Across
  1. 3. when an action potential occurs, positive charged ions flow into the neuron and negative charged ions flow out
  2. 6. glands that trigger fight or flight response
  3. 8. small sacs in the axon where neurotransmitters are stored
  4. 10. state of inactive neuron
  5. 12. passes messages away from the cell body to other neurons, muscles, or glands
  6. 14. mimics the neurotransmitter
  7. 17. covers axon of some neurons and helps speed neural impulses
  8. 19. form junctions with other cells
  9. 20. input nerves that go towards the central nervous system
  10. 22. receives messages from other cells
  11. 28. mobilizes energy in stressful situations
  12. 29. communicate internally in the brain and spinal cord
  13. 31. carry information from the brain and spinal cord to muscles and glands
Down
  1. 1. division of peripheral system that regulates key involuntary functions of the body
  2. 2. division of peripheral system that controls skeletal muscles
  3. 4. sends signals that calm cell
  4. 5. the master gland
  5. 7. calms body and conserves it’s energy
  6. 9. chemically controls various functions of cells, tissues, and organs with glands and hormones
  7. 11. charge inside neuron increases which cause depolarization of the neuron
  8. 13. brain region that controls pituitary gland
  9. 15. slightly negative charge in neuron and acts as a store of potential energy
  10. 16. gland that regulates metabolism
  11. 18. life support for the cell
  12. 21. blocks receptor sites
  13. 23. neuron pushes out positive ions and brings in negative ions
  14. 24. carry incoming information from the senses to brain and spinal cord
  15. 25. sends signals that stimulate the cell
  16. 26. chemical messenger inside the body
  17. 27. output nerves that go away from the central nervous system
  18. 30. it receives information, carries information down its lengths, and passes information on to others, muscles, and glands
