Across
  1. 2. the basic building block of the nervous system; receiving information
  2. 3. the collection of structures in the middle of the brain responsible for coordinating movement patterns, sleep, and arousal
  3. 5. part of a neuron that contains the cell nucleus and other structures that help the neuron carry out its functions
  4. 6. a substance that mimics and enhances a neurotransmitter's direct effect
  5. 7. a long, tube-like structure that conveys impulses away from a neuron's cell body
  6. 9. the part of the nervous system consisting of the brain and spinal cord
  7. 11. a chemical messenger released by neurons that travels across the synapse and allows neurons to communicate with one another
  8. 12. the small brain structure beneath the thalamus that helps govern drives and hormones
  9. 14. a subdivision of the PNS that connects the CNS to sensory receptors and controls skeletal muscles
  10. 17. immature cells that have the potential to develop into almost any type of cell
  11. 19. the brain's ability to reorganize and change its structure and function throughout the life span
  12. 20. branching fibers of neurons that receive neural impulses from other neurons
Down
  1. 1. the diffuse set of neurons that helps screen incoming information and controls arousal
  2. 4. the process by which new neurons are generated
  3. 8. the part of the nervous system composed of the nerves and neurons connecting the CNS to the rest of the body
  4. 10. a segment of DNA that occupies a specific place on a particular chromosome and carries the code for hereditary transmission
  5. 13. the process by which heritable traits that increase an organism's chances of survival
  6. 15. a substance that blocks normal neurotransmitter functioning
  7. 16. provide structural, nutritional, and other support for neurons
  8. 18. a chemical messengers manufactured and secreted by the endocrine glands
