Across
  1. 4. Bundles of axons in PNS (synonym: PNS-nerves).
  2. 9. Brain and spinal cord; integration/control center.
  3. 10. Control center for sensory/motor/cognitive functions.
  4. 12. Clusters of neuron cell bodies in PNS (synonym: ganglia).
  5. 13. Detection of internal/external stimuli.
  6. 15. PNS pathway transmitting sensory input to CNS.
Down
  1. 1. Conducts signals between brain/PNS; mediates reflexes.
  2. 2. Processing sensory input to make decisions.
  3. 3. Nerves and ganglia outside CNS.
  4. 5. Carries conscious sensory info (touch, pain).
  5. 6. Afferent neurons conveying sensory information.
  6. 7. Activation of effectors (muscles/glands).
  7. 8. PNS pathway carrying motor commands from CNS.
  8. 11. Transmits unconscious info from organs.
  9. 13. Structures detecting stimuli (e.g., thermoreceptors).
  10. 14. Bundles of myelinated axons in CNS (synonym: white matter tracts).
