|---|---|---|---|
| 설명 | 대뇌의 혈액을 공급하는 동맥. 대뇌의 앞부분의 혈액을 공급하는 앞대뇌동맥(anterior cerebral artery), 중간부위의 혈액을 공급하는 중간대뇌동맥(middle cerebral artery), 뒷부분의 혈액을 공급하는 뒤대뇌동맥(posterior cererbral artery)의 세 가지가 있다. 대뇌는 크게 두 가지 동맥에 의해서 혈액을 공급받는다. 하나는 속목동맥(internal carotid artery)이고 하나는 척추동맥(vertebral artery)이다. 이 동맥들은 좌-우로 두 개씩 쌍을 이루어 뇌에 혈액을 공급한다. 척추동맥은 대동맥에서 나와서 목뼈에 있는 가로돌기구멍을 통해서 머리쪽으로 올라온다. 그리고는 두 개의 좌우 척추가 한 개로 합쳐져서 바닥동맥라는 동맥을 이룬다. 목동맥은 대동맥에서 기시하여 속목동맥과 바깥목동맥으로 나뉜다(나뉘기 이전을 온목동맥이라 한다). 바깥목동맥은 얼굴과 뇌를 제외한 머리의 부위에 혈액을 공급하는 혈관이고, 속목동맥은 뇌에 혈액을 공급한다.   |

| 설명 | 머리부분의 혈액을 공급하는 동맥. 온목동맥는 대동맥에서 직접 나오는 동맥으로, 바깥목동맥와 속목동맥로 나뉜다. 속목동맥은 뇌의 혈액을 공급하는 역할을 하고, 바깥목동맥은 뇌를 제외한 머리부분에 혈액을 공급하는 역할을 한다. |

| apical dominance | <plant biology> Growth inhibiting effect exerted by actively growing apical bud of higher plant shoots, preventing the growth of buds further down the shoot. Thought to be mediated by the basipetal movement of auxin from the apical bud. (18 Nov 1997) |

| genetic dominance | Denoting a pattern of inheritance of an autosomal mendelian trait due to a gene that always manifests itself phenotypically; generally, the phenotype in the homozygote is more severe than in the heterozygote, but details depend on what criterion of phenotyping is used. Dominance of traits, an expression of the apparent physiologic relationship existing between two or more genes that may occupy the same chromosomal locus (alleles). at a specific locus there are three possible combinations of two allelic genes, A and a: two homozygous (AA and aa) and one heterozygous (Aa). If a heterozygous individual presents only the hereditary characteristic determined by gene A, but not a, A is said to be dominant and a recessive; in this case, AA and Aa, although genotypically distinct, should be phenotypically indistinguishable. If AA, Aa, and aa are distinguishable, each from the others, A and a are codominant. (05 Mar 2000) |
| cerebral dominance | The fact that one hemisphere is dominant over the other and will exercise greater influence over certain functions; the left cerebral hemisphere is usually dominant in the control of speech, language and analytical processing, and mathematics, while the right hemisphere (usually nondominant) processes spatial concepts and language as related to certain types of visual images; handedness (right-handed people have left cerebral dominance) is considered a general example of cerebral dominance. (05 Mar 2000) |
| cis dominance | <molecular biology> When a gene or promoter affects only gene activity in the DNA duplex molecule in which it is placed the effect is referred to as cis, as opposed to trans effects when a gene or promoter on one DNA molecule can affect genes on another DNA molecule. Cis dominance is seen only when the appropriate pair or set of genes are all cis to each other. (18 Nov 1997) |
| social dominance | Superiority of relationship and rank of an individual in relation to his associates. (12 Dec 1998) |
| dominance | <genetics> The full phenotypic expression of a gene in both heterozygotes and homozygotes. Origin: L. Dominari = to govern (18 Nov 1997) |
| dominance, cerebral | Dominance of one cerebral hemisphere over the other in cerebral functions. (12 Dec 1998) |
| dominance hierarchy | A social situation in which one organism dominates all below it, the next all below it, and so on down to the organism dominated by all; e.g., the pecking order in apes, seals, barnyard hens, and other species. (05 Mar 2000) |
| dominance measure | The means or method by which dominance is established, including areal coverage and basal area, the total dominance measure is the sum total of the dominance measure values for all species comprising a given stratum. (09 Oct 1997) |
| dominance-subordination | Relationship between individuals when one individual threatens or becomes aggressive and the other individual remains passive or attempts to escape. (12 Dec 1998) |
| dominance threshold number | The number at which 50 percent of the total dominance measure for a given stratum is represented by one or more plant species when ranked in descending order of abundance (i.e., from most to least abundant), when this number is immediately exceeded, the dominant species for the stratum are realised. (09 Oct 1997) |
| incomplete dominance | <genetics> Two alleles of a gene which result in distinctly different phenotypes, but when they are both inherited together in an individual (one from the mother and one from the father - called heterozygosity), the individual ends up with a blend of the two phenotypes. For example: if one allele is for red hair and the other allele is for blue hair, then the individual will have purple hair. (This is in contrast to codominance, where the individual would inherit patches of blue and patches of red hair). (13 Nov 1997) |
| false dominance | Simulation by a recessive trait of the pedigree of dominant inheritance (i.e., recurrence in several generations) by repeated, and often occult, consanguineous matings. Synonym: false dominance. (05 Mar 2000) |
| anastomotic branch of middle meningeal artery to lacrimal artery | <anatomy, artery> A branch of the middle meningeal artery arising in the cranial cavity which runs anteriorly through the superior orbital fissure to anastomose with the lacrimal artery. See: orbital branch of middle meningeal artery. Synonym: ramus anastomoticus arteriae meningeae mediae cum lacrimali. (05 Mar 2000) |
| anterior coronary plexus | The part of the cardiac plexus that accompanies the coronary arteries on the anterior aspect of the heart. (05 Mar 2000) |
