Across
  1. 5. the branching projections of a neuron
  2. 9. (3 words) brain and spinal cord comprise this system
  3. 11. cranial nerve that conducts impulses from the nose to the brain and functions in our sense of smell
  4. 12. specialized connective tissue cells that hold functioning neurons together and protect them; aka neuroglia
  5. 13. the loss of the ability to make voluntary movements
  6. 17. (2 words) part of ANS; conduct impulses from a ganglion to cardiac muscle, smooth muscle, or glandular epithelial tissue.
  7. 22. (3 words)nerves that lay outside the brain and spinal cord
  8. 27. a group of nerve-cell bodies located in the PNS
  9. 29. tough, fluid-containing membrane found surrounding the spinal cord and the brain
  10. 30. the elongated projection of a neuron
Down
  1. 1. (3 words) structures that regulate the body's automatic or involuntary functions
  2. 2. ________________ disease is a chronic nervous disorder resulting from a deficiency of the neurotransmitter dopamine in the cerebral nuclei of the cerebrum.
  3. 3. a crucial part of the brain that controls body temperature helps control our heartbeat, among other things
  4. 4. aka "water on the brain"; a condition where the CSF builds up in the brain because it cannot drain away
  5. 6. largest and uppermost part of the brain
  6. 7. largest organ of the CNS
  7. 8. (2 words) fluid found in the spinal column and in the brain
  8. 10. microscopic space that separates the axon ending of one neuron from the dendrites of another neuron
  9. 14. part of the brain responsible for muscle coordination; maintenance of equilibrium and posture
  10. 15. skin surface areas that are supplied by a single spinal nerve
  11. 16. another, more common name for Herpes zoster, a unique viral infection that almost always affects the skin of a single dermatome
  12. 18. (2 words) a self-propagating wave of electrical disturbance that travels along the surface of a neuron's plasma membrane
  13. 19. (2 words) structure that connects the two halve or hemispheres of the cerebrum
  14. 20. nerve cells
  15. 21. part of the brain that helps produce sensations, associates sensations with emotions and plays a part in the alerting mechanism
  16. 23. a chemical by which neurons communicate
  17. 24. a type of Glia that help hold nerve fibers together and also produce the fatty myelin sheath that envelops nerve fibers located in the brain and spinal cord
  18. 25. _________________ nervous system is part of the ANS and performs such functions as speeding up heart rate, secreting adrenaline & delaying emptying the bladder
  19. 26. (2 words) upward extension of the spinal cord; the "vital centers" are located here.
  20. 28. a group of peripheral nerve fibers (axons) bundled together like the strands of a cable
