| electric conductivity | The capacity to conduct an electric current. Conductivity is the reciprocal of resistance. (12 Dec 1998) |
|---|---|
| electric countershock | An electric shock applied to the heart to terminate a disturbance of its rhythm. (12 Dec 1998) |
| electric dermatome | See: electrodermatome. (05 Mar 2000) |
| electric fish | Fishes which generate an electric discharge. The voltage of the discharge varies from weak to strong in various groups of fish. Electric organ and electroplax are of prime interest in this group. They occur in more than one family. (12 Dec 1998) |
| electric impedance | The opposition to the flow of an alternating current, which is the vector sum of ohmic resistance plus additional resistance, if any, due to induction, to capacity, or to both. (12 Dec 1998) |
| electric injuries | Injuries caused by electric currents. The concept excludes electric burns (burns, electric), but includes accidental electrocution and electric shock. (12 Dec 1998) |
| electric organ | In about 250 species of electric fishes, modified muscle fibres forming disklike multinucleate plates arranged in stacks like batteries in series and embedded in a gelatinous matrix. A large torpedo ray may have half a million plates. Muscles in different parts of the body may be modified, i.e., the trunk and tail in the electric eel, the hyobranchial apparatus in the electric ray, and extrinsic eye muscles in the stargazers. Powerful electric organs emit pulses in brief bursts several times a second. They serve to stun prey and ward off predators. A large torpedo ray can produce of shock of more than 200 volts, capable of stunning a human. (storer et al., general zoology, 6th ed, p672) (12 Dec 1998) |
| electric retinopathy | A macular burn from excessive exposure to sunlight or other intense light (e.g., the flash of a short circuit); characterised subjectively by reduced visual acuity. See: solar maculopathy. Synonym: electric retinopathy, solar retinopathy. Origin: photo-+ retina, + G. Pathos, suffering (05 Mar 2000) |
| electric shock | A sudden violent impression caused by the passage of a current of electricity through any portion of the body. (05 Mar 2000) |
| electric sleep | A condition of convulsions and unconsciousness induced by the passage of an electric current through the brain. (05 Mar 2000) |
| electric stimulation therapy | Application of electric current in treatment without the generation of perceptible heat. It includes electric stimulation of nerves or muscles, passage of current into the body, or use of interrupted current of low intensity to raise the threshold of the skin to pain. (12 Dec 1998) |
| electric wiring | An arrangement of wires distributing electricity. (12 Dec 1998) |
| transcutaneous electric nerve stimulation | Electrical stimulation of nerves and/or muscles to relieve pain; it is used less frequently to produce anaesthesia. The optimal placements of electrodes or "trigger points" may correspond with acupuncture analgesia points. Tens is sometimes referred to as acupuncture-like when using a low frequency stimulus. (12 Dec 1998) |
| auditory field | The space included within the limits of hearing of a definite sound, as of a tuning fork. (05 Mar 2000) |
| bright field illumination | <microscopy> The method of lighting the specimen with a solid cone of rays. Transmitted bright field illumination is performed by a substage condenser. Reflected bright field illumination is performed by a vertical illuminator. Compare: dark field illumination (05 Aug 1998) |
