| 설명 | 안구의 각막과 수정체 사이에 있는 둥근 모양의 얇은 막. 막의 중앙에 동공이 있으며, 홍채의 신축으로 동공이 축소되거나 확대되어 안구에 들어오는 빛의 양을 조절한다. 인종에 따라 색소가 다른다. 눈동자의 주위에 있는 고리 모양의 막, 검은 눈동자의 본체는 각막을 통해 흑색으로 보이는 홍채이다. 중앙에 원형의 동공이 있고, 이 곳을 통하여 전안방과 후안방이 이어진다. 홍채가 이완하거나 수축함에 따라 동공의 크기가 변하고 따라서 망막에 달하는 광선의 양이 조절된다. 즉, 홍채는 카메라의 조리개에 해당한다. 홍채의 이완과 수축은 그 속에 있는 동공산대근 및 동공조임근에 의하여 이루어진다. 홍채의 외주연은 섬모체연이라고 하며, 모양체에 연결되어 있다. 또 내측연, 즉 동공의 외주연은 동공연이라고 한다. 홍채의 조직은 색소세포가 풍부한 층으로 되어 있는데, 그 색소의 빛깔이나 혈관의 다소에 의하여 홍채의 빛깔이 달라 보인다.  |

| mesodermal | <biology> Pertaining to, or derived from, the mesoderm; as, mesodermal tissues. Source: Websters Dictionary (01 Mar 1998) |
| mesodermal factor | A protein that can induce the formation of kidney and muscle primordia in embryos. (05 Mar 2000) |
| mixed mesodermal tumour | A sarcoma of the body of the uterus arising in older women, composed of more than one mesenchymal tissue, especially including striated muscle cells. Synonym: malignant mixed mullerian tumour. (05 Mar 2000) |
| mixed tumour, mesodermal | A sarcoma of the body of the uterus arising in older women, composed of more than one mesenchymal tissue, especially including striated muscle cells. It is associated with previous pelvic radiation exposure in 20% of patients. (12 Dec 1998) |
| gonadal dysgenesis | <embryology, genetics> A rare genetic disorder in women that is characterised by the absence of an X chromosome. This disorder inhibits normal sexual development and causes infertility. Features include webbing of the neck, short stature, retarded development of secondary sex characteristics, absence of menses, coarctation of the aorta, low hairline, eye abnormalities (drooping eyelids) and skeletal deformities. Treatment include oestrogen supplementation at puberty. Growth hormone replacement may be necessary in some cases. Cardiac surgery may be necessary to correct coarctation of the aorta. Incidence: 1 in 3,000 births. (10 Oct 1997) |
| gonadal dysgenesis, 46,xy | A syndrome characterised by "streak gonads" in a phenotypic female with a 46,xy karyotype. It is due to a mutation which inhibits the function of the y-borne determinant that would normally cause the indifferent embryonic gonad to differentiate into a testis. The streak gonad is incapable of ovulation or oestrogen secretion. The syndrome is sometimes called "pure gonadal dysgenesis," but this designation may also refer to the presence of streak gonads with a 46,xx karyotype. (12 Dec 1998) |
| gonadal dysgenesis, mixed | A syndrome of gonadal dysgenesis in which there is a testis on one side and a "streak gonad" on the other. The phenotype is generally male, but may be female since the individual is a mosaic. Various karyotypes have been identified, including 45,xo/47,xyy; 45,xo/46,xy; and 45,xo/46,xyo. (12 Dec 1998) |
| seminiferous tubule dysgenesis | A disorder in which the seminiferous tubules exhibit an abnormal cytoarchitecture and extensive hyalinization; the testes are small, and few spermatozoa are formed; the body habitus may be eunuchoid, and gynaecomastia may be present; urinary gonadotropin output is usually high, and the incidence of mental deficiency and illness increased; sex chromatin may be male or female, and androgen secretion ranges from subnormal to normal. It is a constant feature of (and is often used synonymously with) Klinefelter's syndrome. Synonym: germinal aplasia. (05 Mar 2000) |
| hybrid dysgenesis | The inability of certain strains of the fruit fly Drosophila melanogaster to interbreed with each other because they produce offspring that are all sterile or offspring which have a high number of harmful mutations. (09 Oct 1997) |
| dysgenesis | Defective development. (18 Nov 1997) |
| testicular dysgenesis | A congenital derangement of seminiferous tubular structure and function, resulting in male infertility; the defect in spermatogenesis may be incomplete, as in maturational arrest or premature sloughing, or spermatogenesis may be completely absent, as in the Sertoli-cell-only syndrome. (05 Mar 2000) |
| angle of iris | The acute angle between the iris and the cornea at the periphery of the anterior chamber of the eye. Synonym: angulus iridocornealis, angle of iris, angulus iridis, filtration angle. (05 Mar 2000) |
| anteflexion of iris | Rarely used term for an iris that is in part, folded forward after a severe iridodialysis so that the pigmented layer faces forward. (05 Mar 2000) |
| anterior surface of iris | The anterior surface of the iris of the eye. Synonym: facies anterior iridis. (05 Mar 2000) |
