Across
  1. 3. the small gap between two neurons, where nerve impulses are relayed by a neurotransmitter from the axon
  2. 4. the middle section of your spine
  3. 5. this controls your hormone system
  4. 7. the way a nerve cell communicates with another cell
  5. 9. this connects your brain to your lower back
  6. 10. relays sensory and motor signals, as well as regulation of consciousness and alertness
  7. 15. a small part of the brain that is mostly hidden from view when you are looking at the outside of the brain
  8. 16. appendages that are designed to receive communications from other cells
  9. 17. the largest and uppermost portion of the brain
  10. 18. predominates in the quiet “rest and digest” conditions
  11. 20. is responsible for processing somatosensory information from the body
  12. 21. the fundamental units of the brain and nervous system
  13. 22. is important for voluntary movement, expressive language and for managing higher level executive functions
  14. 23. a complex organ that controls thought
  15. 24. a part of the nervous system responsible for control of the bodily functions
  16. 25. is responsible for visual perception, including color, form and motion
  17. 28. controls many subconscious body functions, like breathing and maintaining your heart rate
  18. 29. carries nerve impulses away from the cell body
  19. 30. the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system
  20. 31. the system that controls most functions of the body and mind
Down
  1. 1. provides senses of sight, hearing, smell, taste, and touch
  2. 2. the lowest part of the brain and the lowest portion of the brainstem
  3. 6. the lower back region of your spinal column or backbone
  4. 8. processes auditory information with the encoding of memory
  5. 9. drives the “fight or flight” response in stressful situations
  6. 11. the developing vertebrate brain that is composed of the tectum and tegmentum
  7. 12. transmits impulses from the spinal cord to skeletal and smooth muscles
  8. 13. this makes postural adjustments in order to maintain balance
  9. 14. relays information between your brain and the rest of your body
  10. 18. a highway-like structure between the brain and the body
  11. 19. a set of 12 paired nerves in the back of your brain
  12. 26. provides mobility and stability to the head while connecting it to the relatively immobile thoracic spine
  13. 27. any cell of the body except sperm and egg cells
  14. 32. the nerve fibers responsible for bringing sensory information from the outside world into the brain
