Integrative functoin
Impulses are conducted into the CNS from peripheral neurons where they come together to create sensations, memories, or thoughts that are converted into perception.
When Conscious or Unconscious decisions are made the impulses travel along what and go where?
Travel along Peripheral neurons to the effectors.
What are Effectors

What is the Autonomic Nervous system
Involuntary- Cardiac and smooth muscle groups.
What is the Somatic Nervous system
Voluntary-skeletal muscles
