Across
  1. 4. The "little brain" that controls your complex muscle movements, helping you to maintain balance.
  2. 8. The part of a neuron that transmits information from the nucleus to different parts of the body.
  3. 9. The two-part (central and peripheral) system that controls a huge number of activities in your body. TWO WORDS
  4. 11. Bundles of neuron axons running together. They gather information from inside and outside your body and send it to your brain. They also carry commands from your brain to your body.
  5. 13. Contains nerves that spread out from the central nervous system to the outer edges of the body. THREE WORDS
  6. 16. Chemicals at the end of an axon that transmit infomration from one neuron to another.
  7. 19. Neurons that send information from your brain and spinal cord to your body, telling your muscles and other organs what to do. TWO WORDS
  8. 20. The part of a neuron that contains the nucleus and receives information from the dentrites. TWO WORDS
  9. 21. The most important cells in the nervous system. They receive, store, and process information, as well as send messages throughout the body.
Down
  1. 1. The part of the peripheral nervous system that works automatically. It controls your smooth muscles so your organs can function without you thinking about them. THREE WORDS
  2. 2. The largest part of the brain where most of your conscious actions are controlled, and thoughts are thought.
  3. 3. The part of the peripheral nervous system that is responsible for the voluntary movements you make. THREE WORDS
  4. 5. The fatty tissue wrapped around an axon that allows information to travel more quickly down the axon. TWO WORDS
  5. 6. The very tiny space between the axon terminal of one neuron and the dentrite of another.
  6. 7. Contains the brain and spinal cord. THREE WORDS
  7. 10. The folded outer part of your cerebrum. TWO WORDS
  8. 12. Neurons that send information to your spinal cord and brain for processing. TWO WORDS
  9. 14. Connects the brain to the spinal cord and controls things like your breathing and heartbeat.
  10. 15. A type of neuron that is found between (and connects) other neurons.
  11. 17. One of the "arms" of a neuron that reaches out in many directions and gathers information.
  12. 18. A function of the brain that sorts and processes information, making it underatandable and usable.
