- 4. A transient embryonic layer of tissue containing neural stem cells, principally radial glial cells, of the central nervous system of vertebrates.
- 6. This cortex layer consists mostly of stellate cells. The existence of these small cells in this layer gives that unique appearance to this layer.
- 10. A fundamental process in central nervous system development. The assembly of functioning neuronal circuits relies on this occurring in the appropriate spatio-temporal pattern.
- 14. These cells of the CNS that give rise to many, if not all, of the glial and neuronal cell types that populate the CNS. They do not generate non-neural cells in the CNS.
- 15. One of three germ layers—groups of cells that coalesce early during the embryonic life of all animals except maybe sponges, and from which organs and tissues form.
- 16. They generate a wide variety of cell and tissue types during embryonic and adult development including cartilage and bone, connective tissue, pigment and endocrine cells as well as neurons and glia amongst many others.
- 17. These are tiny sacs that transport material within or outside the cell. There are several types of these used for transport, secretion, and waste destruction.
- 18. In this style of division produces two daughter cells with different cellular fates.
- 19. The profess by which growing nerve fibers find their targets in the developing brain.
- 20. A thickened plate of ectoderm along the dorsal midline of the early vertebrate embryo that gives rise to the neural tube and neural crests.
Down
- 1. This layer of the cortex layer is the main input cortical station, it is specially developed within the sensory areas, and consists mostly of the stellate cells and a small portion of pyramidal cells.
- 2. In this style of division stem cells give rise to two progenies whose properties remain similar.
- 3. The most superficial layer of the cortex, laying directly under the pia mater.
- 5. Simply an increase in total cell number that is achieved through cell growth and division.
- 7. Any projection from the cell body of a neuron. This projection can be either an axon or a dendrite.
- 8. This layer of the cortex consists mostly of the pyramidal cells, and superficial cells of this layer are smaller than those in a deeper layer.
- 9. This is the deepest layer of the cortex that directly overlies the subcortical white matter, and contains mostly fusiform cells.
- 11. A process in which the neural plate bends up and later fuses to form the hollow tube that will eventually differentiate into the brain and the spinal cord of the central nervous system.
- 12. This layer of the cortex consists mostly of the medium and large pyramidal cells, and is the source of the output or corticofugal fibers.
- 13. The process by which new neurons are formed in the brain.
