Across
  1. 3. receives emotion/Conscious thought, translating them. Comprised of the cerebrum(language, thought, decision making, left and right hemispheres)
  2. 4. Processes auditory signals, as well as understanding written/spoken language
  3. 6. interprets sensory information from the skin
  4. 8. receives and interprets visual signals
  5. 13. A Progressive autoimmune disease causing damage to myelin sheaths in brain and spine
  6. 14. save neuron energy, speed up energy transmission(50%), saltatory conduction- leaping energy from node to node
  7. 15. Comprised of the brain and spinal cord, skull/vertebrae, surrounded by cerebrospinal fluid.
Down
  1. 1. Forms myelin sheaths in CN
  2. 2. Known as Lou-Gehrigs disease, causing progressive damage to myelin sheaths in the spinal cord region involved in motor function of skeletal muscle, often resulting in death due to interruption of the impulse transmission to the diaphragm and intercostal muscle
  3. 5. short uninsulated gaps between Schwann cells
  4. 7. initiates motor activity(consisting of speech and thought)
  5. 9. produced by glial cells
  6. 10. CNS, superhighway for action potentials, consisting of myelinated ascending(sensory) and descending(motor) axons(nerve tract)
  7. 11. Oldest part of the brain, comprised of the cerebellum which controls basic movement like tying shoes, swinging a bat, using a keyboard, etc. Consuming excessive alcohol disrupts normal operation
  8. 12. Makes up 80% of the nervous system
  9. 16. Special junction between axon-terminus of a neuron and its target cell, processes impulse transmission
