  1. 3. This can change the size of an organism and the number of cells. A disruption in this process may cause microcephaly.
  2. 6. An axon or a dendrite. Anything stemming away from the soma. ______ outgrowth is a process in which a neuron develops towards a target.
  3. 9. Cells travel from the ______ ___ to their intended layer of the cortex.
  4. 10. The rostral end of the neural tube forms these structures.
  5. 12. A region of the mesoderm that releases signaling molecules to thicken the answer to clue #3.
  6. 14. The answer to clue #19 moves the axon towards it target using cues in a process called ___ ______.
  7. 15. A substance that discourages the growth cone to stretch towards it. Causes the growth cone to develop away from it. Along with the answer to clue #22, it is a part of the process that answers clue #18. (2 words)
  8. 17. division A type of differentiation in which a stem cell produces two identical cells- both specialized cells such as glia. (2 words)
  9. 20. A secreted or membrane-bound substance which cause the growth cone to stretch towards it. Along with the answer to clue #23, it is a part of the process that answers clue #18. (2 words)
  10. 21. Comes from the neural groove. It generates the CNS. (2 words)
  11. 22. division A type of differentiation in which a stem cell produces two different cells- one stem cell, one specialized cell such as a glial cell. (2 words)
  12. 23. The birth of a neuron.
  13. 24. This can also be called a “neuroectoderm.” (2 words)
Down
  1. 1. The movement of a cell away from a substance.
  2. 2. This is how the answer to clue #2 forms. (3 words)
  3. 4. Cell migration across “train tracks” made of radial glial cells causes the __ ___ __ __ ____ to grow from inside out.
  4. 5. Comes from the border of the neural plate. It generates the PNS. (2 words)
  5. 7. A part of a developing neuron, powered by actin. It is at the end of a developing axon, and it extends towards a target in a process called “neurite outgrowth.” (2 words)
  6. 8. The second step of cortex development. Along with morphogenesis, this changes the shape of a developing organism. (2 words)
  7. 11. This is where neural stem cells come from. Neurons, astrocytes, oligodendrocytes are all derived from this.
  8. 13. The movement of a cell towards an intended target.
  9. 16. This is the process that forms the structures in clues #4 and #5.
  10. 18. These enable cell migration by acting as “train tracks.” (3 words)
  11. 19. A neuron in the cortex. (2 words)
