  1. 5. The sensory and motor neurons that connect the central nervous system(CNS) to the rest of the body.
  2. 6. These are in the brain and spinal cord. They process all incoming information and then make decisions about what responses would be appropriate.
  3. 9. The ________ connects the peripheral nervous system to the brain.
  4. 14. The___________ nervous system, like a parachute, calms the body down and brings it back to a normal resting state after an arousal producing event has passed.
  5. 15. Sensory or afferent neurons bring messages from the sensory receptors like ______ and ears to the brain and spinal cord for processing. We don’t know what we are seeing or hearing until our brain gets involved.
  6. 16. The body’s speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems.
  7. 17. The_______ or skeletal nervous system enables communication from the brain and spinal cord to our muscles connected to bones. Responses are carried out by this part of the PNS by motor neurons.
  8. 19. The brain and spinal cord.
Down
  1. 1. Reflexes or simple automatic responses are also controlled by the spinal cord pathway, called a ________.
  2. 2. Neurons within the brain and spinal cord; they communicate internally and process information between the sensory inputs and motor outputs.
  3. 3. The central nervous system (CNS) comprises the ______ and spinal cord.
  4. 4. A simple, automatic response to a sensory stimulus, such as the knee-jerk reflex.
  5. 7. The _______ nervous system arouses the body, prepares it for fight or flight at a time when there may be danger.
  6. 8. The peripheral nervous system (PNS) helps the CNS to communicate with the rest of the body by transmitting sensory information to the brain and delivering commands to ______ and glands.
  7. 10. These type of Neurons carry outgoing information from the brain and spinal cord to the muscles and glands.
  8. 11. These Neurons carry incoming information from the body’s tissues and receptors to the brain and spinal cord.
  9. 12. We have millions of sensory and motor neurons but _______ of interneurons!
  10. 13. These are bundled axons that form neural cables connecting the central nervous system with muscles, glands, and sensory organs.
  11. 18. The ________ nervous system has two divisions of its own, each helping to maintain homeostasis in the body.
