| mesonephric adenocarcinoma | A rare tumour of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognised: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumour (called also endodermal sinus tumour and yolk sac tumour), occurring chiefly in children. The latter variety may also arise in the testis. (12 Dec 1998) |
| mesonephric duct | A duct in the embryo draining the mesonephric tubules; in the male it becomes the ductus deferens; in the female it becomes vestigial. See: longitudinal duct of epoophoron. Synonym: ductus mesonephricus, wolffian duct. (05 Mar 2000) |
| mesonephric fold | A ridge which, in early human embryos, comprises the entire urogenital ridge; however, later in development a more medial genital ridge, the potential gonad, is demarcated from it. See: urogenital ridge. Synonym: mesonephric fold. (05 Mar 2000) |
| mesonephric rest | Remnants of the wolffian duct in the female genital tract that give rise to cysts; e.g., Gartner's cyst. Synonym: mesonephric rest. (05 Mar 2000) |
| mesonephric ridge | A ridge which, in early human embryos, comprises the entire urogenital ridge; however, later in development a more medial genital ridge, the potential gonad, is demarcated from it. See: urogenital ridge. Synonym: mesonephric fold. (05 Mar 2000) |

| aerenchymous tissue | A type of plant tissue in which cells are unusually large, resulting in large air spaces in the plant organ, such tissues are often referred to as spongy and usually provide increased buoyancy. (09 Oct 1997) |
| areolar tissue | Loose, irregularly arranged connective tissue that consists of collagenous and elastic fibres, a protein polysaccharide ground substance, and connective tissue cells (fibroblasts, macrophages, mast cells, and sometimes fat cells, plasma cells, leukocytes, and pigment cells). (05 Mar 2000) |
| bone tissue | A connective tissue, the matrix of which consists of collagen fibres and ground substance and in which are deposited calcium salts (phosphate, carbonate, and some fluoride) in the form of an apatite. Synonym: bone tissue. (05 Mar 2000) |
| border tissue movements | The action of the muscles and other tissues adjacent to the borders of a denture. (05 Mar 2000) |
| brain tissue transplantation | Transference of brain tissue, either from a foetus or from a born individual, between individuals of the same species or between individuals of different species. (12 Dec 1998) |
