Across
  1. 3. Largest glial cells of the CNS that helps maintain BBB
  2. 4. This structural type of neuron is likely to be found as a sensory neuron in your skin
  3. 7. This division of the autonomic system controls your “flight or fight” response
  4. 10. This functional division delivers information FROM the CNS
  5. 12. This is the end of the axon where neurotransmitters are released
  6. 13. The cells with the ability to send electrical messages, generally cannot divide
  7. 16. Phagocytes of the CNS
  8. 18. This functional division brings information IN to the CNS
  9. 19. This part of the neuron is the area the impulse travels along
  10. 21. Myelinate axons of the CNS
  11. 22. Produce cerebrospinal fluid
  12. 23. This part of the neuron protects and insulates the axon, and is made from glial cells
  13. 25. Made up of the brain and spinal cord (abbreviation)
  14. 26. This structural type of neuron is uncommon and likely to be found in your retina
  15. 27. A type of functional neuron that brings information to the CNS
Down
  1. 1. This functional type of neuron only sends/receives messages from other neurons
  2. 2. These projections of a neuron receive signals
  3. 5. Cells that myelinate the axons of the PNS
  4. 6. This functional type of neuron is associated with movement, while it controls muscles it can deliver messages to other effectors as well
  5. 8. This division of the autonomic system is in control of “rest and digestion”
  6. 9. Often a motor neuron this structural type of neuron is also the most common found in your brain
  7. 11. These spaces between myelin sheaths help speed up the transmission of the signal along the axon
  8. 14. This division of the efferent system controls primarily skeletal muscles
  9. 15. These cells of the PNS wrap around neurons to support
  10. 17. One of the two main components of the CNS
  11. 20. A category of cells that provide support and protection for neurons
  12. 24. The space in between the axon terminal of one neuron and the dendrites of another where neurotransmitters are released and absorbed
