a theory of the evolution of color vision: first, light stimulates a substance in the visual cells, producing a sensation of white light; next, molecular changes from the first reaction produce two reactive products, one for each end of the spectrum, for blue and yellow; finally, the reactive product from the yellow becomes two products for red and green. Dichromasies and anomalous trichromasies are considered to be incomplete recapitulations of the evolutionary development.

a diagrammatic representation of the routes of cardiac conduction as determined by electrocardiographic recording, used in diagnosing arrhythmias. Vectors describing the origins and paths of individual normal or ectopic impulses as well as points of blocks to conduction are drawn across a series of horizontal lines representing the atria, atrioventricular node, ventricles, and sometimes additional regions of the conduction system. See illustration. Called also laddergram. Click here to view image■Ladder diagrams. (A), Sinus rhythm; (B), atrioventricular nodal reentrant tachycardia; AVN, atrioventricular node; BB, bundle branch.

The result of ladder programming used to control a PLC. The ladder language is modeled after relay wiring schematics. The fundamental theories behind ladder are consistent among all manufacturers. However, each PLC manufacturer generally has a proprietary ladder software package.
