Fluids around the brain
What types of fluids are around the human brain?
The fluid bathing the brain is called the cerebrospinal fluid abbreviated
CSF. It serves two functions. One, it cushions the brain against injury by preventing
it from banging into the inside of the skull. Second, it has a chemical composition
different from blood, optimized for the special functions of nerve cells. It is made
from the blood in the ventricles, the four spaces inside the brain.
