| generator potential | Local depolarisation of the membrane potential at the end of a sensory neurone in graded response to the strength of a stimulus applied to the associated receptor organ, e.g., a pacinian corpuscle; if the generator potential becomes large enough (because the stimulus is at least of threshold strength), it causes excitation at the nearest node of Ranvier and a propagated action potential.

| motor-generator | <physics> Device used to store energy by accelerating a rotating flywheel to high speeds, energy may be rapidly discharged and converted to shorter-pulse energy. (Used to power TFTR, the electric utility would be a little unhappy if TFTR were to suddenly draw its 30 MW+ of power at random intervals. (09 Oct 1997) |
| X-ray generator | The electronic device that controls production of X-rays in radiography; a key function is rectification of line voltage to produce a smooth direct current voltage to the X-ray tube. (05 Mar 2000) |
| homopolar generator | <physics> A direct-current generator in which the poles presented to the armature are all of the same polarity, so that the voltage generated in the active conductors has the same polarity at all times. A pure direct current is thus produced without commutation. (09 Oct 1997) |
| induction generator | A variable speed multi-pole electric generator. (05 Dec 1998) |
| arrhythmias, atrial | Abnormal heart rhythm due to electrical disturbances in the atria (the upper chambers of the heart) or the AV node relay station , leading to fast heart beats. Examples of atrial arrhythmias includes atrial fibrillation, atrial flutter, and paroxysmal atrial tachycardia (PAT). (12 Dec 1998) |
| atrial | <anatomy> Pertaining to an atrium. (16 Dec 1997) |
| atrial appendage | The small projection from each atrium hanging over like a small ear, more marked on the left, with a small cavity of its own. (05 Mar 2000) |
| atrial arrhythmias | See Arrhythmias, atrial. (12 Dec 1998) |
| atrial arteries | Branches of the right and left coronary arteries distributed to the muscle of the atria. Synonym: arteriae atriales. (05 Mar 2000) |
| atrial auricle | The auricle of atrium. See: left atrium, right atrium. (05 Mar 2000) |
| atrial auricula | A small conical ("ear-shaped") pouch projecting from the upper anterior portion of each atrium of the heart, increasing slightly the atrial volume. See: auricle of left atrium, auricle of right atrium. Synonym: auricula atrialis, atrial auricle, atrial auricula, auricle, auricula, auricular appendage, auricular appendix, skin tag. (05 Mar 2000) |
| atrial bigeminy | Pairing of atrial beats, as when an atrial extrasystole is coupled to each sinus beat. (05 Mar 2000) |
| atrial branches | The atrial branches, the branches of the right coronary artery and the circumflex branch of the left coronary artery distributed to the right and left atrium, respectively. Synonym: rami atriales. (05 Mar 2000) |
| atrial capture beat | The cardiac cycle resulting when, after a period of A-V dissociation, the atria regain control of the ventricles; atrial depolarisation due to retrograde transmission from a ventricular ectopic beat or an electronically paced ventricular impulse. (05 Mar 2000) |
