• The nervous system controls all automatic and conscious actions and sensations in all parts of the body
• The nervous system is divided into two systems:

  Central nervous system (CNS)

  Peripheral nervous system (PNS)
• The central nervous system is controlled by the brain and is connected to the spinal cord.

  Signals flow from the nerves to the spinal cord, then to brain and back again.

  The brain is a control centre and organises millions of signals
