| chronologic age | The age expressed in years and months; used as a measurement against which to evaluate a child's mental age in computing his Stanford-Binet intelligence quotient. (05 Mar 2000) |
|---|---|
| physical age | The age in terms of structure rather than of function or of passage of time. Synonym: physical age. (05 Mar 2000) |
| physiologic age | Age estimated in terms of function. (05 Mar 2000) |
| developmental age | Age estimated by anatomic development since implantation, the degree of anatomic, physiologic, mental, and emotional maturation. Synonym: foetal age. (05 Mar 2000) |
| old age assistance | Financial assistance for the impoverished elderly through public funding of programs, services, and individual income supplements. (12 Dec 1998) |
| emotional age | A measure of emotional maturity by comparison with average emotional development. (05 Mar 2000) |
| foetal age | Age estimated by anatomic development since implantation, the degree of anatomic, physiologic, mental, and emotional maturation. Synonym: foetal age. (05 Mar 2000) |
| alternating light test | Test to detect a relative afferent defect in one eye by watching pupillary movements. With the patient fixing in the distance, the light is held on each eye for about a second, and quickly moved to the other eye. Assuming no defect of the innervation to the iris sphincter in one eye (which would produce an anisocoria in light), the eye with the weaker light response has a relative afferent pupillary defect. This asymmetry of pupillomotor input can be estimated by holding neutral density filters in front of the better eye until the pupillary responses of the two eyes are balanced. Synonym: swinging light test. (05 Mar 2000) |
| Begg light wire differential force technique | An orthodontic appliance utilizing small gauge labial wires with expansion and contraction loops formed into it and attached to bands fitted to individual teeth; sometimes called Begg light wire differential force technique. (05 Mar 2000) |
| gene rearrangement, b-lymphocyte, light chain | Ordered rearrangement of b-lymphocyte variable gene regions coding for the kappa or lambda light chains, thereby contributing to antibody diversity. It occurs during the second stage of differentiation of the immature b-lymphocyte. (12 Dec 1998) |
| ray, light | <microscopy> The term applied to the lines perpendicular to the wavefronts of waves of light to indicate their direction of travel in an isotropic medium. Note the wave normal and the ray do not coincide in isotropic media. (05 Aug 1998) |
| reflected light | Light directed backward from a mirror. (05 Mar 2000) |
| refracted light | Bent rays of light changed in passage from one transparent medium to another of unequal density. See: refraction. (05 Mar 2000) |
| visible light | <physics> Electromagnetic radiation with wavelengths between 400 nanometres and 750 nanometres. Electromagnetic radiation within this range can be detected by the human eye. Colours depend on the wavelength lengths, a short wavelength (the 400 nm side) looks blue and a long wavelength (the 750 nm side) looks red. (09 Oct 1997) |
| metals, light | Metals with low specific gravity, typically smaller than 5, characterised by a single valence (1, 2, or 3), a simple spectrum, strong electromotive force (positive), and colourless compounds. (12 Dec 1998) |
