The brain is the control centre for your body and it sits in your skull at the top of your spinal cord. The brain has three main parts. 1  The cerebellum (say se-re-bell-um). The brain stem, that controls a lot of the 'automatic' actions of your body such as breathing and heart beat, and links the brain to the spinal cord and the rest of the body.
Functions of the Cerebrospinal Fluid The main function of the cerebrospinal fluid is to act as a shock absorber thereby cushioning the brain. There is a very slight difference in the specific gravity of the brain and CSF which allows the brain to be âsuspendedâ in the CSF. With a moderate blow or sudden jerking of the neck and head, the brain will move with the skull and not collide with it.
