Neuroscience
Across
- 4. Chemical process by which pioneer axons are directed towards their target location.
- 12. First step of neural development. Radial cells give rise to the neurons of the cortex.
- 13. First layer that forms during cell migration.
- 15. Cells that differentiate into neuronal and glial cells to eventually from all the glial and neuronal cells within the CNS.
- 16. The preliminary nervous system of an embryo that eventually becomes the central nervous system.
- 17. Layer of cells that becomes Layer I of the cerebral cortex after cell migration.
- 18. The outermost tissue layer of an embryo in early development that becomes the neural plate.
- 19. End of a neurite that guides the axon or dendrite into the correct target location
- 20. Stage of embryonic development in which the neural plate folds in on itself to form the neural tube.
Down
- 1. Cell division that results in two identical daughter radial glial cells
- 2. The buildup of CSF in the ventricles of the brain. Causes increased intracranial pressure and can be fatal
- 3. Cell division that results in one radial glial cell and one neural precursor cell.
- 5. Layers develop in an inside-out pattern, consists of Layer I, Layer II, Layer III, Layer IV, Layer V and Layer VI.
- 6. The part of the ectoderm that folds into the neural plate during cell development.
- 7. Neural progenitors that that give rise to all the neurons within the cortex,
- 8. Projections coming from the cell body of a neuron, can include axons or dendrites.
- 9. The step of neural development that follows proliferation. Cells move towards their final location.
- 10. Region that is lateral to the neural plate and which detaches from the neural plate when it becomes the neural tube. Eventually becomes all the cells of the PNS.
- 11. Bulge-like features that form on the neural tube shortly after the tube closes. Three primary are called forebrain, midbrain, and hindbrain.
- 14. the theory that the growth gone of a neurite is guided to its target
