  1. 1. Main control center that detects blood changes and stimulates the pituitary gland.
  2. 2. Receptors that detect oxygen carbon dioxide and pH levels in the blood.
  3. 4. The regulation and maintenance of a stable internal environment in the body.
  4. 6. Neurons that convey messages from receptor cells to the central nervous system.
  5. 7. The junction between two nerve cells where signals are transmitted.
  6. 8. Organs of the endocrine system that manufacture and release hormones.
  7. 11. Cells signaling to themselves to regulate their own activity.
  8. 13. Endocrine gland near the brain center that produces melatonin.
  9. 15. Coordination of different body systems to perform overall functions and sustain life.
  10. 16. Neurons that send commands from the brain to muscles or glands.
  11. 17. Hormone secreted by adrenal glands during stress to prepare for vigorous activity.
  12. 19. An individual cell of the nervous system.
  13. 22. ARC A simple fast neural pathway that processes involuntary responses.
  14. 23. Branch-like parts of a neuron that receive signals from other neurons.
  15. 24. Involuntary waves of muscle contraction that move food through the digestive system.
  16. 27. Protective fatty coating that insulates electrical signals in nerve fibers.
