|---|---|---|---|
| 설명 | 조직이나 세포 혹은 기관의 크기가 원래의 크기에 비하여 줄어드는 것을 일컫는 말. 처음부터 크기가 작은 무형성/형성저하증(aplasia/hypoplasia)와 구별된다. |

| 영문 | optic nerve | 한글 | 시각신경 |
|---|---|---|---|
| 설명 | 시각을 인지하는 신경. 이 신경은 단지 감각신경으로서만 작용한다. 따라서 어떤 사물을 따라 눈을 움직일 수 있는 것은 이 시각신경과는 무관하다(이것은 눈돌림신경(oculomotor nerve)에 의해 가능하다). 또한 시각신경은 고위중추신경계인 뇌에서 직접 분지하므로 손상시 재생은 불가능하며, 이에 대한 치료법은 없다. |

| 영문 | optic disk | 한글 | 시신경유두 |
|---|---|---|---|
| 설명 | 망막의 구조를 직상검안경(망막을 보기 위해 고안된 검사기구)으로 보면 다음과 같다. 망막에 혈액을 공급하는 망막동맥(retinal artery)과, 다시 혈액을 회수하는 망막정맥(retinal vein)은 다같이 시각신경(optic nerve)과 함께 시각신경구멍(optic foramen)을 통해 망막까지 이르게 된다. 즉, 이들 망막 동, 정맥은 시각신경속에 끼워진 채 망막까지 이르게 된다. 따라서 이들 망막 동, 정맥 주위에 존재하는 시각신경유두는 바로 시각신경의 일부분을 말한다. 빛의 자극을 이해할 수 있는 신호체계로 바꾸는 시각세포는 받아들인 자극을 시각신경에서 분지한 수많은 신경절세포(ganglion cell: 신경전달을 모아서 보다 큰 전달단위로 전해주는 역할을 하며, 망막내에 위치한다)로 전달하게 되고, 이들 신경절세포는 다시 이런 자극들을 모아 시각신경유두로 보내게 되며, 시각신경유두에서부터 신경전달은 뇌까지 진행한다.  |

| optic atrophy | Atrophy of the optic disk resulting from degeneration of the nerve fibres of the optic nerve and optic tract. (12 Dec 1998) |
|---|---|
| optic atrophy, hereditary | An inherited disorder in which optic atrophy is associated with muscle weakness, peroneal muscular atrophy and, in some patients, lancinating pains. In these patients the peripheral sensory neurons are probably affected. (12 Dec 1998) |
| Leber's hereditary optic atrophy | Hereditary degeneration of the optic nerve and papillomacular bundle with resulting rapid loss of central vision, progressive for several weeks, then usually stationary with permanent central scotoma; age of onset is variable, most often in the third decade; more males than females are affected and transmission is cytoplasmic and strictly on the female side. Mutation on the mitochondrial chromosome involved, which presumably interacts with an X-linked mutant. This mechanism may explain the bizarre sex ratio, which differs significantly from one country to another. (05 Mar 2000) |
| autosomal dominant | <genetics> Requires only one affected parent have the trait to pass it to offspring. (02 Jan 1998) |
| genes, dominant | Genes that are reflected in the phenotype both in the homozygous and the heterozygous state. (12 Dec 1998) |
| permanent dominant idea | An exaggerated notion, belief, or delusion that persists, despite evidence to the contrary, and controls the mind, the obstinate conviction of a psychotic person regarding the correctness of his delusion. Synonym: idee fixe, overvalued idea, permanent dominant idea. (05 Mar 2000) |
| dominant | <genetics> A gene is said to be dominant if it expresses its phenotype even in the presence of a recessive gene. (09 Oct 1997) |
| dominant character | An inherited character determined by one kind of allele. See: phenotype. (05 Mar 2000) |
| dominant eye | The eye that is customarily used for monocular tasks. Synonym: master eye. (05 Mar 2000) |
| dominant frequency | The frequency occurring most often in an electroencephalogram. (05 Mar 2000) |
| dominant gene | dominance of traits |
| dominant hemisphere | That cerebral hemisphere containing the representation of speech and controlling the arm and leg used preferentially in skilled movements; usually the left hemisphere. (05 Mar 2000) |
| dominant idea | An idea that governs all one's actions and thoughts. (05 Mar 2000) |
| dominant inheritance | dominance of traits |
| dominant lethal trait | Trait, expressed in the phenotype if present in the genotype, that precludes having descendants. All such cases are necessarily sporadic and must represent new mutations as the usual methods of classical genetics provide no means of demonstrating any genetic component whatsoever, except for tenuous arguments such as advanced paternal age. Molecular biology may help although the methods may be tedious; if there is an epistatic gene that may mask the trait, the logic is more tractable, though complex. (05 Mar 2000) |
