What are nervous system disorders?

Nervous system disorders can involve a range of conditions that may be chronic or may be triggered by secondary factors. The nervous system is a complex, sophisticated system that regulates and coordinates body activities. It is made up of two major divisions:

  • Central nervous system: Consisting of the brain and spinal cord
  • Peripheral nervous system: Consisting of all other neural elements

In addition to the brain and spinal cord, principal organs of the nervous system include the following:

  • Eyes
  • Ears
  • Sensory organs of taste
  • Sensory organs of smell
  • Sensory receptors located in the skin, joints, muscles, and other parts of the body
