Coloured SEM showing the ovulation process
Ovulation. Coloured scanning electron micrograph of the ovulation process. The egg (red at centre) has ruptured the external surface of the ovary (dark green), known as the germinal epithelium, and has started its journey through the Fallopian tube towards the uterus. The image clearly shows the thick glycoprotein layer (red), the zona pellucida, which entirely surrounds the egg. The egg is also partly surrounded by cells (granulosa cells light green) and fluid (liquor folliculi yellow), which formerly provided nutrients and protection to the egg in the ovary. Magnification: x1850 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate process of ovulation in stunning detail. In this coloured scanning electron micrograph, we witness the moment when an egg, represented by a vibrant red hue at the centre, ruptures through the external surface of the ovary. This outer layer, known as the germinal epithelium and depicted in dark green, marks the beginning of its remarkable journey towards the uterus through the Fallopian tube. The image also highlights a crucial component surrounding the egg - a thick glycoprotein layer called zona pellucida. This distinct red ring entirely envelops and protects the egg throughout its passage. Surrounding it are delicate granulosa cells depicted in light green that once provided nourishment and safeguarded this precious entity within its ovarian dwelling. Furthermore, we can observe liquor folliculi – a fluid shown in yellow – which played an essential role in nurturing and supporting this developing egg during its time within the ovary. With a magnification level of x1850 at 6x7cm size, this photograph offers us an extraordinary glimpse into one of nature's most miraculous processes: human ovulation. It serves as a testament to both our understanding of reproductive anatomy and our appreciation for life's intricate mechanisms.
