  4. 12. chemical substances that act as messengers in the body
  5. 15. the molecule that is going to be changed by a chemical reaction
  6. 21. a nerve fiber that sends nerve impulses away from the cell body
  7. 22. organelles where cellular respiration occurs
  8. 24. endocrine glands situated on the kideys

  11. 27. special cells that detect stimuli
  12. 29. a nerve cell
  13. 30. muscles or glands that put the messages into effect
  1. 1. the lower half of the brain stem
  2. 3. the nerve that carries messages to the brain from the retina at the back of the eye
  3. 4. the movement of particles of a substance from an are of high concentration to an area of low concentration
