HLTAID002 - PROVIDE BASIC EMERGENCY LIFE SUPPORT The nervous system

What is the primary purpose of the nervous system? All mental and physical activity is controlled by the nervous system – a complex network of cells that communicate with one another. The division of labour that exists within the nervous system allows it to control the human body precisely and efficiently. What are the two main organs of the central nervous system? The two main organs of the central nervous system are the brain and the spinal cord. The brain is the human body’s controlling organ. The spinal cord extends from the brain and then on to a network of nerves throughout the body. Information transmitted to and from the brain include sensory information (touch, taste, sight, sound, smell), motor functions and involuntary functions along with levels of consciousness.
