False-colour SEM of fimbriae in an embryo
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

EDITORS COMMENTS
This print showcases the intricate beauty of fimbriae in a ten-week-old embryo's Fallopian tube. The false-color scanning electron micrograph (SEM) reveals these delicate petal-like structures that play a crucial role in the reproductive process. Serving as connectors between the ovaries and the Fallopian tube, fimbriae have an essential task: to capture the ovum after it is released during ovulation and guide it into the Fallopian tube. As we observe this mesmerizing image, we gain insight into how nature has designed these fimbriae to facilitate fertilization. Along its journey towards the uterus, the ovum encounters two mechanisms that aid its passage. Firstly, glands secrete a viscous mucus that lubricates and eases its movement through the narrow passages of the Fallopian tube. Secondly, ciliated cells within the epithelium create gentle movements that propel and guide it along. Interestingly, this SEM also highlights an intriguing aspect of human development - as women reach adulthood, their fimbriae grow longer and acquire a more rugged appearance. This adaptation likely enhances their efficiency in capturing ova for successful conception. With a magnification of x67 at 6x7cm size, this photograph offers us an extraordinary glimpse into one of nature's most remarkable processes – reproduction within our own bodies. It serves as a testament to both scientific curiosity and artistic appreciation for life's intricate details captured by Science Photo Library.
