  2. 5. controls movement and coordination
  3. 6. regulates body temp., metabolism, pituitary gland, & pleasure
  4. 7. area of white matter that connects the 2 hemispheres
  5. 9. extension of the spinal cord; when cut it can cause death
  6. 11. a hormone that helps with alertness, focus, and motivation
  7. 13. the fatty material that insulates a neuron & helps deliver messages faster
  8. 15. (adrenaline) hormone responsible for flight or fight
  9. 17. transmits messages away from the cell body
  10. 18. part of brainstem that links medulla oblongata and thalamus
  11. 19. part of the autonomic system; functions as an emergency system; fight or flight response
  12. 21. one of the four sections of the brain; anterior part of the brain; responsible for higher cognitive functions
  13. 22. controls the voluntary activities of the body
  14. 26. nerve cells that are activated by sensory input from the environment
  15. 27. above the brainstem, between the cerebral hemispheres
  16. 28. outermost layer of the brain made up of gray matter
  17. 29. one of the four sections of the brain; located on the sides of the brain; responsible for processing auditory information
  18. 30. junction between two neurons
  19. 33. chemicals released to transmit signals between neurons
  20. 34. controls body activities involuntarily
Down
  1. 1. consists of brain & spinal cord; receives, interprets & gives instructions
  2. 2. area between brain and spinal cord
  3. 4. a stimulant; hormone in charge of pleasure
  4. 8. Consists of nerves that extend from the spinal cord & brain
  5. 10. transmit neural impulses from the spinal cord to skeletal and smooth muscles; control all our muscles movement
  6. 12. transmit messages toward the cell body
  7. 14. produces sensations of arousal or alertness
  8. 16. the main neurotransmitter of the parasympathetic nervous system; part of autonomic nervous system
  9. 20. part of the autonomic system; functions as an emergency system; rest and digest
  10. 23. one of the four sections of the brain; near the back end of the brain; responsible for visual perception
  11. 24. managing mood, appetite, sleep, and dreaming
  12. 25. one of the four sections of the brain; upper area of the brain; processes sensory information
  13. 31. also called terminal branches
  14. 32. allows for communication between sensory and motor neurons; also known as interneuron
