Examples

• The ependyma produces cerebrospinal fluid that circulates through the brain's ventricles.
• Damage to the ependyma can disrupt the normal flow of cerebrospinal fluid.
• The ependyma is composed of specialized cells called ependymal cells.
• During development, the ependyma lines the neural tube.
• Ependymomas are tumors that arise from the ependyma.
