Cerebrospinal fluid (CSF) Cerebrospinal fluid (CSF), clear, colourless liquid that fills and surrounds the brain and the spinal cord and provides a mechanical barrier against shock. Formed primarily in the ventricles of the brain, the cerebrospinal fluid supports the brain and provides lubrication between surrounding bones and the brain and spinal cord. When an individual suffers a head injury, the fluid acts as a cushion, dulling the force by distributing its impact.
Ependymoma. An ependymoma is a type of brain tumor that arises from cells that line the ventricles of the brain and the central canal of the spinal cord. The ventricles are fluid filled spaces inside the brain.There are four ventricles, two lateral ventricles, the 3rd ventricle and the 4th ventricle.An ependymoma can arise in any of these areas since all of them are lined with ependymal cells (the name for the cells lining the venricles).hey can occur in any of the ventricles or in the spinal cord. Occasionally, after originating in one place, they spread to other areas through the cerebrospinal fluid, the liquid that is inside and surrounding the brain and spinal cord. Both adults and children can develop an ependymoma.
