| fimbriae | Thread-like structures present on some bacteria. Pili are shorter thanflagella and are used to adhere bacteria to oneanother during mating and to adhere to animal cells. (09 Oct 1997) |
| fimbriae, bacterial | Thin, hairlike appendages, 1 to 20 microns in length and often occurring in large numbers, present on the cells of gram-negative bacteria, particularly enterobacteriaceae and neisseria. Unlike flagella, they do not possess motility, but being protein (pilin) in nature, they possess antigenic and haemagglutinating properties. They are of medical importance because some fimbriae mediate the attachment of bacteria to cells via adhesins (adhesins, bacterial). Bacterial fimbriae refer to common pili, to be distinguished from the preferred use of "pili", which is confined to sex pili (pili, sex). (12 Dec 1998) |
| fimbriae of uterine tube | The irregularly branched or fringed processes surrounding the ampulla at the abdominal opening of the uterine tube; most of the lining epithelial cells have cilia that beat toward the uterus. Synonym: fimbriae tubae uterinae, laciniae tubae, Richard's fringes. (05 Mar 2000) |
| fimbriae tubae uterinae | The irregularly branched or fringed processes surrounding the ampulla at the abdominal opening of the uterine tube; most of the lining epithelial cells have cilia that beat toward the uterus. Synonym: fimbriae tubae uterinae, laciniae tubae, Richard's fringes. (05 Mar 2000) |
| anovular ovarian follicle | A follicle that does not contain an ovum. (05 Mar 2000) |
| atretic ovarian follicle | A follicle that degenerates before coming to maturity; great numbers of such atretic follicle's occur in the ovary before puberty; in the sexually mature woman, several are formed each month. Synonym: corpus atreticum. (05 Mar 2000) |
| cancer, ovarian | Cancer of the egg sac of females (ovary). In women under age 30, most ovarian growths are benign, fluid-filled sacs called cysts. There are several types of ovarian cancer. Symptoms of ovarian cancer can be vague. Detection of ovarian cancer involves physical examination (including pelvic exam), ultrasound, X-ray tests, CA-125 blood test and biopsy of the ovary. (12 Dec 1998) |
| vesicular ovarian follicle | A follicle in which the oocyte attains its full size and is surrounded by an extracellular glycoprotein layer (zona pellucida) that separates it from a peripheral layer of follicular cells permeated by one or more fluid-filled antra; the theca of the follicle develops into internal and external layers. Synonym: folliculus ovaricus vesiculosus, graafian follicle, secondary follicle. (05 Mar 2000) |
| mature ovarian follicle | A follicle ready for ovulation; in the human ovary its antrum attains a diameter of 6 to 8 mm and presents a surface bulge; a first maturation (meiotic) division of the ovum usually occurs just prior to the rupture of the follicle. (05 Mar 2000) |
| granular layer of a vesicular ovarian follicle | The layer of small cells that forms the wall of an ovarian follicle. Synonym: granular layer of a vesicular ovarian follicle, granulosa, membrana granulosa, stratum granulosum ovarii. (05 Mar 2000) |
| right ovarian vein | <anatomy, vein> Begins as the pampiniform plexus at the hilum of the ovary and opens into the inferior vena cava. Synonym: vena ovarica dextra. (05 Mar 2000) |
| right ovarian vein syndrome | <syndrome> A condition characterised by intermittent abdominal pain due to ureteral compression by the right ovarian vein, occurring with most frequency on the right side, and thought to be due to aberrant crossing of the right ovarian vein over the ureter, generally at the level of the first sacral vertebra; dilation of the ovarian vein during pregnancy and unilateral ptosis of the kidney are thought to be contributing factors leading to intermittent ureteral obstruction and recurring bouts of pain and pyelonephritis. (05 Mar 2000) |
| growing ovarian follicle | A follicle having several layers of proliferating follicular cells surrounding the ovum, but separated from it by an extracellular glycoprotein layer (zona pellucida). (05 Mar 2000) |
| polycystic ovarian disease | <disease> A condition found among women who do not ovulate, characterised by multiple ovarian cysts and increased androgen production. (09 Oct 1997) |
