Fallopian tube in an embryo. False-colour scanning electron micrograph (SEM) of the fimbriae in a ten week old embryo. The fimbriae are the terminal part of the Fallopian tube (oviduct or uterine tube) and connect it to the ovaries. The role of these petal-like structures is to trap the ovum after ovulation and channel it into the Fallopian tube. The journey of the ovum through the Fallopian tube towards the uterus will be eased by a viscous mucus secreted by glands and by movements of ciliated cells in the epithelium. Fimbriae become longer and more rugged in an adult woman. Magnification: x67 at 6x7cm size.
