| Ritter's law | A nerve is stimulated at both the opening and the closing of an electrical current. See: law of polar excitation. (05 Mar 2000) |

| ritter disease | This is the scalded skin syndrome, a potentially serious side effect of infection with the staph (staphylococcus) bacteria that produces a specific protein which loosens the cement holding the various layers of the skin together. This allows blister formation and sloughing of the top layer of skin. If it occurs over large body regions it can be deadly (just like a large surface area of the body having been burned). It is necessary to treat scalded skin syndrome with intravenous antibiotics and to protect the skin from allowing dehydration to occur if large areas peel off. The disease occurs predominantly in children under 5 years of age. It is known formally as staphyloccoccal scalded skin syndrome. (12 Dec 1998) |

| Ritter, Johann | <person> German physicist, 1776-1810. See: Ritter's law, Ritter's opening tetanus, Ritter-Rollet phenomenon. (05 Mar 2000) |
| Ritter-Rollet phenomenon | On equal electrical stimulation of motor nerve trunks, the flexor and abductor muscle groups react more readily than the extensors and adductors. (05 Mar 2000) |
| Ritter's opening tetanus | The tetanic contraction that occasionally occurs when a strong current, passing through a long stretch of nerve, is suddenly interrupted. (05 Mar 2000) |
| Hardy-Rand-Ritter test | A test for colour vision deficiency using pseudoisochromatic cards. These excellent cards have not been reprinted by the American Optical Co. Since the plates were accidentally destroyed in 1965. (05 Mar 2000) |

| Jaeger, Eduard Ritter von Jaxthal | <person> Austrian ophthalmologist, 1818-1884. See: Jaeger's test types. (05 Mar 2000) |
| Abbe's law of limiting resolution | <physics> For a periodic structure of units separated by distance d and obliquely illuminated by the unrefracted ray and one of the two diffracted rays (extremely oblique illumination). Abbe applied the law of diffraction: d = 0.5 lambda /NA, where: lambda = wavelength of the monochromic light or shortest of mixed wavelengths NA = the limiting numerical aperture (NA) of objective or condenser. (05 Aug 1998) |
| all or none law | Consistently total response to any effective stimulus. Synonym: all or none law. (05 Mar 2000) |
| American Law Institute formulation | Used in certain jurisdictions to determine criminal responsibility in legal proceedings. See: criminal insanity. (05 Mar 2000) |
| American Law Institute rule | A test of criminal responsibility (1962): "a person is not responsible for criminal conduct if at the time of such conduct as a result of mental disease or defect he lacks substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of law." (05 Mar 2000) |
| Ampere's law | <physics> General equation in electromagnetism relating the magnetic field and the currents generating it. The various forms of the equation can be found in an introductory electromagnetism text. (09 Oct 1997) |
| Angstrom's law | A substance absorbs light of the same wavelength as it emits when luminous. (05 Mar 2000) |
| Arndt's law | An obsolete law stating that weak stimuli excite physiologic activity, moderately strong ones favour it, strong ones retard it, and very strong ones arrest it. (05 Mar 2000) |
| Arrhenius law | The theory of electrolytic dissociation (1887) that became the basis of our modern understanding of electrolytes: in an electrically conductive solution (e.g., acid, base, or salt), free ions are present before electrolysis, and the proportion of molecules dissociated into ions can be calculated from measurements of electrical conductivity as well as of osmotic pressure. Synonym: Arrhenius law. (05 Mar 2000) |
