  • 3. SAY THE COLOR- NOT THE WORD!
  • 4. 33.2 ORGANIZATION OF NERVOUS SYSTEM*The Central Nervous System is the brain and the spinal chord.
  • 5. PERIPHERAL NERVOUS SYSTEM*The Peripheral Nervous System- consists of the sensory and motor neurons that carry information to and from the CNS.
  • 6. THE BRAINFacts about your Brain:• *The brain is the control center of the body• *Each part of the brain controls different thoughts or actions of the body.• You have over 100 Billion neurons• The Cerebrum is the largest part and is divided into two halves• The two halves communicate through a bundle of nerves.
  • 7. PARTS OF THE BRAIN*Cerebrum- largest part of the brain; controls muscles, thinking, learning, memory, decision making, and interpreting signals from the sense organs.
  • 8. PARTS OF THE BRAIN*Cerebellum- located below the cerebrum, helps to coordinate muscle movements.
  • 9. PARTS OF THE BRAIN*Brainstem connects the brain to the spinal cord.*Medulla is in the lower part of the brainstem. This control involuntary body functions such as breathing, digestion, and heart rate.
  • 10. SPINAL CORD*The spinal cord is also part of the CNS. (central nervous system)*The spinal cord sends messages from the brain to the rest of the body, and back again.It is a ropelike structure made of many neurons.It runs from the base of the brain down to the lower part of the back and is protected by the backbone.
