| Starling's law | The energy liberated by the heart when it contracts is a function of the length of its muscle fibres at the end of diastole. Synonym: Starling's law. (05 Mar 2000) |

| starling | 1. <ornithology> Any passerine bird belonging to Sturnus and allied genera. The European starling (Sturnus vulgaris) is dark brown or greenish black, with a metallic gloss, and spotted with yellowish white. It is a sociable bird, and builds about houses, old towers, etc. Called also stare, and starred. The pied starling of India is Sternopastor contra. 2. <zoology> A California fish; the rock trout. 3. A structure of piles driven round the piers of a bridge for protection and support; called also sterling. Rose-coloured starling. Origin: OE. Sterlyng, a dim. Of OE. Stare, AS. Staer; akin to AS. Stearn, G. Star, staar, OHG. Stara, Icel. Starri, stari, Sw. Stare, Dan. Staer, L. Sturnus. Cf. Stare a starling. Source: Websters Dictionary (01 Mar 1998) |

| Starling, Ernest | <person> English physiologist, 1866-1927. See: Starling's curve, Starling's hypothesis, Starling's law, Starling's reflex, Frank-Starling curve. (05 Mar 2000) |
| Starling's curve | A graph in which cardiac output or stroke volume is plotted against mean atrial or ventricular end-diastolic pressure; with increasing venous return and atrial pressure the output proportionately increases until further increments overload the heart and the output falls. Synonym: Frank-Starling curve. (05 Mar 2000) |
| Starling's hypothesis | The principle that net filtration through capillary membranes is proportional to the transmembrane hydrostatic pressure difference minus the transmembrane oncotic pressure difference; although well established, it is called Starling's hypothesis to distinguish it from Starling's law of the heart. (05 Mar 2000) |
| Starling's reflex | Tapping the volar surfaces of the fingers causes flexion of the fingers; analogous to Rossolimo's reflex, for the toes. (05 Mar 2000) |
| Frank-Starling curve | A graph in which cardiac output or stroke volume is plotted against mean atrial or ventricular end-diastolic pressure; with increasing venous return and atrial pressure the output proportionately increases until further increments overload the heart and the output falls. Synonym: Frank-Starling curve. (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) |
| Avogadro's law | Equal volumes of gases contain equal numbers of molecules, the conditions of pressure and temperature being the same. Synonym: Ampere's postulate, Avogadro's hypothesis, Avogadro's postulate. (05 Mar 2000) |
| Starling's law of intestine |
A law stating that a stimulus within the intestine (i.e., the presence of food) initiates a band of constriction on the proximal side and relaxation on the distal side. This results in a peristaltic wave.
