Aivokammioselkäydinnesteen, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that surrounds the brain and spinal cord. It acts as a cushion, protecting these vital organs from injury and shock. CSF also plays a crucial role in transporting nutrients to the brain and removing waste products.

The production of CSF occurs primarily in the choroid plexuses, which are specialized structures located within the ventricles of the brain. These fluid-filled cavities within the brain are interconnected and also continuous with the central canal of the spinal cord. CSF circulates through these ventricles and the subarachnoid space, a layer between the arachnoid mater and the pia mater, which are two of the meninges, the membranes that cover the brain and spinal cord.

The volume of CSF in an adult is typically around 150 milliliters, and it is constantly being replenished. The composition of CSF is vital, containing electrolytes, glucose, proteins, and white blood cells. Any significant alteration in the amount, pressure, or composition of CSF can indicate a medical condition. Analysis of CSF, through a procedure called a lumbar puncture, is a common diagnostic tool for various neurological disorders, including meningitis, encephalitis, and multiple sclerosis. Disturbances in CSF flow or absorption can lead to hydrocephalus, a condition characterized by an abnormal accumulation of CSF within the brain.
