Epithelium Ependymal

The ependymal epithelium is the outer layer of neuroglial origin of the spinal cord and brain. It is most widespread in the tentorium of the choroid plexus and in some other areas of the brain and spinal cord (this is due to their origin from the spinal or cranial nerves, respectively).

It is also often found in the ventricles of the brain in the embryo and is an important part of the meninges and fills the tubules during human life.
