Brain artery, SEM
Brain artery. Coloured scanning electron micrograph (SEM) of a freeze-fractured artery from the brain. The fracture plane has passed through the artery, showing the central space (lumen) that carries the blood. The arterial tube runs to upper left, passing under the brains arachnoid mater membrane (seen across top). The internal surface of a blood vessel is lined with endothelial cells. Magnification unknown

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate beauty of a brain artery. In this coloured scanning electron micrograph (SEM), we are given a glimpse into the complex world of our circulatory system. The freeze-fractured artery is displayed in all its glory, with the fracture plane perfectly capturing the central space known as the lumen, through which life-sustaining blood flows. The arterial tube gracefully winds its way towards the upper left corner of the image, hidden beneath the brain's arachnoid mater membrane that stretches across the top. This delicate membrane acts as a protective layer for this vital pathway within our bodies. Examining closer, we can see that every inch of this blood vessel's internal surface is lined with endothelial cells. These specialized cells play an essential role in maintaining healthy circulation throughout our body. While it remains unknown at what magnification this stunning image was captured, one thing is certain – it offers us a rare glimpse into the microscopic wonders that make up our anatomy. As we marvel at this freeze-fractured sectioned artery, let us appreciate and acknowledge both its normalcy and significance within our cerebral vascular system.
