Spinal Cord Ependymal Cells
The ventricles of the brain and the central canal of the spinal cord are lined with ependymal cells.
- The cells are often cilated and form a simple cuboidal or low columnar epithelium.
- The lack of tight junctions between ependymal cells allows a free exchange between cerebrospinal fluid and nervous tissue.
- Ependymal cells can specialise into tanycytes, which are rarely ciliated and have long basal processes.
Tanycytes form the ventricular lining over the few CNS regions in which the blood-brain barrier is incomplete.
- Floor of the third ventricle with processes extending deep into the hypothalamus.
- They do form tight junctions and control the exchange of substances between these regions and surrounding nervous tissue or cerebrospinal fluid.
