Ependymal Cells [edit]. The ependyma is made up of ependymal cells, ependymocytes, a type of glial cell. These cells line the CSF-filled ventricles in the brain and the central canal of the spinal cord. The cells are ciliated simple columnar epithelium-like cells.pendyma is the thin epithelium-like lining of the ventricular system of the brain and the central canal of the spinal cord.
Ependymomas arise from the ependymal cells that line the ventricles of the brain and the center of the spinal cord. These tumors are divided into four major types: Subependymomas (grade I): Typically slow-growing tumors. Myxopapillary ependymomas (grade I): Typically slow-growing tumors.
