| SGE | secondary generalized epilepsy |

| sHPT | secondary hyperparathyroidism |
| point tenderness | <clinical sign> A finding on physical examination that can indicate a localised inflammatory process due to injury or disease. Point tenderness will be discovered over fracture sites (in bone injury). (27 Sep 1997) |
|---|---|
| critical point | A point at which two phases become identical; thus, at a given critical temperature and critical pressure, the liquid and gaseous state of a particular substance can no longer be differentiated. (05 Mar 2000) |
| critical point drying | <procedure> A method for preparing specimens for the scanning electron microscope that avoids the problems of shrinkage caused by normal drying procedures. Water in the specimen is replaced by an intermediate fluid, for example liquid carbon dioxide, avoiding setting up a liquid/gas interface and then the second fluid is allowed to vaporise by raising the temperature above the critical point, the temperature at which the liquid state no longer occurs. (18 Nov 1997) |
| posterior focal point | The point of a compound optical system where parallel rays entering the system are focused. (05 Mar 2000) |
| power point | In dentistry, the vertical dimension at which the greatest masticatory force may be registered. (05 Mar 2000) |
| preauricular point | A point of the posterior root of the zygomatic arch lying immediately in front of the upper end of the tragus. (05 Mar 2000) |
| Halle's point | <anatomy> A point at the intersection of a horizontal line touching the anterior superior spine of the ilium and a perpendicular line drawn from the spine of the pubis; here the ureter can be most readily palpated. (05 Mar 2000) |
| pressure point | A cutaneous locus having pressure-sensitive elements which when compressed, pressure is appreciated. (05 Mar 2000) |
| 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) |
| 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) |
