Cerebrospinal fluid (CSF) Cerebrospinal fluid (CSF), clear, colourless liquid that fills and surrounds the brain and the spinal cord and provides a mechanical barrier against shock. Formed primarily in the ventricles of the brain, the cerebrospinal fluid supports the brain and provides lubrication between surrounding bones and the brain and spinal cord. When an individual suffers a head injury, the fluid acts as a cushion, dulling the force by distributing its impact.
The cerebrum -- which is just Latin for brain -- is the newest (evolutionarily) and largest part of the brain as a whole. It is here that things like perception, imagination, thought, judgment, and decision occur.The surface of the cerebrum -- the cerebral cortex -- is composed of six thin layers of neurons, which sit on top of a large collection of white matter pathways.The cortex is heavily convoluted, so that if you were to spread it out, it would actually take up about 2 1/2 square feet (2500 sq cm).ome of the sulci are quite pronounced and long, and serve as convenient boundaries between four areas of the cerebrum called lobes. The furthest forward is the frontal lobe (from the Latin word for forehead).
