.
The primary function of aldosterone is the regulation of electrolyte metabolism, that is, promotion of sodium retention and enhancement of potassium excretion.
2. The stimulation of the growth, development, and maturing of plants by electrical procedures; especially, by static electricity and the fields of forces in the atmosphere.
2. To execute someone by means of the electric chair.
2. A collector or emitter of electric charge or of electric-charge carriers, as in a semiconducting device.
3. A conducting element that performs one or more of the functions of emitting, collecting, or controlling the movements of electrons or ions in an electron tube, or the movements of electrons or holes in a semiconductor device.
4. A medium for conducting an electrical current from the body to physiological monitoring equipment.
5. A terminal or surface at which electricity passes from one material or medium to another, as at the electrodes of a battery or electrolytic capacitor.
6. One of the terminals of metal, salts, or electrolytes through which electricity is applied to, or taken from, the body or an electric device or instrument.
7. An electronically conductive structure that provides for an electrochemical reaction through the change of oxidation state of a substance.
It may contain or support the reactant or act as the site for the reaction. The anode and cathode of an electric cell are electrodes.
