Across
- 3. / what could cause a
- 4. guidance / process in development where the growing nerve fibers find their targets
- 5. tube / what the entire central nervous system originates from in the embryonic state, after evolving from the neural groove
- 6. crest / what the entire peripheral nervous system originates from in the embryonic state, after evolving from the boarder of the neural plate
- 10. migration / a process in CNS development where new neuron cells are positioned into the right places to form the correct special patterns
- 12. plate / forms when part of the ectoderm thickens and becomes a neuroectoderm
- 13. / the process that, if disturbed, may lead to a condition called microcephaly where brain size is reduced
- 15. zonethe location where cells migrate from on radial glial cells to their destination in the cortex
- 16. / entire process by which the neural plate folds in on itself to form the neural groove, later to form the CNS, when it fu ses. The border of the plate created will give rise to the entire PNS.
- 17. formation / the cortex forms in such a way, as it builds its 6 layers from the center and then up
- 18. layers of cortex / product, through inside-out formation, of radial glial cells bringing up migrating neural cells from the ventricular zone
Down
- 1. / what the neural tube grows into during vesticulation
- 2. / what would cause a response of a cell towards a chemical signal
- 6. / releases signaling molecules that guide neural plate thickening
- 7. / a sort of umbrella term for something that extends from the neural body
- 8. division / what must have happened when one differentiated cell is split from one step cell
- 9. glial cells / passengers are to trains as these are to cells migrating in cortex development
- 11. division / what must have happened for two differentiated cells to split from one stem cell
- 12. / the process through which neural stem cells differentiate into types of nerve cells
- 14. / the outermost layer of the gastrula
