Ependymal

Definition

Ependymal cells are a type of glial cell that lines the ventricles in the brain and the central canal of the spinal cord. They play a crucial role in the production and circulation of cerebrospinal fluid (CSF).

5 Must Know Facts For Your Next Test

1. Ependymal cells have cilia on their apical surface which help circulate cerebrospinal fluid.
2. They form a barrier between the cerebrospinal fluid and nervous tissue.
3. Ependymal cells can differentiate into other types of glial cells, particularly astrocytes.
4. These cells participate in the formation of the blood-CSF barrier.
5. Ependymal cells are involved in neurogenesis, especially in regions like the subventricular zone.
