| aplasia | <embryology> A lack of development of an organ or tissue or of the cellular products from an organ or tissue. Compare: hypoplasia. Origin: Gr. Plassein = to form (18 Nov 1997) |
|---|---|
| aplasia cutis congenita | Congenital absence or deficiency of a localised area of skin, with the base of the defect covered by a thin translucent membrane; most often a single area near the vertex of the scalp, but may occur in other areas; underlying structures may also be affected; autosomal inheritance, either dominant or recessive. (05 Mar 2000) |
| radial aplasia-thrombocytopenia syndrome | <syndrome> Aplasia (absence) of the radius (the long bone on the thumb-side of the forearm) and thrombocytopenia (low blood platelets) are key features characterizing this syndrome. There is phocomelia (flipper-limb) with the thumbs always present. The fibula (the smaller bone in the lower leg) is often absent. The risk of bleeding from too few platelets is high in early infancy but lessens with age. The condition is inherited in an autosomal recessive trait with one gene (on a non-sex chromosome) coming from each parent to the child affected with the disease. Alternative names include thrombocytopenia-absent radius syndrome, tar syndrome, and tetraphocomelia-thrombocytopenia syndrome. (12 Dec 1998) |
| germinal aplasia | 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) |
| red-cell aplasia, pure | Suppression of erythropoiesis with little or no abnormality of leukocyte or platelet production. (12 Dec 1998) |
| gonadal aplasia | Congenital absence of essentially all gonadal tissue; the external genitalia and genital ducts are female, but if interstitial cells of Leydig are present, the external genitalia are commonly ambiguous and the genital ducts are female. See: gonadal dysgenesis. Compare: Klinefelter's syndrome, Turner's syndrome. Synonym: gonadal agenesis. (05 Mar 2000) |
| congenital aplasia of thymus | diGeorge syndrome |
| pure red cell aplasia | A transitory arrest of red blood cell production which may occur in the course of a haemolytic anaemia, often preceded by infection, or as a complication of certain drugs; if the arrest persists anaemia may result. See: congenital hypoplastic anaemia. (05 Mar 2000) |
| syndrome, radial aplasia-thrombocytopenia | See syndrome, tar. (12 Dec 1998) |
| thymic aplasia | <disease, immunology> A lack of T lymphocytes, due to failure of the thymus to develop, resulting in very reduced cell-mediated immunity though serum immunoglobulin levels may be normal. See: DiGeorge syndrome. Origin: Gr. Plassein = to form (18 Nov 1997) |
| apparatus suspensorius lentis | A series of delicate meridional fibres arising from the inner surface of the orbiculus ciliaris that run in bundles between, and in a very thin layer over, the ciliary processes; at the inner border of the corona, the fibres diverge into two groups that are attached to the capsule on the anterior and posterior surfaces of the lens close to the equator; the spaces between these two layers of fibres are filled with aqueous humor. Synonym: zonula ciliaris, apparatus suspensorius lentis, suspensory ligament of lens, Zinn's zonule. (05 Mar 2000) |
| axis lentis | A line connecting the anterior and posterior poles of the lens of the eye. Synonym: axis lentis. (05 Mar 2000) |
| capsula lentis | The capsule enclosing the lens of the eye. Synonym: capsula lentis, crystalline capsule, lenticular capsule, phacocyst. (05 Mar 2000) |
| capsula vasculosa lentis | In the embryo, the vascular mesenchymal capsule that invests the lens of the eye; the vessels of the dorsal part of the capsule are branches of the hyaloid artery; those of the ventral part are derived from the anterior ciliary arteries; normally all the vessels are atrophied by the end of the eighth month of intrauterine life. (05 Mar 2000) |
| radii lentis | 9 to 12 faint lines on the anterior and posterior surfaces of the lens that radiate from the poles toward the equator; they mark the lines along which the ends of lens fibres abut. Synonym: lens stars, lens sutures. (05 Mar 2000) |
