Choroid plexus secretory cells, SEM
Choroid plexus secretory cells. Coloured scanning electron micrograph (SEM) of a freeze-fractured choroid plexus from a brain. The fracture plane (green) has revealed the vertical columns of secretory cells, whose tips make up the surface (upper right). The tips are swollen due to increased secretion of the cerebrospinal fluid (CSF) that they produce. The choroid plexus is a network of capillary blood vessels that is found in each of the four ventricles (fluid-filled cavities) of the brain. It produces some of the CSF that surrounds and protects the brain and spinal cord. Magnification: x5000 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate beauty of choroid plexus secretory cells, as seen through a colored scanning electron micrograph (SEM). The freeze-fractured choroid plexus from a brain reveals an astonishing view of vertical columns of secretory cells, with their tips forming the surface on the upper right. These tips appear swollen due to increased secretion of cerebrospinal fluid (CSF), which is vital for protecting and surrounding the brain and spinal cord. The choroid plexus, a network of capillary blood vessels found in each ventricle of the brain, plays a crucial role in producing CSF. This image provides us with an extraordinary glimpse into this complex process within our central nervous system. With a magnification level of x5000 at 6x7cm size, this SEM photograph captures not only the remarkable structure but also highlights its importance in maintaining our overall health. By delving into histology and sectioning techniques such as freeze fracture, scientists can unravel the secrets hidden within these tiny yet essential components. Science Photo Library brings together science and art by presenting breathtaking visuals like this one that showcase both normal anatomy and cellular production processes. Through images like these, we gain a deeper understanding and appreciation for the wonders that lie within our own bodies.
