Across
  1. 2. base of the cerebrum; relays information between the brain and the spinal cord
  2. 5. covers long axons to insulate the elecrical signal
  3. 6. Lobe that is primarily involved in sensory perception; allows you to process senses such as touch, pain, temperature, and pressure.
  4. 8. excitable cells that respond to stimuli by conducting impulses to transmit signals
  5. 9. unmyelinated gaps in the myelin sheath that aid in increasing the velocity of nerve signal conduction
  6. 13. supportive cells that provide nutrition, insulation, and help with signal transmission
  7. 16. bundles of axons that extend from the brain and spinal cord to the rest of the body.
  8. 18. the ultimate control center of the body overseeing all communication among the organ systems
  9. 20. Lobe involved in taste; planning and problem solving
  10. 21. Directs sensory signals to the proper region of the cerebrum to process those signals
  11. 22. control center for heart rate and respiration
Down
  1. 1. Lobe that allows you to process auditory information and remember short-term and long-term memories
  2. 3. the folded surface of the cerebrum
  3. 4. the main receptor of signals; input region of a neuron
  4. 7. the end of the axon that releases neurotransmitters at a synapse when a nerve impulse is received; the secretory region of a neuron
  5. 10. Lobe where visual information from the eyes is processed.
  6. 11. "bridge" of the brainstem; sends information between your cerebrum and cerebellum
  7. 12. "the little brain"
  8. 14. Helps your body maintain homeostasis
  9. 15. generates and transmits nerve impulses; the conducting region; also known as a nerve fiber
  10. 17. the largest part of the brain that is divided into 4 lobes
  11. 19. The uppermost part of the brain stem that allows the body to react reflexively to visual and auditory information
