Cerebrospinal fluid. Definition

Medical Definition: Cerebrospinal fluid

Clear fluid that circulates in the cavities of the brain and spinal cord and around these, and between two of the meninges (thin layers of tissue that cover and protect the brain and spinal cord). Circulates through the brain ventricles and the spinal canal and brain stored in tanks. Cerebrospinal fluid is produced by a tissue of the ventricles (cavities) of the brain called the choroid plexus. Cerebrospinal fluid can become cloudy due to the presence of leukocytes or the presence of bile pigments. Many diseases alter its composition and its study is important and often decisive in meningeal infections, and bleeding carcinomatosis. Also called CSF.
