1048 Words5 Pages

The nervous system is a compound set of specialized cells and nerves that integrate the voluntary and involuntary actions of the body and send signals between different parts of the body.When it comes to structure, the nervous system has two main parts: the peripheral nervous system and the central nervous system. The peripheral nervous system is made up of ganglia and nerves outside the brain and spinal cord. The central nervous system consists of the spinal cord, nerves and brain.

If the individual's sleep latency period is eight minutes or less, the person typically has excessive daytime sleepiness. However, having a sleep latency period less than eight minutes does not necessarily mean the individual has narcolepsy. Narcolepsy is extremely difficult to diagnose because many of the symptoms of narcolepsy can stand alone as their own disorders.
