Cerebrospinal fluid (CSF) is a clear, colourless fluid that surrounds the brain and spinal cord. It is produced by structures called the choroid plexuses, which are located in the ventricles of the brain. These are primarily in the lateral ventricles but are also found elsewhere. The choroid plexuses are covered by ependymal cells that produce the CSF. The CSF acts as a cushion to protect the brain and spinal cord from injury, and it also helps to distribute nutrients and remove waste products from these tissues.
