(WCHN. 2004, October 11). The brain and spinal cord are enclosed in three fibrous connective tissue membranes called meninges. The membranes separating the soft tissue from the bones of the skull and vertebrae. (Saladin, K. p. 480).

Some activity within the CNS is quite simple REFLEX (automatic) activity. But much of its activity, particularly in the brain’s cerebrum, is complex and conscious. The cortex (outer layer) of the cerebrum has many functions. Different areas of the cortex are involved in processing or analyzing sensory information, sending signals to direct muscle movements, or in other activities such as reasoning, memory, or creative thought. (Kindersley, Dorling. 2007). Diseases and disorders that may affect the brain or spinal cord can be caused by strokes (vascular disorder), tumors or trauma (structural disorder), infections, functional disorders, and degeneration (autoimmune). Symptoms tend to vary per patient regarding severity of pain with a time of onset whether it is acute or persistent (degenerative) and location. However, if the brain suffers damage, the result can be consequential verses the spinal cord that is protected by vertebrae and the lesser of the two divisions of the CNS. Without the proper functioning of the brain, the result would be compared to that of mush, hence, leaving one with nothing, no control center that, in turn affects the rest of the nervous
