Across
  1. 3. scavenge pathogens and dead cells
  2. 4. plays an important role in emotion as well, especially in anger and aggression
  3. 5. receives inputs from the neocortex
  4. 8. thin layer that closely follows the contours of the brain
  5. 9. transmits signals between the brain and the rest of the body, including internal organs
  6. 10. is the large, two-lobed structure that constitutes the top of the brain
  7. 11. the key connection point to a person’s cerebellum
  8. 12. branch-like structures that receive messages from other neurons and allow the transmission of messages to the cell body
  9. 15. house of many ascending and descending tracts and parts of the reticulum formation and the anterior part of the hindbrain
  10. 18. tube-like structure that carries electrical impulse from the cell body to the axon terminals that pass the impulse to another
  11. 21. a circuit of midline structures that circle the thalamus
  12. 23. division located outside the skull and spine
  13. 24. dorsal surface of the midbrain
  14. 25. it is composed of myelinated axons (Myelin- gives off glossy white sheen)
  15. 26. ridges between fissures & sulci
  16. 28. are a network of cavities that are distributed throughout the brain
  17. 29. it is a band of tissues, nerves, and cells
  18. 30. composed of cell bodies and unmyelinated interneurons
Down
  1. 1. attached to the spinal cord on the left and right side
  2. 2. adheres the skull on one side and arachnoid mater on the other side
  3. 6. strands of connective tissue called arachnoid trabeculae
  4. 7. composed of two divisions: the brain and the spinal cord
  5. 13. also called the soma
  6. 14. cells that are specialized for the reception, conduction, and transmission of electrochemical signals
  7. 16. developed by Franz Nissl, German psychiatrist, in the 1880s
  8. 17. neurons with a short axon or no axon at all
  9. 19. called inferior colliculi
  10. 20. pronounced as "GLEE-a"
  11. 22. comes from the Greek word for “Membrane”
  12. 27. the division of the mesencephalon ventral to the tectum
