What do ependymal cells produce in the central nervous system?

Ependymal cells play a crucial role within the central nervous system by producing cerebrospinal fluid (CSF). These specialized glial cells line the ventricles of the brain and the central canal of the spinal cord. They have cilia that help to circulate the CSF, which serves to cushion the brain, remove waste, and provide nutrients.

The production of cerebrospinal fluid is essential for maintaining the proper environment for neurons, facilitating communication within the central nervous system, and supporting overall neurological function. This fluid fills the subarachnoid space and plays a key role in protecting the brain and spinal cord from injury. The ability of ependymal cells to produce and regulate the composition of CSF underscores their important function in the maintenance of neural health.
