1When does neural development begin?
- A10 days after fertilization
- B22 days after fertilization
- C5 days after fertilization
- D15 days after fertilization
2Order the layers from outermost to innermost.
- Aectoderm, mesoderm, endoderm
- Bendoderm, ectoderm, mesoderm
- Cmesoderm, endoderm, ectoderm
3The notochord is in the
- Aectoderm
- Bmesoderm
- Cendoderm
4What does the notochord do?
- Agenerates electrical communication for cell specialization
- Bgenerates chemical communication for cell specialization
5The neural plate becomes
- Athe brain
- Bthe spinal cord
- Cthe brain and the spinal cord
6True or false? The neural plate is above the notochord.
- ATrue
- BFalse
7[blank_start]Proliferation[blank_end] of new cells on either side of the [blank_start]neural plate[blank_end] creates the [blank_start]neural groove[blank_end] which is the folding of the [blank_start]neural plate[blank_end].
- AProliferation
- BThickening
- CNeurogenesis
- Dneural plate
- Eneural groove
- Fneural groove
- Gneural plate
- Hneural plate
- Ineural groove
8The 2 sides of the neural crest fuse creating the [blank_start]neural tube[blank_end] which later becomes the [blank_start]CNS[blank_end].
- Aneural tube
- BCNS
9Check all that apply. The neural tube
- Ais formed at 22 days
- Bis filled with fluid which becomes the ventricles
- Cis affected by folic acid deficiency
- Dis below the brain plate.
- Eis formed at 18 days
- Fis formed at 20 days
- Ghas gyri and sulci
10Embryonic stem cells are [blank_start]pluripotent[blank_end] which means that they can become [blank_start]any cell type[blank_end] in the body.
- Apluripotent
- Bany cell type
11Progenitor cells
- Aare daughter cells
- Balways make one copy of themselves
- Cmake multiple copies of themselves
- Dcan divide, but are limited
- Ecan divide an unlimited number of times
- Fproduce 1 specialization cell at the end of its proliferation cycle
- Gproduce 2 specialization cells at the end of its proliferation cycle
12Proliferation in the ventricular zone.
-[blank_start]stem cells[blank_end] reside in area around [blank_start]central canal[blank_end]
-[blank_start]migration[blank_end]: move from ventricular zone to appropriate region
--full differentiation- Astem cells
- Bcentral canal
- Cmigration
13What is neurogenesis?
- AThe mitotic division of nonneuronal cells to produce neurons
- BThe process of division of somatic cells that involves duplication of DNA
