| celomic metaplasia theory of endometriosis | That endometrial tissue arises directly from the peritoneal mesothelium. (05 Mar 2000) |
| resonance theory of hearing | That the basilar membrane of the cochlea acts as a resonating structure, recording low tones from its apical turns and high tones from its basal turns. Synonym: Helmholtz theory of hearing. (05 Mar 2000) |
| Golgi's theory | <physiology> The scientific theory that there are interconnections between the axons of Golgi cells and the axons of Deiter cells (both are types of neurons) which play important roles in neurotransmission. (09 Oct 1997) |
| membrane expansion theory | That adsorption of anaesthetics into membranes so alters membrane volume and/or configuration that membrane function is affected in such a way as to produce anaesthesia. (05 Mar 2000) |
| chaos theory | A branch of mathematics dealing with events and processes that cannot be predicted precisely on the basis of conventional mathematical theories or laws; some biological processes, e.g., spread of malignant disease, appear to conform to chaos theory, at least sometimes. (05 Mar 2000) |
| chemiosmotic theory | The theory that the synthesis of ATP (an energy source made and used by the organism) within mitochondria and chloroplasts occurs by way of a proton gradient which forms when electrons are passed through their inner membranes. When protons are then passed through the inner membrane in the opposite direction, energy is released and used to make ATP. (09 Oct 1997) |
| Ribbert's theory | <oncology> That a neoplasm may result when a reduction in tension (exerted by adjacent tissues) leads to conditions favourable to uncontrolled growth of cell rests. (05 Mar 2000) |

| personal construct theory | A psychological theory based on dimensions or categories used by a given person in describing or explaining the personality and behaviour of others or of himself.

| Metchnikoff's theory | The phagocytic theory, that the body is protected against infection by the leukocytes and other cells that engulf and destroy the invading microorganisms. (05 Mar 2000) |
| Meyer-Overton theory of narcosis | That narcotic efficiency parallels the coefficient of partition between oil and water, and that lipoids in the cell and on the cell membrane absorb the drug because of this affinity. Synonym: Meyer-Overton theory of narcosis. (05 Mar 2000) |
| miasma theory | An explanation of the origin of epidemics, based on the false notion that they were caused by air of bad quality, e.g., emanating from rotting vegetation in marshes or swamps. (05 Mar 2000) |
| phlogiston theory | <chemistry> The hypothetical principle of fire, or inflammability, regarded by Stahl as a chemical element. This was supposed to be united with combustible (phlogisticated) bodies and to be separated from incombustible (dephlogisticated) bodies, the phenomena of flame and burning being the escape of phlogiston. Soot and sulphur were regarded as nearly pure phlogiston. The essential principle of this theory was, that combustion was a decomposition rather than the union and combination which it has since been shown to be. Origin: NL, fr. Gr. Burnt, set on fire, fr. To set on fire, to burn, fr, a flame, blaze. See Phlox. Source: Websters Dictionary (01 Mar 1998) |
| migration theory | An obsolete theory that sympathetic ophthalmia is caused by a migration of the pathogenic agent through the lymph channels of the optic nerve. (05 Mar 2000) |
