Neurulation |
Process of thickening of neural plate and envagination |
|
|
Neural plate forms what during neurulation |
Neural crest and neural tube |
|
|
Neural tube fuses where first? |
Cervical area. Somite 4. Day 21 |
|
|
Epithelial cells lining the neural tube give rise to what? |
Most cells of the CNS (except microglia and dura from mesoderm) |
|
|
Microglia and dura arise from what? |
Mesoderm |
|
|
Neural tube is comprise of what three layers? |
Ependymal, mantle, marginal layers |
|
|
Neural tube layers give rise to what? Ependymal layer Mantle layer Marginal layer |
Ependymal layer: ependymal lining and choroid plexus epithelium Mantle layer: gray matter Marginal layer: white matter |
|
|
Neural Crest cell derivatives |
Most tested: pia and arachnoid membrane, dorsal root ganglia, sensory ganglia, autonomic and enteric ganglia, Schwann cells, melanocytes, adrenal chromaffin cells, skeletal and connective tissue components of the head arising from pharyngeal arches |
|
|
Alar plate and basal plate give rise to what |
Alar (dorsal) plate becomes dorsal SC containing sensory nuclei. Basal (ventral) plate becomes ventral SC containing motor nuclei. |
|
|
Prosencephalon becomes what? |
Prosencephalon (forebrain) become telencephalon (becomes cerebellum/WM/BG/lat vents)and diencephalon (thal, hypothal, epithal, retina, 3rd vent) |
|
|
Mesencephalon becomes what? |
Mesencephalon (midbrain) becomes mesencephalon (brainstem: midbrain and cerebral aquaduct) |
|
|
Rhombencephalon becomes what? |
Rhombencephalon (hind brain) becomes melencephalon (brain stem:pons and cerebellum) and mylencephalon (brain stem: medulla and 4th vent) |
