| electronegativity | The likelihood that an atom or molecule will attract electrons, the strength of the attraction. The tendency of an atom or molecule to become negatively charged. (09 Oct 1997) |

| electroneurography | Diagnosis of disease states by recording the spontaneous electrical activity of tissues or organs or by the response to stimulation of electrically excitable tissue. (12 Dec 1998) |
| electroneurolysis | Destruction of nerve tissue by electricity. (05 Mar 2000) |
| electroneuromyography | A method of measuring changes in a peripheral nerve by combining electromyography of a muscle with electrical stimulation of the nerve trunk carrying fibres to and from the muscle. (05 Mar 2000) |
| electronic | 1. Pertaining to electrons. 2. Denoting devices or systems utilizing the flow of electrons in a vacuum, gas, or saemiconductor. (05 Mar 2000) |
| electronic cell counter | <apparatus, haematology> An automatic blood cell counter in which cells passing through an aperture alter resistance and are counted as voltage pulses, or in which cells passing through a flow cell deflect light. Some types of counter are capable of multiple simultaneous measurements on each blood sample; e.g., leukocyte count, red cell count, haemoglobin, haematocrit, and red cell indices. (21 Jun 2000) |
| electronic number | <chemistry> The number of electrons in the outermost orbit (valence shell) of an element. (05 Mar 2000) |
| electronic pacemaker | An electric device that can substitute for the normal cardiac pacemaker, controlling the heart's rhythm by artificial electric discharges. Synonym: electronic pacemaker. (05 Mar 2000) |
| electronic pacemaker load | The impedance to the output, the standard load being 500 ohms resistance ± 1%. (05 Mar 2000) |
| electronic potential | <chemistry, physiology> The measure (in volts) of electron pressure. A measure of the difference in electron concentrations between two compartments, such as either side of a cell membrane. (09 Oct 1997) |
| electrons | Stable elementary particles having the smallest known negative charge, present in all elements; also called negatrons. Positively charged electrons are called positrons. The numbers, energies and arrangement of electrons around atomic nuclei determine the chemical identities of elements. Beams of electrons are called cathode rays or beta rays, the latter being a high-energy biproduct of nuclear decay. (12 Dec 1998) |
| electronystagmogram | <investigation> A test which involves the graphic recording of eye movements usually used to confirm the presence of nystagmus. This test is useful in the evaluation of dizziness (vertigo) and can help determine if there is damage to the vestibular portion of the acoustic nerve. It may be performed in situations of suspected acoustic neuroma, benign positional vertigo, labyrinthitis and Meniere's disease. (27 Sep 1997) |
| electronystagmography | <investigation> A neurologic test which measures fine motor movements of the eye muscles, used to confirm the presence of nystagmus. Small metal electrodes are placed above, below and to the sides of each eye. A graphical recording of eye movements is then generated. This test is used to evaluate dizziness, vertigo and the function of the acoustic nerve. Conditions such as labyrinthitis, Meniere's disease and acoustic neuroma may have an ENG study performed as part of the evaluation. (27 Sep 1997) |
| electroparacentesis | <procedure> Removal of fluid, as from the eye, with an electrically activated instrument. (05 Mar 2000) |
| electropathology | The study of pathologic conditions in their relation to electrical reactions. (05 Mar 2000) |
| electroconvulsive treatment |
Electroconvulsive therapy, also known as electroshock or ECT, is a controversial type of psychiatric shock therapy involving the induction of an artificial seizure in a patient by passing electricity through the brain. Researchers remain uncertain as to exactly how ECT affects improvements in mental state, though patients with a variety of conditions have shown improvement after the procedure. ...

| electromotive force |
Electromotive force (emf) is a measure of the strength of a source of electrical energy. The unit of emf is the volt (energy per unit electric charge) and so the term 'force' is misleading. Thus, the expansion of the acronym is considered obsolete or at best, an embarrassing historical artifact. (The term is attributed to Alessandro Volta.). ...

| electromagnetic |
Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, composed of the electric field and the magnetic field. The electric field can be produced by stationary electric charges, and gives rise to the electric force, which causes static electricity and drives the flow of electric current in electrical conductors. ...

| electron theory |
The electron is a subatomic particle. In an atom the electrons surround the nucleus of protons and neutrons in an electron configuration. The word electron was coined in 1894 and is derived from the term electric, whose ultimate origin is the Greek word 'ηλεκτρον, meaning amber. ...
