| 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) |

| heat-rigor point | <cell biology> The degree of elevated temperature at which coagulation of protoplasm occurs with death of the cell. (05 Mar 2000) |
| x-point | <radiobiology> Place where the poloidal magnetic field vanishes in such a way that two flux surfaces appear to cross, for example where the main plasma joins the divertor or between magnetic islands. Location where magnetic reconnection takes place. See: magnetic reconnection, divertors, O-point. (09 Oct 1997) |
| secondary point of ossification | This is the centre of bone formation appearing later than the punctum ossificationis primarium, usually in epiphysis. Synonym: punctum ossificationis secundarium, secondary point of ossification. (05 Mar 2000) |
| silver point | A solid core cone of silver used in filling root canals in conjunction with a cement or paste. (05 Mar 2000) |
| skin test end-point titration | A quantitative form of intradermal testing for the relative allergenicity of a substance. It is used to determine the amount of an allergen that will be tolerated in immunotherapy. (12 Dec 1998) |
| spinal point | The centre of the root of the anterior nasal spine. Synonym: apophysary point, apophysial point, spinal point. (05 Mar 2000) |
| nasal point | <anatomy> The middle point of the nasofrontal suture. Origin: Nl, fr. L. Nasus nose. Source: Websters Dictionary (01 Mar 1998) |
| near point | That point in conjugate focus with the retina when the eye exerts maximal accommodation. Synonym: punctum proximum. (05 Mar 2000) |
| near point of convergence | The point to which the visual lines are directed when convergence is at its maximum. (05 Mar 2000) |
| near point of the eye | <ophthalmology> The nearest point to the entrance of the pupil of the normal eye at which focus is attained without strain, 10 inches (250 mm) is the generally accepted distance. In very young people and in those with myopia, this distance is less. The near point recedes with age, possibly even causing farsighted condition,. (05 Aug 1998) |
| needle point tracing | A tracing of mandibular movements made by means of a device attached to the opposing arches; its shape resembles that of an arrowhead or a Gothic arch, and when the instrument's marking point is at the apex of the arch, the jaws are considered to be in centric relation. Synonym: arrow point tracing, Gothic arch tracing, Gothic arch, stylus tracing. (05 Mar 2000) |
| neutral point | The point at which a solution is neither acid nor alkaline (pH 7 at 22캜 for aqueous solutions). (05 Mar 2000) |
| nodal point | One of two point's in a compound optical system so related that a ray directed toward the first point will appear to have passed through the second point parallel to its original direction. Synonym: axial point. (05 Mar 2000) |
| subnasal point | The centre of the root of the anterior nasal spine. Synonym: apophysary point, apophysial point, spinal point. (05 Mar 2000) |
