| 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 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, 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) |
| tenia fimbriae | The line of attachment of the choroid plexus of the lateral ventricle to the fornix. Synonym: tenia fimbriae, tenia of the fornix. (05 Mar 2000) |
