In the female reproductive system, the fimbria (plural, fimbriae) is a fringe of tissue around the ostium of the Fallopian tube, in the direction of the ovary.
An ovary is not directly connected to its adjacent Fallopian tube. When ovulation is about to occur, the sex hormones activate the fimbriae, causing it to swell with blood and hit the ovary in a gentle, sweeping motion. An oocyte is released from the ovary into the peritoneal cavity and the cilia of the fimbriae sweep the ovum into the Fallopian tube.
Not all fimbriae, but only the ovarian fimbria[1] (fimbria ovarica) is long enough to reach to ovary.
