| 설명 | 혈관이나 혹은 내강을 이루는 관이 막히는 경우를 폐색이라고 한다. 이중 혈관에 있어서 폐색이 발생하면, 그 혈관에 의해 혈액을 공급받는 이하부위에서 허혈(혈액이 공급되지 않아 그 조직이 죽기 직전의 단계. 이 부위는 대사가 감소하고, 온도가 떨어지며, 오래 방치해두면 죽게 된다)이나, 혹은 괴사(세포가 죽는 단계. 심장에서는 경색이라고 부름)에 빠지게 된다. 이때 폐색을 일으키는 경우는 다음 2가지 경우가 있다. 여기서 혈전증이라는 말은 피가 모여서 이른바 “피떡”을 형성한 상태를 말한다. 쉽게 말하면, 피부에서 상처가 생기면, 상처주위로 피떡이 생겨 더이상 피가 흐르지 않도록 하는데, 이런 현상이 피가 굳어서는 안되는 혈관내에서 발생하여, 혈관을 막는 경우를 말한다. 이에 비해 색전증이라는 말은 다른 곳에서 생긴 “혈전”이나 혹은 “지방” “공기”등이 혈액내로 들어와 혈액을 떠돌아 다니다가 크기가 작은 혈관을 막아 폐색을 일으키는 경우를 말한다. |

| spherical form of occlusion | An arrangement of teeth which places their occlusal surfaces on the surface of an imaginary sphere (usually 8 inches in diameter) with its centre above the level of the teeth. See: Monson curve. (05 Mar 2000) |

| aberration, spherical | <optics> A lens defect whereby image forming rays of one colour, passing through the outer zones of a lens come to focus at a different distance from the lens than do those of more central rays. With a simple spherical (or plano-spherical) lens the outer rays always meet the axis closer to the lens than do more central rays and the lens is uncorrected or undercorrected. When the reverse is true the lens has been overcorrected. (05 Aug 1998) |

| spherical | Pertaining to, or shaped like, a sphere. (05 Mar 2000) |
| spherical aberration | <microscopy> A lens defect in which image forming rays passing through the outer zones of the lens focus at a distance from the principal plane, different from that of the rays passing through the centre of the lens. The aberration caused by (near-paraxial) monochromatic light rays or electron beams passing through different radii of a lens not coming to the same focus. (05 Aug 1998) |
| spherical amalgam | An alloy for dental amalgam composed of spherical particles instead of filings. (05 Mar 2000) |
| spherical lens | A lens in which all refracting surfaces are spherical. (05 Mar 2000) |
| spherical nucleus | Spinal nucleus of accessory nerve, a slender column of motor neurons extending longitudinally through the central part of the ventral horn of the upper five segments of the spinal cord, giving origin to the spinal part of the accessory nerve. Synonym: nucleus spinalis nervi accessorii, globosus nucleus. (05 Mar 2000) |
| spherical recess | A rounded depression on the inner wall of the vestibule of the labyrinth, lodging the sacculus. Synonym: recessus sphericus, fovea hemispherica, fovea spherica. (05 Mar 2000) |
| a-form DNA | <molecular biology> One of several forms that can be assumed by a double helix. A-DNA is stable in dehydrated conditions. This form is less common than the dominant form found under physiological conditions -- beta-DNA. This form is also assumed by DNA-RNA hybrid helices and by regions of double-stranded RNA. It is a right-handed helix and is a more compact form than beta-DNA. (09 Oct 1997) |
| boat form | The less stable of two conformations assumed by 6-membered cyclic sugars (pyranoses) or cyclohexane derivatives, as opposed to chair form. See: Haworth conformational formulas of cyclic sugars. (05 Mar 2000) |
| cavity preparation form | The configuration or shape of a cavity preparation. (05 Mar 2000) |
| replicative form | An intermediate stage in the replication of either DNA or RNA viral genomes that is usually double stranded, the altered, double-stranded form to which single-stranded coliphage DNA is converted after infection of a susceptible bacterium, formation of the complementary ("minus") strand being mediated by enzymes that were present in the bacterium before entrance of the viral ("plus") strand. (05 Mar 2000) |
| resistance form | The shape given to a cavity preparation that enables the dental restoration to withstand masticatory forces. (05 Mar 2000) |
| retention form | The shape of a cavity preparation that prevents displacement of the dental restoration by lateral or tipping forces as well as masticatory forces. (05 Mar 2000) |
| chair form | The more stable of two conformations assumed by 6-membered cyclic sugars (e.g., the pyranoses) or cyclohexane derivatives, as opposed to boat form. See: Haworth conformational formulas of cyclic sugars. (05 Mar 2000) |
| wave form | The form of a pulse; e.g., an arterial pressure or displacement wave; or of the pacemaker pulse as demonstrated on the oscilloscope under a specified load. Synonym: waveshape. (05 Mar 2000) |
