Across
  1. 2. nodule-like structures found on the posterior roots of each spinal nerve, which contain the soma (or cell bodies) of the afferent sensory nerves carrying sensory signals back to the central nervous system
  2. 5. Keeps body in homeostasis; master hormone regulator
  3. 7. memory consolidation
  4. 12. fight or flight response;readies the body for activity, use of energy (increases in heart rate, blood pressure, and focus)
  5. 14. Manage thinking, emotions, personality, judgment, self-control, muscle control, and movements, memory storage and more
  6. 16. Process and interpret somatosensory input
  7. 17. Enables communication between two cerebral hemispheres
  8. 19. contains myelin; fatty substance that wraps around axons
  9. 21. Immune cells of the brain
  10. 22. The medulla helps control heart rate, breathing, and blood pressure
  11. 24. Primarily responsible for motor control
  12. 25. brain and spinal cord
  13. 26. away from the brain (CNS)
  14. 27. Relay station between cerebellum and rest of the brain and spinal
  15. 28. Key part of emotional control and processes (fear response)
  16. 30. glial cells that line cavities and produce CSF
  17. 31. contains interneurons, as well as the dendrites and cell bodies of projection neurons
  18. 33. Muscle control; balance and movement
  19. 34. Visual perception, color, form, and motion
Down
  1. 1. Glial cell that forms the myelin around neurons in the CNS
  2. 3. towards the brain (CNS)
  3. 4. refers to back; sensory information enters here
  4. 6. Glial cell that forms the myelin around neurons in the PNS
  5. 8. everything outside of brain and spinal cord
  6. 9. interacts with external environment; voluntary
  7. 10. Relays motor and sensory signals to cerebral cortex
  8. 11. refers to front; motor commands exit here
  9. 13. dendrite, cell body, axon, axon terminals
  10. 15. regulates internal environment; involuntary
  11. 18. Eye movements and pain modulation
  12. 20. A group of interconnected structures that help us sense and interpret surroundings, and to make appropriate behavioral responses
  13. 23. rest and digest; readies the body for storage of energy and rest (decreases in heart rate, blood pressure, increased digestion)
  14. 29. Processing auditory information; encoding of memory
  15. 32. Glial cells that make up majority of CNS; blood brain barrier
