Nervous System

• What makes up the Central Nervous System (CNS)

  Brain and spinal cord
• What makes up the Peripheral Nervous System (PNS)

  Somatic Nervous System- controls voluntary movements

  Autonomic Nervous System- controls involuntary responses.

  ANS split into the Sympathetic Division and Parasympathetic Division
• Main functions of the Nervous system

  Collect, process and respond to info in environment

  Coordinate different organs and cells in body
• Spinal Cord

  Relay info between brain and rest of the body

  Allows body to monitor and regulate involuntary body processes and coordinating voluntary movements
• Sympathetic Branch of ANS

  Involved in responses that help us to deal with emergencies (fight or flight)

  Helps body prepare for the rapid action needed when under attack
• Parasympathetic Branch of ANS

  Body's resting state

  Involved in energy conservation and digestion
• The actions of both CNS and PNS work in opposition to on another (antagonistic)
