Abstract
The central nervous system (CNS) is composed of the brain and the spinal cord, while the peripheral nervous system (PNV) consists of spinal and cranial nerves which branch from the spinal cord and the brain, respectively. The human brain is the main organ controlling all body functions such as motion, emotions, memory, hearing, etc. Information is delivered to the human brain through the five senses: sight, smell, touch, taste and hearing.
