| short-circuit | <physics> A circuit formed or closed by a conductor of relatively low resistance because shorter or of relatively great conductivity. <physics> To join, as the electrodes of a battery or dynamo or any two points of a circuit, by a conductor of low resistance. Origin: Short-circuited; Short-circuiting. Source: Websters Dictionary (01 Mar 1998) |

| anaesthesia, closed-circuit | Inhalation anaesthesia where the gases exhaled by the patient are rebreathed as some carbon dioxide is simultaneously removed and anaesthetic gas and oxygen are added so that no anaesthetic escapes into the room. Closed-circuit anaesthesia is used especially with explosive anaesthetics to prevent fires where electrical sparking from instruments is possible. (12 Dec 1998) |
| anaesthetic circuit | Equipment used during inhalation anaesthesia to regulate concentrations of inhaled gases; includes a reservoir bag and usually directional valves, breathing tubes, and a carbon dioxide absorber. (05 Mar 2000) |
| break-circuit | <physics> A key or other device for breaking an electrical circuit. Source: Websters Dictionary (01 Mar 1998) |
| Papez circuit | A long circuitous conduction chain in the mammalian forebrain, leading from the hippocampus by way of the fornix to the mammillary body and thence returning to the hippocampus by way of, sequentially, the anterior thalamic nuclei, cingulate gyrus, and parahippocampal gyrus. (05 Mar 2000) |
| reverberating circuit | A theory of periodic conduction through the cerebral cortex of trains of impulses traveling in circuit's of neurons. (05 Mar 2000) |
| circuit | The path or course of flow of cases or electric or other currents. Origin: L. Circuitus, a going round, fr. Circum, around, + eo, pp. Itus, to go (05 Mar 2000) |
| closed circuit method | A method for measuring oxygen consumption in which the subject rebreathes an initial quantity of oxygen through a carbon dioxide absorber and the decrease in the volume of oxygen being rebreathed is noted. (05 Mar 2000) |
| open circuit method | A method for measuring oxygen consumption and carbon dioxide production by collecting the expired gas over a known period of time and measuring its volume and composition. (05 Mar 2000) |
| local circuit theory | <physiology> A generally accepted model for neuronal conduction, by which depolarisation of a small region of a neuronal plasma membrane produces transmembrane currents in the neighbouring regions, tending to depolarise them. As the sodium channels are voltage gated, the depolarisation causes further channels to open, thus propagating the action potential. (18 Nov 1997) |
| 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) |
