| principal focus | The real or virtual meeting point of rays passing into a lens parallel to its axis. (05 Mar 2000) |
|---|
| focus, principal | <physics> The point at which a lens focuses an axial object point. Synonymous with focal point. (05 Aug 1998) |
|---|---|
| axis, principal | <microscopy> A line conceived as passing through the centre of a lens to connect the centres of curvature of the lens surfaces. The focal points of a lens lie on the principal axis. (05 Aug 1998) |
| principal | 1. Highest in rank, authority, character, importance, or degree; most considerable or important; chief; main; as, the principal officers of a Government; the principal men of a state; the principal productions of a country; the principal arguments in a case. "Wisdom is the principal thing." (Prov. Iv. 7) 2. Of or pertaining to a prince; princely. Principal axis. See Axis of a curve, under Axis. Principal axes of a quadric, a plane passing through the optical axis of a crystal. Origin: F, from L. Principalis. See Prince. Source: Websters Dictionary (01 Mar 1998) |
| principal artery of thumb | <anatomy, artery> Origin, radial (deep palmar (arterial) arch); distribution, palmar surface and sides of thumb; anastomoses, arteries on dorsum of thumb. Synonym: arteria princeps pollicis, chief artery of thumb, princeps pollicis, principal artery of thumb. (05 Mar 2000) |
| principal investigator | The head researcher responsi for organising and overseeing a clinical trial (09 Oct 1997) |
| principal islets | Separate globular aggregates made up mostly of endocrine pancreatic tissue; present in some fishes and snakes. (05 Mar 2000) |
| principal optic axis | A line passing through the centre of the lens of a refracting system at right angles to its surface. (05 Mar 2000) |
| principal plane | <microscopy> A plane normal to the principal axis of a lens, passing through a principal point. In geometrical construction of ray diagrams through a perfect lens, the single plane that can be considered (disregarding the refraction of the rays at each optical interface) to convert paraxial rays into rays converging onto the rear focal point. For thin symmetrical lenses, there is one principal plane that bisects the lens. For thick or complex lenses, there is a principal plane for the paraxial ray to the left, and another for the paraxial ray to the right, of the lens. (05 Aug 1998) |
| principal point | <microscopy> Mutually conjugate points lying on the lens axis and producing a magnification of one. Object and image distance as well as focal length are calculated (measured) from these points. (05 Aug 1998) |
| principal sensory nucleus of the trigeminus | <anatomy, nerve> The term commonly used to designate the nucleus pontis nervi trigeminalis; located in pons lateral to the motor trigeminal nucleus; receives primary sensory (touch and pressure) input via the trigeminal nerve, projects to ventral posteromedial nucleus of thalamus. Synonym: nucleus sensorius principalis nervi trigemini, nucleus sensorius superior nervi trigemini, principal sensory nucleus of the trigeminus. (05 Mar 2000) |
| principal sensory nucleus of trigeminal nerve | <anatomy, nerve> The term commonly used to designate the nucleus pontis nervi trigeminalis; located in pons lateral to the motor trigeminal nucleus; receives primary sensory (touch and pressure) input via the trigeminal nerve, projects to ventral posteromedial nucleus of thalamus. Synonym: nucleus sensorius principalis nervi trigemini, nucleus sensorius superior nervi trigemini, principal sensory nucleus of the trigeminus. (05 Mar 2000) |
| real focus | The point of meeting of convergent rays. (05 Mar 2000) |
| Ghon's focus | Calcification seen in pulmonary parenchyma (usually mid-lung area) and hilar nodes resulting from earlier, usually childhood, infection with tuberculosis. Synonym: Ghon's complex, Ghon's focus, Ghon's primary lesion. (05 Mar 2000) |
| virtual focus | The point from which divergent rays seem to proceed, or that at which they would meet if prolonged backward. (05 Mar 2000) |
| mink cell focus-inducing viruses | Murine leukaemia viruses discovered in 1976 by hartley, wolford, old, and rowe and so named because the viruses originally isolated had the capacity to transform cell foci in mink cell cultures. Mcf viruses are generated in a multi-step process by recombination with other viral types including akr, friend, moloney, and rauscher. (12 Dec 1998) |
