Brain lining. Coloured scanning electron micrograph (SEM) of the lining of the brain, showing the ciliary hairs (green) of ependymal cells. Ependymal cells are a type of neuroglia (glial cells) that line the ventricles of the brain and produce cerebrospinal fluid (CSF). CSF has a number of functions, including buffering the brain from shock, transporting hormones around the brain and absorbing waste products. The ciliary hairs are used to help circulate the CSF. Magnification x2000 when printed 10 centimetres wide.
