| 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) |
| action current | An electrical current induced in muscle fibres when they are effectively stimulated; normally it is followed by contraction. (05 Mar 2000) |
| alternating current | Electrical current which alternates direction periodically. (For instance, household electric current is AC alternating at 60 oscillations/sec (60 Hertz) in the United States, and 50 Hertz in many other countries.) Acronym: AC (09 Oct 1997) |
| anodal current | A current produced in tissues under the anode when the circuit is closed. (05 Mar 2000) |
| ascending current | The direction of current flow in a nerve when the anode is placed peripheral to the cathode, in contrast to descending current; the convention used is that current flows from positive to negative. Synonym: centripetal current. (05 Mar 2000) |
| axial current | The central rapidly moving portion of the bloodstream in an artery. (05 Mar 2000) |
| bootstrap current | <radiobiology> Currents driven in toroidal devices by neo-classical diffusion. They may amount to a substantial fraction of the net current in a tokamak reactor, thus lengthening the pulse time or decreasing the power needed for current drive. (09 Oct 1997) |
| calcium current | Inflow of calcium ions through specific calcium channels. Critically important in release of transmitter substance from presynaptic terminals. (18 Nov 1997) |
| galvanic current | See: direct current, galvanism. (05 Mar 2000) |
| radio frequency current drive | <radiobiology> Plasma waves in the radio-frequency range can be used to push plasma particles in such a way that current forms in the plasma, this is a method of non-inductive current drive which would allow for steady-state fusion reactors to operate. (09 Oct 1997) |
| gating current | <physiology> Small currents in the membrane just prior to the increase in ionic permeability, due to the movement of charged particles within the membrane. So called because they open the gates for current flow through ion channels. (20 Mar 1998) |
| M current | <physiology> Flow of potassium ions through M channels. (26 Mar 1998) |
| centrifugal current | The direction of current flow in a nerve when the cathode is placed peripheral to the anode, in contrast to ascending current. Synonym: centrifugal current. (05 Mar 2000) |
