| 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) |
| elementary body |
1. old term for platelet. 2. an inclusion body. 3. the infectious extracellular form of Chlamydia, consisting of electron-dense nuclear material and a few ribosomes surrounded by a rigid trilaminar wall. Elementary bodies are taken up into cells where they reorganize into reticulate bodies (qv); following reproduction, chlamydiae are released from the cell as elementary bodies.

| electron transport chain |
the series of electron carriers in the inner mitochondrial membrane that pass electrons from reduced coenzymes (NADH, FADH 2 ) to molecular oxygen via sequential redox reactions coupled to vectorial transduction of protons across the membrane. The chain is the final common pathway of biological oxidation, using O 2 for fuel combustion; the energy produced is utilized for ATP synthesis, ion translocation, and protein synthesis. See illustration. See also oxidative phosphorylation. ...

| electric |
Electricity is a property of certain subatomic particles (e.g. electrons / protons) which couples to electromagnetic fields and causes attractive and repulsive forces between them. Electricity gives rise to one of the four fundamental forces of nature, and is a conserved property of matter that can be quantified. In this sense, the phrase "quantity of electricity" is used interchangeably with the phrases "charge of electricity" and "quantity of charge. ...

| electric shock |
An electric shock may occur upon contact with electricity. An electric shock can be lethal, but the level of voltage is not a direct guide to lethality, despite the popularity of such a measure. Physiological effects are determined by voltage, current and duration. A high voltage and a high current together are lethal, but so are a lower voltage and current of extended duration. ...
