One of CSF's primary functions is to support and protect the brain. The fluid provides buoyancy within the cranium and helps the skull bear the weight of the three-pound brain. Cerebrospinal fluid also helps prevent brain injury from head trauma. It absorbs the shock of brain movement when the head suddenly accelerates or decelerates, enveloping the cranium in a thin cushion.
